Privacy & licensing

Privacy

This application does not use accounts. Your saved progress is stored in IndexedDB in this browser.

While you review a session, a pasted tutor response is held only in the page's transient form state; it is not stored in IndexedDB.

Downloaded backups are files you manage; they are not stored in IndexedDB by this application.

Application code does not transmit progress, pasted tutor responses, imports, or backups. There are no analytics, telemetry, advertising, or tracking.

Vercel receives ordinary requests for the public application, content, media, and attribution files. External chat is separate from this application and follows the privacy terms of the chat service you choose.

This application does not guarantee offline use: public app files, content, media, and attribution can be requested when needed. You are responsible for keeping any backup you want to retain.

Licensing

Application code is licensed under MIT.

Project-authored prompts, lessons, curricula, exercises, and content documentation are licensed under CC BY-SA 4.0.

Third-party media keeps the licence recorded for that individual media item; it does not inherit the project content licence. Read media attributions.

These project licence claims do not license learning-material, confidential DUO material, or other third-party material.
