Privacy policy

Your EPUB, filename, contents, metadata, findings and corrected output stay in your browser. They are never uploaded or sent to analytics. Session data clears on reset or page exit. Temporary download URLs are revoked after use.

Optional Google Analytics

GA4 runs only after Accept analytics, based on consent (GDPR Art. 6(1)(a)). It counts page views and tool starts/completions. page_view includes the page path; tool events include only fixed names, tool ID, hostname and success. Google receives network/device data, sets analytics cookies after consent, and may process data outside the EU.

The consent choice stays in device localStorage for 180 days. Analytics cookies have a configured 180-day lifetime. Google Analytics keeps event and user data for 2 months. Withdraw through Analytics preferences or Reject / withdraw analytics. Withdrawal does not affect prior lawful processing.

Hosting

Netlify decides how long it keeps its hosting logs; it does not publish a fixed period. See Netlify's privacy policy, or ask Netlify for the current period. Netlify may log IP addresses and requested pages for hosting/security. Book files are not included. There are no accounts, ads or server-side book processing.
