Privacy Policy

• Account information: your name and email address.
• Study data: your answers, scores, time spent, flagged questions and personal notes.
• Technical data: IP address, device and browser type, language, and the pages and actions on the site.
• Order data: order code, plan chosen, amount and payment status.

We do not collect phone numbers and do not store card or bank details — payments are handled by the PayOS gateway on their own systems.

We keep two kinds of email strictly apart:

• Service email (password, password reset, order confirmation) goes to every account, because it is required to use the service at all.
• Advice and offer email goes only to people who ticked the separate consent box at registration. That box is optional and does not affect your access to the service.

You can withdraw consent at any time using the link at the bottom of any advice email, or by emailing us.

We do not sell your data. It is only passed to the providers the service needs to work:

• Google — Google sign-in (if you choose it) and reCAPTCHA anti-bot on the registration page.
• PayOS — processing payments in Vietnamese dong.
• Gmail SMTP — sending service email.
• DB-IP — approximate location data (country, region) derived from IP addresses.

We use no advertising cookies. Your browser stores:

• accessToken in localStorage — keeps you signed in.
• visitorId in localStorage — an anonymous id used for usage statistics.
• sessionId in sessionStorage — groups the actions of a single visit.

Clearing your browser data signs you out on that device.

Data is held in a SQL Server database over encrypted connections. Passwords are not stored in readable form. We keep your study data for as long as your account exists, so you can see your progress over time; technical activity logs are kept for statistics and abuse detection.

You can ask to see, correct or delete your data, withdraw marketing consent, or get a copy of your results. Send the request from the email address you registered with to esatprep.vietnam@gmail.com; we respond within 30 days. Note that deleting an account is irreversible and removes your entire test history.

The service is aimed at students preparing for the SAT. If you are under 16, please register with the consent of a parent or guardian. When this policy changes we update the text and the date at the top of this page; changes that materially affect your rights will also be announced by email.
