Joining the beta list
When you submit the signup form, we store your email address and the time you joined in Cloudflare D1. We use this list to contact you about a beta invitation. It does not create a study account.
Cloudflare hosts the site and provides Turnstile to check for automated submissions. The signup endpoint uses your IP address for rate limiting and bot verification; it does not save that address in the waitlist table. Cloudflare may process technical information to deliver and protect these services. Read Cloudflare's privacy policy.
Earlier waitlist submissions were collected through LaunchList and may still be held there. New submissions on this site go directly to Restudium's Cloudflare-hosted endpoint.
Using the private app
The invite-only app uses your sign-in identity to keep study progress separate. It stores your answers' self-assessed grades, review schedule and chapter progress. Optional reminder settings and device subscriptions support study notifications. Draft recall text may be kept in your browser so you can return to a sitting.
Course preparation uses OpenAI for authoring. The public signup form does not send your email to a model or accept book uploads.
Your choices
Contact hello@restudium.com to ask about your information, correct it, or request removal from the beta list or deletion of your study data. You can also use an unsubscribe option provided in an invitation email.
The sample lesson on the public homepage does not save your answer. Clearing site storage removes locally held drafts and settings, but does not delete server-side study progress.
