Cookies & browser storage

Essential local storage

ReadFlow uses local storage for reading records and settings (rf_progress_v1), theme preference (rf-theme), and your optional analytics choice (rf_analytics_consent_v1). Local storage is different from cookies: it remains in your browser and is not automatically attached to ordinary website requests. The offline service worker may cache application files and topic JSON on this device.

Optional analytics cookies

If Google Analytics is configured and you allow it, Google may set first-party analytics cookies such as _ga and _ga_<identifier> to recognise visits and measure usage. Their lifetime is controlled by the Analytics configuration. They are not required to read topics or save progress.

ReadFlow waits for permission before loading the Google tag. Choosing Decline analytics keeps the reading website functional. You can change the choice below or through Cookie settings in the footer.

Removing saved information

Use your browser’s site-data controls to remove local storage, cached offline files and cookies for readflow.mizahub.com. Clearing site data also removes your reading progress and preferences. Withdrawing analytics permission removes accessible Google Analytics cookies for this site and stops further collection through this integration. Last updated: 14 November 2026.
