xGhost is a Chrome extension that detects which X accounts stopped following you. This page explains what data it uses, where that data stays, and what it never does with it.

In short

• No server, no xGhost account, no analytics, no telemetry, no ads.
• All data stays in your browser. It is never sold, shared or sent to anyone.
• Uninstalling the extension deletes all of its data.

Data used and stored

xGhost stores the following only in your browser's local storage (chrome.storage.local):

• your settings (check frequency, alerts, charts shown);
• the X accounts you track with xGhost: ID, @handle, name, profile picture URL and the follower count announced by X;
• your follower list: ID, @handle, name and profile picture URL of each follower;
• the history of unfollows and new followers, and the follower count recorded each day.

x.com cookies

xGhost reads the x.com session cookies locally (auth_token, ct0, twid) only to know whether you are signed in to X and with which account. Only your account ID is kept. No cookie value is stored, logged or transmitted.

Connections

xGhost does not connect to any server of its own. To read your follower list, it opens x.com in a pinned tab, scrolls the list, then closes the tab. It reads the responses the x.com page itself receives, with your own session: it sends no requests of its own and uses no API.

When an account stops following you, xGhost also opens its profile in that tab to see whether you still follow it ("follow-back"). It reads the response x.com receives, then closes the tab. Departures are checked in small, spaced-out batches.

Profile pictures are loaded from X's image servers (pbs.twimg.com, abs.twimg.com), which therefore see your IP address, just as when you browse x.com.

Backup

The "Export my data" feature creates a file on your computer containing your follower list and history. xGhost never sends it anywhere. Keep it to yourself.

Report a bug

The "Report a bug" link opens a pre-filled GitHub page with the xGhost version and your browser name. Nothing is sent unless you submit the report on GitHub yourself.

Deleting your data

• "Remove this account", in the xGhost settings, deletes the data of one account.
• Uninstalling the extension deletes all of its data.

Limited use

The data is used only for the extension's single purpose: showing you who stopped following you on X and notifying you. It is never sold, transferred to third parties, or used for advertising or creditworthiness. Nobody reads it, since it never leaves your browser.
