The full TrackLode Privacy Policy is at https://tracklode.com/privacy (section 13 covers this extension).

In short: the extension stores your access token, the TrackLode address and your last chosen project in this browser profile, and your last known timer and Focus status and project list for the current browser session only. It sends data only to https://tracklode.com over HTTPS, with your token in the request header: it reads your timer and Focus status and your projects, starts and stops the timer with the project and any note you add, controls Focus and changes your Focus settings. It doesn't read the pages you visit, your tabs or your browsing history, has no analytics or advertising, contacts no other service and runs no remote code. Remove the token in the extension's settings, revoke it in TrackLode under Settings > Browser extension, or remove the extension to delete what it stored.
