Xnnoying ("the Extension") is a Chrome extension that adds quick block and mute buttons directly on tweets on x.com and twitter.com. This privacy policy describes what data the Extension accesses, how it is used, and how it is protected.
The Extension accesses the following data while you use x.com or twitter.com:
Authentication cookie: The Extension reads your existing session cookie (ct0 CSRF token) from the browser to authenticate block and mute requests with X's API on your behalf.
Website content: The Extension reads usernames (screen names) from the tweet elements displayed on the page to identify which account to block or mute when you click a button.
All accessed data is used solely to perform the block or mute action you initiate. Specifically:
Your CSRF token is included in the request headers sent to X's own API endpoints (blocks/create and mutes/users/create) so the action is performed under your authenticated session.
The screen name is included in the request body sent to those same X API endpoints.
Data is used transiently at the moment you click a button. The Extension does not store, cache, or persist any of this data.
The Extension does not transmit any data to the developer or to any third-party server. All network requests are sent exclusively to X's own API on the same domain you are already browsing (x.com). No data is sold, shared, or transferred to any third party.
All requests to X's API are made over HTTPS. The Extension does not store any user data locally or remotely.
The Extension requires host access to x.com and twitter.com only. It uses no other browser permissions and has no background scripts, analytics, or tracking of any kind.
The Extension's use of data received from X complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. The Extension only uses data to provide its core blocking and muting functionality and does not use or transfer data for advertising, creditworthiness, or any unrelated purpose.
If this policy is updated, the revised version will be posted on this page with an updated date.
If you have questions about this privacy policy, you can reach the developer through the Extension's support page on the Chrome Web Store.
