Studytracker keeps only what it needs to help you learn. Here is what that is, who helps run the site, and how to take your data with you or remove it.
What we keep
Your email from signing in; what you create: materials, notes, drawings, questions, dictionaries, attempts and review history; and your settings such as time zone and languages. Nobody else sees your materials unless you share a link or publish to the library.
Visit statistics
Only if you allow it, Google Analytics counts which pages are opened, from what kind of device and roughly from which country. Shared links are sent without their secret part, and nothing that names you is sent. Advertising features are off. You can change your choice at any time with “Cookies” at the bottom of the page.
Errors and speed
When something breaks, technical details of the error go to Sentry (servers in the EU) so we can fix it. Vercel Speed Insights measures how fast pages load, without cookies and without identifying you.
AI features
When you use an AI feature, the text it needs (for example a material's content or your answer) is sent to the AI provider for that one request: Anthropic, OpenAI or Google.
Who helps run the site
Supabase (sign-in), Microsoft Azure (server and database), Vercel (website), Resend (emails), Sentry (error reports), Google (visit statistics, only with consent), Stripe (payments, only if you buy a plan; we never see card details) and the AI providers above.
Your data, your choice
On the Account page you can download everything we keep about you or delete your account for good. Reminder emails can be turned off in the statistics page settings.
