Guest access
The learning app saves drafts, answers, attempts, review history and video positions in your browser. Clearing browser storage removes local copies. Each browser and website address has separate storage.
Optional email sign-in
When email sign-in is enabled, Supabase stores your email, account and a cloud copy of your learning record. This includes written answers, notes, attempts, review history and video positions. Sign in with the same email on another device to continue. Study preferences remain separate on each device.
Guest work is added to an account only when you choose “Add this device’s guest progress.” Wait for the account page to confirm syncing before changing devices or site addresses. Signing out restores this browser’s guest workspace and keeps a local account copy for your next sign-in.
Video pages and practice
You can read lessons and watch videos on the course website. Saved video positions, lesson attempts and review activities are available inside the learning app.
Data used to run the service
The app uses no advertising or analytics trackers. Cloudflare processes hosting and technical request data. Supabase handles accounts and progress. Resend delivers sign-in emails. Written answers are stored for your learning record; assessment uses predefined answers in the app.
Protecting your work
Use a personal browser for private written work. The account page reports whether progress has synced or is waiting for a connection. Avoid including confidential information in lesson answers.
