In one sentence

Repaso reads the study material you send it and writes questions about it, bringing each question back on the day you are about to forget it. To do that, it keeps what you answered.

Terms of Use

1. What the service is

Repaso is a spaced repetition study tool. You send a material (today, a PDF or text), an automated system reads it and writes questions, and the app schedules when each question should come back.

2. Your account

You need an email address and a password. You are responsible for keeping your password safe. If you suspect improper access, change it from the recovery screen itself.

We do not ask for, see, or store your password in readable form — authentication is handled by Supabase, which keeps only a cryptographic digest of it.

3. The material you send — the most important part

You declare that you have the right to use the material you send.

Repaso does not verify this, and would have no way to. If you send course notes, a book, or study material, responsibility for that use is yours.

In return, we commit to the following, and it is implemented in the code, not merely written here:

• Your material is yours. It is visible only to your account.
• We do not use your material to serve anyone else. The questions

generated from it are not offered to other users.

• We do not sell, license, or publish your material.
• The file itself never leaves your device. See "The PDF" in the

privacy policy.

There is one exception, and it is written in section 6: illegal, indecent, or improper material may be removed.

4. What the tool is not

• It is not a teacher or tutor. Questions are generated automatically

and may contain errors. Check them against the original material before studying from them as if they were an answer key.

• It does not replace the material. It is practice on top of it.
• It does not guarantee passing any exam.

5. Plans and billing

| | | |---|---| | To try it | 1 material, up to 40 pages — free | | Monthly | 4 materials per month, up to 300 pages each — R$ 79.90 | | Single material | R$ 24.90 |

• Prices are in Brazilian reais (BRL) and billing is processed by

Stripe. Outside Brazil, your bank converts at its own rate, and the amount on your statement may differ from the one shown on screen.

• We do not see or store your card details — they go straight to

Stripe.

• You can cancel whenever you want, and access continues until the

end of the period already paid for.

• There is no automatic refund for a period already used. If something

went wrong on our side, talk to us — we sort it out case by case.

6. Acceptable use, and what can be removed

Repaso is a study tool. Do not send:

• illegal material, or material you do not have the right to use;
• indecent, obscene, or pornographic material;
• material inciting violence, hatred, or discrimination;
• material that is improper for a study tool, including any content

exposing another person's personal data;

• anything intended to overload the service or work around its limits.

We may remove from Repaso, without prior notice, any material falling under the above. Removing means truly deleting: the material leaves the database and takes with it the units, the questions, and the study history generated from it. There is no recovery — this is not the trash you have inside the app, from which you restore what you deleted yourself.

In serious cases, or when it happens repeatedly, we may also suspend or close the account.

Two things so there is no misunderstanding:

• We do not read anyone's material as a routine. What exists is an

administration panel listing the materials sent (title, size, status) — and that is where removal comes from, when it is necessary. There is no automated content scanning, and no prior moderation.

• Removing a material does not refund credit. The processing was

already done and paid for at the moment the questions were generated. This also applies when you are the one deleting.

7. End of the service

This is a new product, run by a small team. If it is ever discontinued, we will give notice in advance and you will be able to export all your data — that function already exists today, under Settings.

8. Changes to these terms

If we change something relevant, we will give notice in the app. Continuing to use it after the notice means accepting the new version.

9. Governing law

These terms are governed by Brazilian law, with jurisdiction in the district where the person responsible for Repaso is domiciled.

Privacy Policy

1. What is collected

You provide:

• name, email, and password
• country
• exam date, study days and minutes (optional)
• the study material you send

Use generates:

• which questions you answered, whether you got them right, and how long

you took

• the state of your memory per question (when it should come back)
• account creation date and last access

The device reports:

• when something breaks on screen, we record the error message, the

screen where it happened, and the browser type. That record does not store who you are — there is no user identification in it.

We do not collect: location, contacts, calendar, or data from other applications. We use no tracking cookies and no advertising.

2. The PDF — how it actually works

When you send a PDF, it is opened and read inside your own browser. The file is never uploaded to or stored on our servers.

What leaves your device is the extracted text, in pieces, sent at the moment the questions are generated.

3. Where the text goes

This is the part that demands full transparency.

To write the questions, the text of your material is sent to Anthropic, which operates the language model Repaso uses. It is one-off processing, done at the moment of generation.

We also store, alongside each question, the literal excerpt from your material that proves the answer — that is what lets us show you the exact paragraph when you get it wrong, and what guarantees the question was not invented.

4. Where the data lives

| Service | What for | Where | |---|---|---| | Supabase | database and login | servers outside Brazil | | Vercel | site and processing hosting | servers outside Brazil | | Anthropic | question generation | servers outside Brazil |

In other words: your data is processed outside Brazil and Argentina. By using Repaso you agree to that transfer.

5. Who has access

• You, to your account.
• The person responsible for Repaso, through an administration panel,

to follow usage and solve problems. That panel shows name, email, country, activity and aggregate performance, and the list of materials sent — title, size, and status, not the content. That is where access is granted, an account problem is fixed, and a material is removed in the cases of section 6 of the Terms.

• Nobody else. We do not sell or share data with third parties for

commercial purposes.

6. Your rights

• See and take your data: under Settings → "Export my data" you

download a file with everything — preferences, subjects, questions, your answer history, and the state of your memory.

• Delete a material: on the Material screen, on each subject.
• Delete the whole account: under Settings → "Delete my account". You

confirm by typing your email and it happens immediately, without depending on anyone on our side: out go your materials, the questions generated from them, your answer history, and the state of your memory. There is no trash and we keep no copy. The screen itself offers the export before you confirm — afterwards there is no way back.

• Correct your data: name, country, and preferences you change under

Settings.

7. How long we keep it

As long as your account exists. When you delete the account, we delete your personal data, your materials, and your history.

Material removed under section 6 of the Terms is deleted immediately, along with the questions and history that came from it.

Error logs (which do not identify you) may remain for up to 90 days for diagnosis.

8. Security

• Access to data is controlled in the database itself, by rules that

prevent one account from reading another account's data.

• The keys granting broad access stay only on the server, never in the

browser.

• No system is immune. If there is an incident affecting your data, we

will tell you.

9. Minors

Repaso is not intended for children under 13. Between 13 and 18, use must be authorised by a guardian.

10. Who is responsible, and contact

Repaso is operated by Lukas Rocha Zuccarello, an individual, in Brazil. He is the one who decides what is collected, what it is for, and how long it is kept — that is, he is the controller of your data.

Questions, deletion requests, or anything else about your data:

zuccarellolukas8@gmail.com

Deletion requests are handled within 7 days. You can also delete your account yourself, inside the app, under Settings.
