Miru collects no data. Every feature works locally in the browser: no servers, no analytics, no tracking, no remote code, no cookies. Nothing is ever transmitted to the developer or any third party.

If you enable Firefox Sync, your settings sync across your own devices through your browser (Mozilla), never through us. Per-site time totals stay on your device and are deleted after 14 days.
