Absolutely everything.

This includes your website list, pause times, schedules, preferences, and statistics.

The statistics only keep track of counts and durations. They don’t save any page content or web addresses.

TOCus works entirely offline and doesn’t track your data on your device.

If you pause while on a website, the address might be saved for a short time so you can go back to it.

You don’t have to just take my word for it. The source code is available on GitHub if you want to check for yourself.


TOCus needs access to the websites you choose so it can show the pause. You control which sites to allow.

When you click the toolbar icon, TOCus gets access to the website you’re currently visiting, but only for a short time, and doesn’t send that data anywhere.

“Navigation access” lets TOCus see changes to websites as they happen, but it doesn’t look at your saved browsing history.

TOCus saves your choices using local storage. It uses scripts and browser rules to show the pause, and alarms to keep the timing correct.

Your browser tries to use website icons from its own cache whenever it can. Sometimes this doesn’t work. I set it up this way to keep TOCus completely private and avoid connecting to any icon service.

If TOCus doesn’t have access to a website, it can’t pause that site. You can update these permissions in your browser’s extension settings.


“Reset statistics” deletes recorded counts and total time while keeping your sites and settings. “Reset all TOCus data” deletes sites, schedules, timing, preferences, active pauses, and statistics, removes allowed website access, and restarts setup.

After a reset, TOCus may keep a random value in local storage so an old settings page can’t bring back deleted data. The value shows that a reset happened. It doesn’t identify a person, device, account, or browsing activity.
