This version doesn't track or send any data to remote server. Hence no privacy policy or user privacy control is needed.

Only information it stores is extension settings which user changes in options page.

The source contains references to google analytics because same code is used for chrome version of extension also which uses google analytics. To prevent loading Google analytics, a condition is added to not load google analytics script for firefox/mozilla and google url is not present in content_security policy of manifest file, which prevent it from loading google analytics script. Since google url is also not present in content-scripts section of manifest, extension can't make any API calls to google analytics.
