Privacy Policy — X History

Last updated: 2026-07-31 · Browser extension for x.com / twitter.com

Summary: X History stores your post history on your device. By default it does not upload your history, does not require an account, and does not include third-party analytics.

1. Who we are

“X History” is a browser extension that keeps a local history of posts you open or interact with on the X (Twitter) website. This policy describes how the extension handles information when you use it.

2. Information we process

The extension may store the following locally in your browser (chrome.storage.local):

Items may be recorded when you open a post detail page, when you use on-page actions such as like / repost / reply / bookmark, or when you carefully read a post in the timeline under conservative focus rules. Data is read from the X page you are viewing. It is not collected from other websites.

3. How we use information

4. Data storage and transmission

5. Permissions

6. Third parties

The extension does not embed third-party analytics or advertising SDKs. When you use X, X’s own privacy policy applies to your activity on their service.

Avatar images may be loaded from X’s image hosts (e.g. twimg) when displayed in the history list; that request is made by your browser to those hosts.

7. Data retention and deletion

8. Children’s privacy

The extension is not directed at children under 13. Do not use it if you are not permitted to use X under applicable rules.

9. Changes

We may update this policy when features change. The “Last updated” date at the top will be revised accordingly.

10. Contact

For privacy questions, contact the publisher email listed on the Chrome Web Store listing for “X History”, or open an issue on the project’s public repository if available.
