Deep Test Prep
Privacy policy
Last updated September 25, 2026
This page explains what Deep Test Prep collects when you use deeptestprep.com, why, and who helps store it. The short version: we keep what’s needed to run your account, save your progress, and process a purchase, and we never sell it.
What we collect
- Your email address, and your name and profile picture if you sign in with Google.
- Your lesson progress: which lessons you started and finished, and which practice questions you answered correctly.
- Purchase records from Stripe, such as the amount and date. Stripe handles card details, so we never see your card number.
- If you apply to be an affiliate, the details you give in the application.
Cookies and browser storage
A sign-in cookie keeps you signed in. If you arrive through an affiliate’s link, a cookie remembers that for 60 days so the affiliate gets credit for a purchase. If you aren’t signed in, your progress is kept in your own browser’s storage and is added to your account when you sign in.
Services that store data for us
Supabase stores accounts and progress, Stripe processes payments, Resend delivers email, and Vercel hosts the site. Each one handles data only to provide its service.
Students
The site is meant for students 13 and older. Parents and students can ask us to delete an account and its data at any time.
