Privacy Policy

What we collect

• Account data: email address, username, and a hashed password.
• Study data: your answers, test history, progress, and flagged questions.
• Order data: the exam purchased, amount, order code, payment status, and payment reference (such as a transaction ID or payment proof you upload). Card details are handled by our payment providers and never reach our servers.
• Technical data: a login cookie that keeps you signed in, and standard server logs.

How we use it

• To run your account, save progress, and unlock exams you bought.
• To process and verify payments and handle refunds.
• To answer support requests and prevent abuse.

We do not sell your data and we do not show third-party ads.

Who we share it with

• Payment providers, only what is needed to complete and verify a payment.
• An AI model provider, which receives the question text when you request an AI explanation. Your account details are not included.
• Hosting and database providers that store the site's data.

Retention and your rights

We keep account and study data while your account is active, and order records as long as needed for accounting. You can ask us to access, correct, or delete your data at any time by emailing [email protected]. Deleting your account removes your study data and access to purchased exams.
