SentiaRead Browser Extension Privacy

Reader Mode extracts and renders articles locally. Reading preferences, authentication sessions and vocabulary cache are stored in the browser.

An account is used for authentication and cross-device vocabulary sync. AI lookup, translation, sentence simplification and text-to-speech send selected text to SentiaRead only when you request these features. Lookup and saved vocabulary contexts may include the source page URL and title. Vocabulary sync runs at browser startup, when Reader Mode opens, and after word changes. We do not collect a browsing-history list.

The service uses the IP address to infer a coarse country code for service routing; it does not request or store precise location.

Error reports and usage analytics are sent only if you allow Firefox optional technical and interaction data. Signed-in error reports go to Sentry and usage analytics go to PostHog, linked to account ID. These reports exclude lookup text, page content, page URLs and titles, email and name. Signed-out use sends neither, except that an automatic sign-out can send a diagnostic report linked to the last signed-in account ID. Signing out yourself removes that ID.

We do not sell personal data. We use it to provide the requested reading and vocabulary features, authentication, synchronization and reliability improvements.
