Privacy

Nothing you do here is uploaded — there's nowhere for it to go, and no account for it to be attached to.

What is stored, and where

Your intervals, watcher settings and the last alert are kept in the browser’s own extension storage, on your machine. Uninstalling the extension removes them.

What is read

When you start a timer on a site, Chrome asks whether to grant access to it. With that access the extension does two things: it draws the countdown on the page, and — if you turned the watcher on — it reads the page’s visible text to compare it with the previous check.

That comparison happens inside your browser. The extension keeps a short excerpt (up to about 2,000 characters) around the match so it can show you what changed. That excerpt lives in local storage and is replaced on the next check.

What is never done

No network requests. The extension has no endpoint to call.
No analytics, telemetry, crash reporting or usage counters.
No account, sign-in, sync or device identifier.
It never reads a page you haven't started a timer on.
Nothing is sold or shared, because nothing is collected.
