Payment Terms

This document supplements the Terms of Service and applies only to paid plans and add-on packs. In case of conflict between the two documents on payment matters, this document decides.

1. Seller

The seller of paid plans and add-on packs is Filip Biskupski, conducting unregistered business activity (Art. 5 of the Law on Entrepreneurs of March 6, 2018), without NIP (tax ID) or REGON (business registry number). The seller uses the VAT exemption for small businesses (Art. 113(1) of the VAT Act) and is not a registered VAT payer – the same person running the ClassFlowy service. We will provide a correspondence address upon request sent to the email address below. Contact: support@biskupski.site.

2. Plans and add-on packs

ClassFlowy has four plans: Standard (0 zł – automatically set, cannot be "bought"), Plus (10 zł monthly), Pro (50 zł monthly), and Max (100 zł monthly). Any paid plan and any add-on pack can also be paid yearly – 12 months for the price of 10 (section 3). To each plan you can add extra packs – separately for recordings, photographs, chat, summaries, disk space, notes, assistant tools, access for connected chatbots (MCP), AI search, AI watch analyses (from the Plus plan), and textbooks (uploading pages and shelf space – both work and can only be bought from the Plus plan onwards). You can have at most one of each type of add-on – a higher threshold replaces a lower one, thresholds do not stack. We show exact thresholds and current add-on prices always before purchase and in Settings → Plans – we intentionally don't repeat the numbers here so this document doesn't get out of sync with what we actually offer.

Smart add-ons. These are packs built around one topic: Smart Lessons, Smart Chat, and Smart Features. Each costs 20 zł monthly or 200 zł yearly, works like any add-on pack (subscription, renews each period, limits every month), and adds up with regular add-ons. They also work without a paid plan and open their features on the Standard plan while the pack is active; when it ends, access returns to what your plan gives you, and your data stays. They only have the first-month promotion from section 3a. They cannot be bought as a voucher. Other plan features (including reading the board from video, and the school diary) still depend on your plan. The Sonnet, Opus and GPT levels depend on the plan or on an active Smart Chat.

Smart Lessons cover recordings, photos, descriptions, file storage, textbooks, original files, and notes. Smart Chat: conversations with the assistant, web search, MCP, computation, voice conversation, and the reader voice (reading aloud). Smart Chat also has its own limit for external models and, while active, opens those levels on the Standard and Plus plans too. You cannot pay for those models from the balance then: the balance works on them from the Pro plan. Smart Features: test pages, live answers, AI watch analyses, AI search, and live note credits, once that feature is available.

After a pack ends. Limits return to your plan's limits. We delete nothing: files and textbooks over the limit stay, but you cannot add new ones, and with a positive balance the space over the limit is charged the daily fee from section 3b. Files uploaded with the original kept stay that way; new ones are stored according to your plan.

For a Smart add-on we show what the cheapest set of regular add-ons giving at least the same limits would cost. This is a comparison with other products, not a price reduction.

AI search and AI watch analyses. These are regular add-ons: AI search on every plan, AI watch analyses from the Plus plan, at 5, 10, and 20 zł. After the plan and add-on limits run out they can be paid from the balance like other features. When there is nothing to pay from, search works without AI and watching runs on rules alone.

External models. The Sonnet and Opus levels (Claude by Anthropic) and GPT Luna, Terra, Sol and Astra (OpenAI) have a separate limit in conversations with the assistant. The Pro and Max plans include it, and the "External models" add-on pack (5, 10 or 20 zł monthly) increases it. The pack works from the Pro plan. Each of these models uses the limit at its own multiplier, shown when you choose the level. A conversation at such a level goes to that model's provider, as described in the privacy policy.

Usage limits (e.g., number of minutes of recordings, tokens in summaries and assistant chats, or file storage) apply to the billing period – unused limits do not carry over to the next period. With yearly billing the limit period is still one month: a paid year is 12 consecutive monthly periods, each with full monthly limits (not 12× the limit at once). You can always find current limits and how they're calculated in Settings → Plans, and the date of the next renewal in Settings → Limits; for the same reason we don't repeat specific numbers here.

Prices are in Polish zloty and include all applicable taxes.

3. How to buy

• Only subscription – monthly or yearly: card, Apple Pay, Google Pay, or Link, through the Payment Gateway (platnosci.biskupski.site) via Stripe. Charges repeat automatically every month or year until you turn off the subscription. This is the only way to buy plans and add-ons – we have not offered one-time purchases since 30.09.2026. The exception is the balance for paying for usage over the limit, which you top up with one-off payments (section 3b).
• Yearly subscription costs what 10 months cost (yearly price = 10 × monthly price from the price list) and gives you 12 months. You pay upfront for the whole year at the time of order – this is not a trial period. Limits renew monthly (section 2). The next year renews automatically at the same yearly price, until you turn off renewal.
• Plan and each type of add-on pack are billed separately – these are independent purchases. Changing one does not affect the others.
• Before each purchase, including plan or add-on threshold changes, you check in the purchase window that you accept these Payment Terms – without this the order button is inactive and payment doesn't start. When paying we record the date of this acceptance and the version of these terms (the date of its last change). The "I order and pay" button means an order with a payment obligation.

3a. Welcome promotions

Plan and add-on welcome promotions apply only to the first billing period – the first month, or with yearly subscription the first year – from the second you pay regular price. They only work on new purchases (when nothing is active in that plan or add-on type) and only for someone who has not yet used that promotion and never paid for that plan or add-on. With each purchase with a promotion we show it clearly in the purchase window and in Settings → Plans; if it's not there, you're buying at regular price.

Plan promotion – one, once per person. You can use only one of these promotions – monthly or yearly – once. After you use either, the rest stop showing for you and regular prices apply:

• Plus – first month free (30-day trial), then 10 zł monthly.
• Pro – first month 30 zł instead of 50 zł, then 50 zł monthly. Lowest price in 30 days before the discount: 50 zł.
• Max – first month 60 zł instead of 100 zł, then 100 zł monthly. Lowest price in 30 days before the discount: 100 zł.
• Plus yearly – first year 8 months' worth: 80 zł instead of 100 zł, then 100 zł yearly. Lowest price in 30 days before the discount: 100 zł.
• Pro yearly – first year 9 months' worth: 450 zł instead of 500 zł, then 500 zł yearly. Lowest price in 30 days before the discount: 500 zł.
• Max yearly – first year 9 months' worth: 900 zł instead of 1000 zł, then 1000 zł yearly. Lowest price in 30 days before the discount: 1000 zł.

Add-on packs – first month free, each once per person, independent of each other and of plan promotions: Recordings (add-on 20 zł), Whiteboard photos (20 zł), Assistant chats (5 zł), Lesson descriptions (20 zł), File space (10 zł), Unlimited written notes (3 zł), Assistant tools (add-on 5 zł – each profile: search, sandbox, and mixed, separately), MCP access (5 zł), and File saving (5 zł). Higher thresholds of these add-ons cost regular price from the start (monthly).

Smart add-ons – first month, monthly payment only, each once per person, independent of each other and of other promotions:

• Smart Lessons: first month free (30-day trial), then 20 zł monthly.
• Smart Features: first month 5 zł instead of 20 zł, then 20 zł monthly. Lowest price in the 30 days before the discount: 20 zł.
• Smart Chat: first month 10 zł instead of 20 zł, then 20 zł monthly. Lowest price in the 30 days before the discount: 20 zł.

Smart Credits have no promotion. Gift cards are not covered by promotions.

Add-on packs yearly – first year cheaper (except textbook add-ons, which have no welcome promotion yet, and Smart add-ons), each type once per person (the same "once" as the free first month – one or the other): add-on 20 zł monthly or less – first year 8 months instead of 10 (e.g., 20 zł → 160 zł instead of 200 zł); add-on 50 zł monthly or more – 9 months (e.g., 50 zł → 450 zł instead of 500 zł). The lowest price in 30 days before the discount is always the regular yearly price (10 × monthly price) – we show it with each such promotion.

• First month free is a trial subscription: you provide a card (also Apple Pay or Google Pay), for 30 days you don't pay and have full limits, and on day 30 we charge the first regular fee and then monthly. Before ordering we show the trial length, the date and amount of the first charge, and how to cancel; after ordering we send the same by email, and 7 days before the first charge – a reminder with the amount and date.
• You can end the trial at any time with no cost: turn off renewal in "Manage payments" (Settings → Plans) before it ends. We won't charge anything, and the plan or add-on works until the end of the trial; then the plan returns to Standard or the add-on disappears.
• You pay the Pro and Max discount (monthly) and every yearly promotion upfront when ordering (first month or first year at the lower price), and from the next period the subscription charges the regular price. Yearly promotions are a price reduction, not a trial period.
• Upgrading during a trial ends the trial: the new item starts as a regular new purchase – at full price and with a new billing period, with no charge difference calculated from the trial period (you don't pay for the trial period). Downgrading or "sideways" changes take effect at the end of the trial (section 5).
• The upgrade charge after a discounted first month is calculated under section 4 from regular prices, not from the promotional price.
• "Once per person" we check by email address – after normalization (case, and for Gmail addresses without dots and "+extras") – and we store only its one-way hash, including after account deletion, for 24 months (details in Privacy Policy). If someone bypasses this rule, e.g., with multiple accounts, we can refuse a promotion on the next purchase or cancel a subscription with a promotion – with no charge for the trial period.

First balance top-up ×2. On your first balance top-up you get a bonus equal to 100% of the payment, up to 50 zł: a payment up to 50 zł is doubled (50 zł → 100 zł), and with a higher payment the bonus is 50 zł (80 zł → 130 zł).

The promotion is available once per person, on the same terms as the other promotions in this section (email address after normalization, a hash kept for 24 months, including after account deletion). You do not get it if your account has already had another top-up, including an automatic one, unless the amount bonus on that earlier top-up was higher.

Bonuses do not combine. We do not add the promotion to the amount bonus from section 3b: you get the higher of the two. When the amount bonus is higher (e.g., 300 zł → +60 zł), the promotion is not used up and waits for your next top-up. Before you pay we show which bonus you will get and how much goes to your balance.

The promotion applies only to a top-up you order yourself on the page with this offer. It does not apply to automatic top-ups, gift vouchers, or balance from vouchers. It is used up only by a confirmed payment: a failed or abandoned payment does not use it up. If you pay for several top-ups in parallel, the promotion goes to the one confirmed first; the others get the regular amount bonus.

3b. Balance – paying for usage over the limit

• What the balance is. The balance is a prepayment in Polish złoty for using the service beyond the limits of your plan and add-on packs ("pay-as-you-go"). When the limit of a given item in your plan (together with add-ons) runs out, further usage of that item is taken from your balance – but only for features included in your plan or an active add-on pack: the balance alone does not unlock features or assistant tiers (for example a limit of 0 or a tier not available on your plan).
• Top-up. You top up the balance with a one-off payment through the Payment Gateway (BLIK, Przelewy24 or card) – in whole złoty, from 5 zł to 5000 zł per top-up. This is an exception to the rule that plans and add-ons are bought only as subscriptions. The balance goes up once the operator confirms the payment.
• Bonus. For a single top-up you get a bonus: from 100 zł +10%, from 300 zł +20%, from 500 zł +30%, from 1000 zł +40% (e.g. you pay 100 zł and 110 zł goes to your balance). We show the bonus when you choose the amount. The bonus cannot be paid out or refunded. The rules for the first top-up ×2 are in section 3a; the bonus from that promotion is a bonus within the meaning of this section: it does not expire and cannot be paid out or refunded.
• Price. For usage over the limit we take from your balance an amount according to the unit price list (a minute of recording, a photo, summary and chat tokens – by the assistant tier that answered –, a web search, computation, MCP calls, textbook uploads). Current prices in złoty are always shown in Settings → Plans → Balance ("Balance price list"), so you can check them before anything is taken from your balance; a price change applies to usage from the moment of the change. Amounts are calculated to one hundredth of a grosz. If work that has already started costs more than is left on your balance, we only take what is there – we cover the difference ourselves.
• Balance from before November 6, 2026. On that day the balance price list changed. We doubled a positive balance from before that day once, together with your spending limit and automatic top-up threshold, so on the day of the change it bought the same amount as before. We convert a top-up ordered before that day and confirmed after it, and a voucher bought before it, in the same way. The doubled part is not a payment: it cannot be paid out or refunded. When you withdraw from a top-up made before that day, we refund the unused part of the payment.
• File storage over the limit. You can upload files beyond your storage limit only while paying from the balance is on and your balance is above zero. For every started GB over the limit we take 0.16 zł per day. When the balance runs out (or you turn off paying from the balance, or reach your spending limit), your files stay and the fee stops – new files over the limit won't upload until you free up space or top up.
• Settings. Paying from the balance is on by default and you can turn it off ("Use balance after the limit"). You can set a monthly spending limit from the balance – counted in your plan's billing period (on the Standard plan, in the calendar month); once it is reached, the balance does not pay until the end of the period.
• Automatic top-up (optional, off by default). When you turn it on and your balance drops below the threshold you set, we charge your saved card (saved at your request during a top-up) with the amount you set (at least 5 zł, the bonus applies) – at most 3 times a day. You get a notification after each automatic top-up. If the charge fails twice in a row, automatic top-up turns off. You can withdraw your consent to automatic top-ups at any time by turning them off in the settings; you can remove the saved card in "Manage payments".
• Expiry and refunds. The balance does not expire. We do not pay out or refund unused balance – except for the rights you have by law. To withdraw from the contract within 14 days of a top-up, write to us at support@biskupski.site. We then refund, by the same payment method, the payment minus what you have already used: usage is taken from the payment first, and the bonus (including the one from the first top-up ×2) is left for last and is not refundable in any case. We will tell you the refund amount before we make it. The balance is lost when you delete your account.
• Payment refund or dispute. If a top-up payment is refunded or disputed (chargeback), we deduct the refunded amount and the whole bonus of that top-up from your balance (for a dispute – the whole top-up with the bonus). Your balance may then go below zero – until it is back above zero, paying from the balance does not work. If the dispute is resolved in our favor, we give the deducted amount back. After a refund or dispute the first top-up promotion does not come back, even if you did not get to use it. A dispute resolved in our favor restores the deducted amount together with the bonus, but does not give a second promotion.
• Plan bonus. On a paid plan you get, in each limit period, an amount for usage over the limit: Plus 2 zł, Pro 5 zł, Max 10 zł (also during a trial and with yearly billing, every month). The plan bonus is separate from the balance: we show it separately, with its expiry date. It expires at the end of the limit period, and any unused amount does not carry over to the next period. It cannot be paid out, transferred, or refunded. It does not count towards amount bonuses or the first top-up. After the plan and add-on limits run out, usage comes first from the plan bonus and then from the balance. It works without a top-up and also when you turn off paying from the balance, it does not count towards the spending limit, and it does not pay for file storage over the limit. When the balance is negative, the plan bonus does not work. When you switch to a higher plan during a period, we add only the difference. After you turn off renewal, the bonus stays until the end of the paid period. A refund of or dispute over the payment that paid for the plan cancels the remaining plan bonus. An account still using the old, higher plan limits paid for before they changed does not get the plan bonus; we start it from the first limit period after those old limits end.

3c. Gift cards

• What you can give. A gift card for balance (from 5 zł, with a bonus by the tiers in section 3b, calculated at purchase – the card shows the amount with the bonus), for the Plus, Pro or Max plan, or for an add-on pack – for 1 or 12 months (12 months for the price of 10). You buy a gift card with a one-off payment through the Payment Gateway (BLIK, Przelewy24 or card); first-purchase promotions don't apply to gift cards. After payment you get a code and a printable PDF card.
• Validity. Gift cards don't expire. A gift card can be redeemed once, on one account. A gift card can't be exchanged for cash.
• Redeeming. A gift card for a plan or add-on pack starts right away if you don't have that plan or pack; if you already have it, it waits in the queue and starts after the current period (with an active subscription – after you turn off its renewal), or you can convert it to its value in balance (the gift card's price). A gift card for a higher plan can be turned on right away – until the end of the current period, and the full price of your current plan then goes back to your balance – or after the period ends. Balance from a gift card (also from a conversion) follows the balance rules in section 3b.
• Withdrawal and refunds. You can withdraw from buying a gift card within 14 days only if the gift card hasn't been redeemed yet – write to us at support@biskupski.site (there is no refund button in the app). A refunded or disputed purchase cancels an unused gift card. A gift card that has already been redeemed isn't reversed.

3d. Smart Credits

Smart Credits. This is a pack in a monthly (20 zł) or yearly (200 zł) subscription. In each month of the pack you get 40 zł of credits for usage over the limit (PAYG), also with a yearly subscription: 40 zł every month. Credits count at the prices from section 3b.

Credits are separate from the balance. You see their amount and expiry date in the balance settings. They expire at the end of the pack month: they do not carry over to the next month and do not add up. They cannot be withdrawn, transferred or refunded. They do not count towards top-up amount bonuses or the first top-up promotion.

Once the plan and pack limits run out, the plan bonus is used first, then Smart Credits, and only then the balance. Credits only work for the features you have in your plan or active packs: they do not open any feature themselves. External models work on credits only from the Pro plan. Credits do not cover the fee for file storage over the limit.

On a refund or dispute of the payment for the current pack period, unused credits are forfeited. Used credits are settled like the plan bonus in section 7a.

4. Upgrading to a higher plan or higher add-on threshold

You pay the price difference (monthly prices, according to the price list), regardless of how many days are left in your current period. In return you immediately get the full limits of the new plan or add-on threshold for the entire current period – as if it had been paid for at the new price from the beginning. With yearly billing (yearly to a higher yearly) section 4a applies.

Exception – file space add-ons: the charge depends on the number of days left in your current period (with a minimum charge) and never exceeds the full price difference.

The new, higher limits work immediately after payment, with your current-period usage so far – nothing resets. The billing period doesn't change – your next full charge at the new, higher price falls on the same day as before. We always show the upgrade amount and what you're upgrading before payment.

You pay the upgrade yourself on the Stripe payment page (card, Apple Pay, or Google Pay) – we don't charge it automatically from your saved card. Usually payment has two steps: first you confirm the new subscription (the page will show "0 zł today" and "free" days until your old renewal day – this is not a trial, just time already paid for by your current plan or add-on), then you go to the upgrade payment page. If you don't pay it, in Settings → Plans you can pay it later with "Pay upgrade"; without the upgrade charge, the new plan or threshold starts on your next renewal (which will charge the new price).

4a. Yearly billing: plan or add-on threshold changes

Yearly to higher yearly (plan or add-on of the same type): you pay the difference in monthly prices for the months left until the end of the paid year, including the current one – never more than the difference in yearly prices. We calculate it from the regular prices in the price list, also if your first year was promoted. In return you immediately get the full limits of the new item for the current month and every following month of the paid year. Your renewal date doesn't change – next year will charge the new yearly price.

Exception – file space add-ons yearly: the charge depends on the number of days left until the end of the paid year (with a minimum charge) and never exceeds the full difference in yearly prices.

Monthly to yearly: yearly billing starts at the end of your current, already-paid month – we charge the first yearly fee on your old renewal day, and nothing changes until then and you don't pay now (nothing is lost or refunded). If you upgrade at the same time, you pay the difference for the current month immediately (section 4) and immediately get its full limits.

Yearly to monthly (also to a higher plan or threshold) and yearly to lower yearly or "sideways": the change takes effect at the end of your paid year, with no refund for remaining months and no charge – you have your current item with full monthly limits until then. You can have a higher plan immediately by choosing its yearly version (upgrade charge as above).

You pay the upgrade yourself on the payment page – same as section 4 (two steps, never automatically from your saved card). We always show the upgrade amount and what you're upgrading before payment.

5. Downgrading to a lower plan, lower add-on threshold, or "sideways"

The change takes effect at the end of your current, paid period – no refund for time still paid at your current level, and no extra charge now. You have full access to your current plan or add-on until then, and from the next period the new item starts (lower threshold or add-on at the same price but different profile). You can see a planned change in Settings → Plans; while it's pending, you can't schedule another change in that slot. With yearly billing "end of period" means the end of your paid year (section 4a).

6. Renewal, cancellation, and end of period

• Turn off a subscription at any time with "Manage payments" (Settings → Plans) – this is Stripe's portal where you manage your card, see payment receipts, and turn off renewal. After cancellation your plan or add-on works until the end of the already-paid period (with yearly billing – until the end of the paid year, with monthly limits), with no refund for unused time, then it returns to the Standard plan (plan) or disappears (add-on); uploaded files and notes always stay.
• If we can't charge for the next period, we retry for a few days. Your plan or add-on stays active for another 3 days after the paid period ends; if payment doesn't succeed in that time, it returns to its state before the purchase.
• One-time purchases for 30 days, which we sold until 30.09.2026, still work until the end of the already-paid period but don't renew – to stay longer you must buy a subscription (the first full charge then falls only at the end of what's already paid).

7. Refunds and disputes

Write to support@biskupski.site about a refund or complaint about payment. A refund always goes back to the same payment method you used. We review your request and respond within 14 days of receiving it. A payment dispute (chargeback) is treated exactly like a refund request.

A refund (or dispute) takes back exactly as much as the specific charge gave – no more:

• Full refund of a charge that paid a current, active subscription period, or a dispute over that charge – ends access immediately. Because a subscription without a paid period would anyway charge another month's fee, we automatically cancel it in the payment gateway too – you don't need to do anything, there will be no further charge.
• Refund of an older, no longer active renewal (one that paid a past, ended period) doesn't touch the period that is active today – we don't take away access you already paid for with a newer charge.
• Partial refund doesn't take away access.
• Refund of an upgrade charge (before we confirm it) reverts you to your previous plan or add-on.
• Refund of the purchase of a previously planned downgrade cancels that planned change.
• Refund of an old one-time 30-day purchase shortens the paid period by exactly those 30 days; the item disappears only when nothing of the paid time remains.

A refund that is not full but proportional to unused time – because this document provides for it (e.g., canceling a paid plan after terms or limit changes, Terms section 8) or because we decide to go easy – we make under the rules in section 7a below. A refund on request made through the Helper is calculated according to section 7b, never below the amount from section 7a where section 7b provides for it.

7a. Proportional refund

This section applies only to proportional refunds (not full) that we make on our own initiative or because this document provides for it – see "When this section applies" below.

We refund the part of the price of the plan or add-on for the current billing period that corresponds to what is left of the period. We take into account both the remaining days and the use of that item's periodic limits – whichever is used more counts. Disk space does not count: it's storage, not usage in a period. With a yearly subscription we refund in full the months that haven't started yet, and the current month on the same rules. We deduct 2 zł and 1% of the price from the refund for handling the payment and its refund; if nothing is left after that, there is no refund. We will tell you the exact refund amount before we make it.

When this section applies:

• When you cancel a paid plan or add-on within 14 days of notice of a change to these terms, prices, or limits you disagree with – the right to this refund comes from the Terms, section 8 (and section 14).
• When we refund part of a charge at your request or in good will (section 7 above), instead of a full refund.
• Anywhere else in this document that directly promises a proportional refund (not full) to unused time.

What this section does NOT cover. The 2 zł and 1% are a deduction we agree to in this document – so it can never reduce a refund you have a legal right to. When law requires a full refund or a refund with no deductions, the law applies, not this section – especially for:

• Digital content or digital service non-conformity (Art. 43a et seq. of the Consumer Rights Act),
• the legal right to withdraw within the time limit, if it was not validly excluded (section 10) – the amount owed there is calculated by the law itself (Art. 35 of the Consumer Rights Act), with no deductions from this section,
• an error on our side, e.g., a double charge (section 13).

7b. Refund on request made through the Helper

If you want to cancel a paid plan or add-on pack before the end of its period, you can ask for a refund through the Helper (help chat). Such a refund is voluntary on our part and does not limit any rights you have under the law.

We refund the unused part of the amount paid for the current period (reduced by earlier refunds of this payment). Whichever of two parts is larger counts: the time that has passed or the use of limits in this period. From that amount we deduct the payment operator's commission, a fixed deduction and a deduction for each feature outside the Standard plan that you used in this period – we list these features on the card before you confirm. Ordinary use of limits that are also included in the Standard plan is not a feature; the exception is using the Helper beyond the Standard plan limit. The refund is never negative: if nothing is left, it is 0 zł.

We never deduct for data export (including the faster export on paid plans), account deletion, contacting support, or any other action related to your rights. Reports to us, refund requests, exports, account deletion and messages related to them are also not counted toward the Helper limit.

First 14 days. For 14 days from payment we also calculate the refund under section 7a, and when you have the statutory right of withdrawal (section 10), also the amount for unused time without any deductions, and we give the highest of these amounts. This section never gives less than what section 7a or the law guarantees. The same applies to canceling within 14 days of an announced change to the terms, price list or limits (Terms of Service, section 8).

How it works. Before you confirm, the Helper shows the exact refund amount and its breakdown. When you confirm with the button, the plan or pack ends immediately and renewal is turned off. We send the money after the decision of the owner of the service, who may agree or refuse. If refused, the plan goes back to what it was, including renewal. If the paid period expires while the request is pending, we do not restore the time that has already passed. A payment covered by a dispute or already refunded is not refunded a second time. The refund for a period made up of a purchase and an upgrade charge is set individually.

Packs. The same rule applies to the pack's own period. Only the use of what the pack added above the plan counts, and we do not apply the feature deductions, because we calculate them from the plan price.

8. Immediate cancellation by us

Besides the refunds above, in justified cases (e.g., on your express request or if we suspect abuse) we can cancel your subscription in the payment gateway immediately, skipping the usual cancellation process – the same as the "Cancel immediately" button in the gateway's panel. However, this does not take away access you already paid for – your plan or add-on works until the end of the paid period the same way as after normal cancellation, just with no further attempts to charge the next fee. You lose access before the end of the period only through a refund or dispute (section 7).

9. Payment operator

Payments are handled by the Payment Gateway (platnosci.biskupski.site) – a payment system run by the seller in section 1 – via Stripe. You enter your card number and bank login directly on Stripe's page; neither ClassFlowy nor the Payment Gateway see or store them.

10. Right to withdraw (14 days)

If you are a consumer (or a natural person entering an agreement directly related to your business activity, if the agreement's content shows it has no professional nature for you), you have the right to withdraw from a plan or add-on purchase agreement within 14 days of its conclusion, without giving a reason – write to support@biskupski.site.

However, there is an exception that applies to what we sell. Plans and add-ons are digital content not supplied on a physical medium, and in the part relating to current access to processing and server storage – also a digital service. Since the amendment to the Consumer Rights Act that took effect January 1, 2023, this same exception covers both categories. Access to higher limits turns on immediately after payment, before the 14-day period ends. Under Art. 38(13) of the Consumer Rights Act, you lose the right to withdraw once we start delivering to you, if you previously:

• explicitly agreed that we start providing before the withdrawal period ends, and
• acknowledged that by doing so you lose the right to withdraw.

There is one more condition, this time on our side: we must confirm to you that we've concluded the agreement – including the content of your consent and statement – no later than when we start providing (Art. 21(1) of the Consumer Rights Act). We do this automatically: when access turns on for the first time (new purchase or paid upgrade to a higher plan/add-on), you immediately get an email with confirmation – what you bought, for how much, when the next renewal is, how to cancel, and the exact text of your consent together with when it was given.

We collect your consent and statement by checking a box in the purchase window, right before you go to payment – you can't proceed without checking it – and we record that check together with the exact time it was given for that specific charge. We show (and require) the box only when the change actually gives immediate access – on new purchases and upgrades to a higher plan or add-on threshold. When downgrading to a lower plan/threshold or renewing what you already have, access is postponed until the end of the paid period anyway – you don't lose anything, so there's no box. If you don't check the box (e.g., you buy another way, through the administrator), you have the legal right to withdraw under general rules for 14 days, and we refund proportionally to unused time – under the law itself (Art. 35 of the Consumer Rights Act), without the 2 zł and 1% deductions from section 7a: this is a legal withdrawal right, not a voluntary proportional refund, so we don't reduce it.

11. Invoices and payment receipts

ClassFlowy does not issue invoices or receipts. In the "Manage payments" portal (Stripe) you will find payment history and can download a payment receipt – for a consumer this, together with the purchase confirmation email, is enough proof of payment. The seller conducts unregistered business and does not issue VAT invoices. On request we issue a rachunek (a bill – an invoice without VAT, Art. 106b(3)(2) of the VAT Act) and keep simplified sales records. Write to support@biskupski.site.

12. Purchases by minors

If you are aged 13 to 17, you have limited legal capacity (Art. 10–22 of the Civil Code). Buying a plan or add-on – especially a subscription that renews automatically – is usually not a "minor everyday matter," so to be valid such an agreement needs your parent's or guardian's consent, ideally before payment. We do not verify this at purchase – it's an obligation that rests with you and your parent/guardian, not a process we verify technically.

Without that consent a parent or guardian can reject the purchase agreement – then we refund the amount paid and stop renewal, as with a normal withdrawal (section 10). A parent or guardian can also turn off renewal at any time on your behalf by writing to us at support@biskupski.site. If you'd prefer that you can't buy anything on your own before age 18, write to us – we can set a plan manually, without online payment (see Terms, section 8).

13. Payment complaints

Report a payment complaint (e.g., wrong amount charged, plan didn't turn on despite payment) to support@biskupski.site – say what you bought and when. We respond within 14 days of receiving it. A justified complaint results in a refund to the same payment method or fixing the service (e.g., manually turning on the paid plan).

14. Account deletion

When you delete your account, all active subscriptions are canceled immediately – we won't charge the next fee. We do not automatically refund the unused part of the paid period; if you want it, write to support@biskupski.site before deleting your account (see also section 7).

15. Plan or add-on set by the administrator

Besides purchases, a plan or add-on can be set manually by the administrator – for example when online payments are off, or in individual cases. Such a setting takes priority over what would result from a purchase:

• Indefinite – does not expire by itself. You can't replace it with a regular purchase in the app (the system will show you can't buy) – write to us if you want to change it.
• With an end date – expires exactly that day: the plan returns to Standard or the add-on disappears – unless in the meantime it's extended by a subscription. Then the purchase extends it as if it were already a paid period: it counts from that date, and when upgrading you pay the price difference (section 4).

16. Changes, governing law, and out-of-court dispute resolution

We will notify you of changes to this document in the service with notice before they take effect. It is governed by Polish law; if you are a consumer, this does not deprive you of the protection resulting from your country of residence's law, which cannot be excluded by agreement. Out-of-court ways to resolve disputes, including the EU's ODR platform, are described in the Terms of Service.
