ToggleMark does not collect, store, transmit, or share any personal or browsing data.

All bookmark operations are performed locally on the user’s device using Firefox’s built-in bookmarks system. No information is sent to external servers, and no analytics, tracking, or telemetry is used.

The extension does not access, process, or retain any personally identifiable information. All functionality operates entirely within the local Firefox browser environment.

If you uninstall the extension, no data remains stored by ToggleMark.
