ReBrayn Terms of Service

Version 1.1 · last updated: 25 October 2026

Provisional text, pending final legal review.

These Terms govern the use of ReBrayn, the online study service provided by ADC S.r.l. Please read them carefully: when you accept them at your first sign-in you enter into a contract with us. How we process your personal data is explained in the Privacy Policy and the Cookie Policy (in ReBrayn: Settings › About), which form part of these Terms.

2. Words we use

3. How the contract is made

3.1 To use ReBrayn you create an Account and, at your first sign-in, accept these Terms by ticking the box. The contract for the Basic Plan is made at that moment and costs nothing.

3.2 The contract for a paid Plan is made when you complete the purchase with the payment provider and the payment succeeds (section 7).

3.3 We keep in your Account the version of these Terms you accepted, its language, and the date and time of acceptance.

3.4 The contract is made in Italian. This English version is a translation; if the two differ, the Italian version prevails, unless a mandatory consumer-protection rule provides otherwise.

4. Who may use ReBrayn

4.1 By accepting these Terms you declare that you are at least 14 years old, the minimum age to create an Account. If you are under 18, you may buy a paid Plan only through a parent or legal guardian, who accepts these Terms on your behalf.

4.2 The Account is personal. You may not transfer it or share your credentials. You are responsible for keeping your password confidential and for what happens with your Account; if you suspect unauthorised access, change the password at once and write to us.

4.3 You must provide a valid e-mail address of your own: we use it to verify the Account, recover the password and send you service messages.

5. What ReBrayn offers

5.1 ReBrayn is an online study space. Within the limits of your Plan you can:

5.2 Your Materials and Outputs are stored on the cloud servers we use for the service, in the European Union, and are synchronised across the devices you sign in from. They stay stored until you delete them or delete your Account (section 12). When you delete a file it no longer appears in the app; a copy stays in our storage [● until the Account is deleted / ● days], as set out in the Privacy Policy. Some information is also kept in your device's browser, so the app runs faster and no change is lost when the connection drops.

5.3 ReBrayn needs an up-to-date browser and an Internet connection, at your own cost. Some features are available only on the Pro or Max Plan, and every Plan has usage limits (for example number and size of files, number of artificial intelligence requests, OCR pages, transcripts). Current features and limits are shown in the app, in the Plan and usage section.

5.4 We keep improving ReBrayn: we may add, change or replace features and technical providers. If a change significantly reduces the essential features of your paid Plan, we tell you reasonably in advance and you may withdraw from the contract free of charge, with a refund of the unused part of the price.

6. Artificial intelligence features

6.1 Many ReBrayn features use artificial intelligence models provided by third-party companies. When you use one of these features, or when a Material is processed after upload, the necessary parts of the Material (for example the text, an image of a page or the audio) and your request are sent to the model provider, which returns the result. The list of providers and the safeguards for your data are in the Privacy Policy (in ReBrayn: Settings › About).

6.2 Automatically generated Outputs may be incomplete, inaccurate or wrong, even when they look convincing. They are a study aid: always check them against the sources and do not rely on them alone for important decisions. ReBrayn does not give medical, legal, financial or professional advice.

6.3 We do not use your Materials or Outputs to train artificial intelligence models, and the providers we use process them under their terms for API use.

7. Paid Plans, prices and renewal

7.1 Besides the Basic Plan, which costs nothing, ReBrayn offers the Pro and Max Plans, billed monthly or yearly. Price, duration and content of each Plan are shown before purchase. As of 29 October 2026 the prices are: Pro 9 € per month or 89 € per year; Max 13 € per month or 129 € per year, VAT included.

7.2 Payment is handled by Stripe, by card or PayPal. We do not receive or store your full card details.

7.3 The subscription renews automatically at the end of each period (month or year) for the same period, at the price then in force, until you cancel it. You can cancel at any time in the app: cancellation takes effect at the end of the period already paid, until which you keep the Plan. Cancellation does not give a refund of the current period, except for the right of withdrawal in section 8 and the cases provided by law. Before an annual subscription renews we send you a reminder [● 30] days in advance.

7.4 Plan usage limits reset every month on the payment day (for annual Plans, the same day of each month); for the Basic Plan, on the day you signed up or returned to the Basic Plan, each month.

7.5 You can move to a higher Plan at any time in the app: the change is immediate and you pay at once the difference calculated pro rata on the remaining period; the new period starts that day. To move to a lower Plan, cancel the current one and subscribe to the new one when it ends.

7.6 If a payment fails, the payment provider retries for a limited time and the Plan stays active meanwhile. If the payment does not arrive, the Account returns to the Basic Plan: everything you have already created stays yours and usable, but you cannot add new Materials beyond the Basic Plan limits.

7.7 We may change prices for future periods. We notify you by e-mail at least [● 30] days before a new price applies to your renewal; if you do not accept it you may cancel before the renewal.

7.8 Receipts and invoices: issued by ADC S.r.l. on request; for businesses the electronic invoice goes through the Italian Exchange System (SdI).

8. Consumer right of withdrawal

8.1 If you are a Consumer, you may withdraw from the contract for a paid Plan within 14 days of its conclusion, without giving any reason and without costs other than those stated below.

8.2 At purchase you may expressly ask the service to start at once, before the withdrawal period ends. In that case, if you then withdraw, we refund the price paid minus an amount proportionate to the service provided until you told us you were withdrawing. You lose the right of withdrawal only if the service has been fully performed.

8.3 To withdraw you can use the "Withdraw from contract" function in the Subscription section of the app, always available during the 14 days, or send us a clear statement, also with the form below, to info@rebrayn.ai or to the PEC alessandrodeconcinisrl@pec.it. We confirm receipt at once on a durable medium (e-mail).

8.4 We refund what is due without undue delay and in any case within 14 days of receiving your withdrawal, using the same means of payment you used, unless agreed otherwise. From the withdrawal the Account returns to the Basic Plan.

8.5 Cancelling the renewal (section 7.3) and withdrawing are different: cancelling stops future renewals; withdrawing ends the current contract within the 14 days.

9. Your Materials and your rights

9.1 Materials and Outputs remain yours. We acquire no ownership of them.

9.2 To provide the Service you allow us, for the duration of the contract and only for this purpose, to store, copy, convert and process the Materials, to send the necessary parts to the technical providers listed in the Privacy Policy, and to show them to you and to the people you choose to share them with.

9.3 You are responsible for the Materials you upload. You warrant that you have the right to use them (for example because you are the author, you hold a lawful copy for personal study, or they are freely usable) and that using them in ReBrayn does not infringe copyright, other third-party rights or the law.

9.4 Do not upload other people's personal data without a right to do so, and do not upload special categories of personal data (for example data about health, political or religious opinions, sexual orientation, biometric or criminal data) relating to identifiable persons, unless already lawfully made public. Study materials dealing with these subjects in general (a medical textbook, a legal code) are not covered by this ban. You hold us harmless from the consequences of using third-party data in breach of this section.

10. Sharing

10.1 You can create a link to share a Material with the Outputs you choose. Whoever receives the link must sign in with their own ReBrayn Account to see it and can import a copy into their Account.

10.2 You can revoke the link at any time: from then on nobody can open or import it. Copies already imported by others stay in their Accounts and are not deleted by the revocation or by deleting your Account. Share only what you have the right to share.

11. Proper use of the service

11.1 You agree not to use ReBrayn to:

11.2 If you seriously breach these Terms we may suspend the Account, after warning you where possible, or terminate the contract. On termination for your serious breach the current period is not refunded, to the extent permitted by law.

12. Duration, cancellation and Account deletion

12.1 The contract lasts as long as you have an Account. You can delete the Account at any time in the app (Settings › Account › Delete account). If you have an active subscription, you can delete the Account once the period already paid has ended: first cancel the renewal.

12.2 Deletion is final and immediate: you lose access at once (within a few minutes on devices already signed in) and we delete your Materials, Outputs and Account data, normally within minutes and at most within [● 30 days]; backup copies expire within 35 days. We keep only what the law requires, as stated in the Privacy Policy. Before deleting the Account, export what you want to keep (section 5.1).

12.3 When a subscription ends without renewal, the Account returns to the Basic Plan: your Materials and Outputs are not deleted.

12.4 We may discontinue the Service with at least [● 60] days' notice, during which you can export your data; in that case we refund the price already paid for the unused period.

13. ReBrayn's intellectual property

The software, design, trademarks, texts and other elements of ReBrayn belong to ADC or its licensors. We grant you a personal, non-exclusive, non-transferable licence to use them for the duration of the contract and under these Terms. Open-source software included in ReBrayn remains governed by its own licences.

14. Availability and third-party services

14.1 We do our best to keep ReBrayn available and reliable, but there may be interruptions for maintenance, updates or failures, including those of third-party providers (cloud infrastructure, artificial intelligence models, payments). When possible we announce planned maintenance in advance [● channel, for example a notice in the app].

14.2 Some features depend on third-party services that may change or stop. In that case we may replace the provider or change the feature, within the limits of section 5.4.

15. Warranty and liability

15.1 If you are a Consumer, you are entitled to the conformity of the digital service under the Italian Consumer Code (articles 135-octies and following). Nothing in these Terms limits the rights the law grants you on a mandatory basis.

15.2 We are liable for damage caused by wilful misconduct or gross negligence and for personal injury. Outside these cases, and subject to mandatory rules, we are not liable for indirect damage or for data loss due to causes beyond our control, and our total liability to you is limited to what you paid us in the 12 months before the event (or [● amount] euro for the Basic Plan).

15.3 We recommend keeping a copy of your most important Materials with the export function.

16. Changes to these Terms

16.1 We may update these Terms, for example for new features, new providers or changes in the law. When the Terms change, we show you the new version in the app before you continue, and you accept it there. If you do not accept it, you can export your data and delete the Account; if you have a paid Plan you can also withdraw from the contract free of charge, with a refund of the unused part of the price.

16.2 Changes required by law, or that do not disadvantage you, may apply at once.

17. Governing law, complaints and disputes

17.1 These Terms are governed by Italian law. If you are a Consumer living in another EU country, you keep the protection of the mandatory rules of your country.

17.2 For any complaint write to info@rebrayn.ai: we answer within 14 days.

17.3 Disputes with a Consumer belong to the court of the Consumer's place of residence or domicile. In all other cases the court of Padova, Italy, has exclusive jurisdiction.
