Privacy Policy and Notice

This page explains which personal data is processed when you use sınavlab and what your rights are. Last updated: 10 November 2026.

1. Data controller

Your personal data is processed by sınavlab as the data controller under the Turkish Personal Data Protection Law No. 6698 (KVKK). You can reach us at destek@sinavlab.app.

2. Which data do we process, and why?

• Your account details: first and last name, phone number, email address and an irreversible hash of your password. Used to create your account, let you log in and contact you when needed. Login codes are sent by email through Resend.
• The question pages you upload: photos and PDF pages are processed on the server to prepare the answer key. Each job is deleted automatically together with its photos and solutions 4 hours after the last action.
• Your usage information: how many questions you solved, your remaining question credits, your goal information and the messages you write in the support form.
• Your purchase request: plan, amount, date and status together with your name, email and phone. Used to manage payment and question credits.
• PDF tools: the files you upload are kept only temporarily while the job runs and are deleted as soon as it finishes. Files are not sent to AI services. The “JPG to PDF” tool runs in your browser without sending files at all. Passwords you add to or remove from a PDF are not stored.
• Visit and usage statistics: to see how many people use the site and which tools are used, we count page views and tool usage. A visitor is counted with a one-way summary that changes every day and is made from the connection and browser details; your IP address, cookies or identity are not stored and nobody can be recognised from it. Bots are not counted.
• Notification subscription: if you turn on notifications, your browser creates a subscription record so we can tell you when your job is done. You can turn it off in your phone or browser settings or in My account.

Information such as location is not requested.

3. AI services and transfer abroad

To solve questions, page images are sent to AI models through OpenRouter. The models used depend on the plan you choose and include models from Anthropic (Claude), Google (Gemini) and Alibaba (Qwen). The servers of these companies may be outside Turkey; each service's own privacy policy applies. So if personal information such as your name or address appears on your pages, we recommend covering or cropping it before uploading.

Resend is used for sending email and Google (AdSense) for advertising. Your phone number is not shared with anyone.

4. How long is your data kept?

• Uploaded pages and solutions: deleted 4 hours after the last action.
• Your account details and usage records: as long as your account is open. When you delete your account, your profile, question credits, jobs and support messages are deleted.
• Purchase records for which payment was received and credits granted (plan, amount, date): kept for the legal period required by tax and accounting rules.
• System backups are encrypted and kept only so we can recover after a failure. Deleted information may remain in these encrypted copies for a while until the backups are renewed.

5. Cookies

sınavlab uses two kinds of cookies and similar technologies:

• Essential cookies: keep you logged in and remember your appearance and plan choice and your cookie preference. The site does not work without them.
• Advertising cookies: Google AdSense ads are shown on blog and PDF tools pages. Google and its partners may use their own cookies to show and measure ads.

If you turn off “Personalisation and advertising” in the cookie preferences, you see non-personalised ads; the ads themselves do not go away. No ads are shown on pages that require login, such as your account and the question-solving screens. You can read how Google uses advertising data on Google's page and manage personalised ads in Ad Settings.

You can change your cookie preference at any time with the button below.

6. Your rights

Under Article 11 of the KVKK you have the right to learn whether your data is processed, request information if it has been processed, learn the purpose of processing and whether it is used accordingly, know the third parties it is transferred to at home or abroad, request correction if it is incomplete or inaccurate, request deletion or destruction, and object to its processing. If you have suffered damage, you can request compensation and complain to the Personal Data Protection Board.

You can download your data as a file under My account → My data and delete your account from the same place. For other requests, write to destek@sinavlab.app.

7. Accuracy of answers

Answers are produced by AI models and may contain errors. The results of several models are compared; questions on which they do not agree are marked separately. Use the answer key as a support for checking, not as a final result.
