Device storage & cookies

Device Storage & Cookies Notice · Version 2026-08-08 · Effective 8 August 2026.

No advertising trackers: Chapbook does not use behavioural advertising, third-party analytics pixels or social tracking cookies. It uses first-party device storage to provide the local/offline application you request.

What is stored

Why no cookie banner appears

These stores are required to provide the requested local/offline app, remember user-requested choices, authenticate an optional connection or secure a session. They are not used for cross-site tracking. Where storage law treats them as strictly necessary, a separate opt-in is not required, but this notice remains available. Any future non-essential analytics/advertising storage must stay off until valid consent is obtained.

Control and deletion

Export before clearing data. Use Settings → Sign out & forget this device, clear browser site data or uninstall. Revoke credentials at GitHub, the AI provider or Cloudflare after a lost/shared device. Clearing Chapbook does not delete published repositories/R2 media or necessarily revoke a remote token.
