Privacy Policy
Last updated October 3, 2026
- Xifex has no server. It does not collect, sell, share or transmit your data.
- It works inside the X tab you already have open, using your existing sign-in. It never reads your cookies or passwords.
- Only your saved filters and one on/off setting are stored, locally in your browser.
What Xifex is
Xifex is a browser extension for x.com. It labels posts in your For You feed with whether their author follows you, and adds search and filters to your own Followers, Verified followers and Following lists.
Data Xifex handles
To do this, Xifex reads public account details that the X page has loaded: names, handles, bios, profile pictures, follower and following counts, verification, and whether an account follows you or you follow it. This information is held in your browser's memory for the open tab only. It is discarded when you reload the page, switch accounts or close the tab.
Data Xifex stores
Xifex stores two things in your browser's extension storage, on your device only:
- Filters you choose to save, with their names and conditions, kept separately for each signed-in X account.
- Whether follow status labels are turned on.
You can delete saved filters in Xifex, or remove everything by clearing the extension's data or uninstalling it.
Requests Xifex makes
Xifex talks only to x.com, using the session already signed in to your browser. When you open Filter, it reads further pages of your own list by repeating the read-only list request the X page made. When a post author's follow status is missing from the feed, it makes one read-only profile request for that author, limited to about 30 per minute. Xifex does not have its own login, does not use an API key, and does not extract or store session tokens. X's own privacy policy applies to these requests.
Actions on your behalf
Xifex never follows or unfollows anyone by itself. When you choose to unfollow an account, it opens X's own confirmation for that single account, and X performs the action only if you confirm.
What Xifex does not do
- No analytics, telemetry, advertising or tracking.
- No sale or transfer of data to third parties.
- No use of data for anything other than the features described above, and none for creditworthiness or lending.
- No remote code: all code ships inside the extension package.
Permissions
- storage: saves your filters and the on/off setting locally.
- contextMenus: adds the on/off checkbox to the toolbar icon's right-click menu.
- Access to x.com: runs Xifex's features on X pages only.
Changes
If this policy changes, the new version will be posted on this page with a new date.
