Information used to run your account

Firebase Authentication handles email/password sign-in, email verification and password resets. The application uses verified Firebase identity information to associate you with your learner account.

Our PostgreSQL database stores learner records, question attempts, results, bookmarks, progress and access grants. If you choose to link Telegram, we use your Telegram identity to connect your learning activity across the website and bot.

Browser storage and infrastructure

Firebase uses browser storage to maintain sign-in. The application also uses browser state for its interface and authentication flows. Website requests pass through Cloudflare Tunnel to the operator’s server. Operational logs and database backups support troubleshooting and recovery.

Payments

Payment and transaction information is used to process purchases, confirm access and resolve payment issues. Card credentials should only be entered in the payment provider’s checkout.

Your requests

You may request assistance with your data or account through the contact form. Identity verification may be required.
