Information we store
Account details, saved lessons, private collections, teacher-authored worksheet text, lesson progress, quiz history, forum contributions, and messages you send are stored only to provide those features. Passwords are stored as secure one-way hashes; payment proof images remain outside the public document root.
Cookies and optional services
A Secure, HttpOnly session cookie is used when you sign in. Optional analytics or advertising services remain disabled until you choose to allow them, and the preference is stored locally in your browser. AI learning requests are sent through our server with a pseudonymous safety identifier and are requested with provider storage disabled.
Your choices
Collections and worksheet text are private by default. If you confirm sharing, anyone with your unlisted link can read the shared worksheet for 30 days. Links can be replaced or revoked; downloaded or printed copies cannot be recalled. The shared page shows no account identity or learning progress. You can keep optional services off, use the public library without an account, and contact us about access to or deletion of your account data.
Availability
Features may change as the library evolves. We may limit abusive use or remove content that creates safety, legal, or reliability problems.
