Information processed on your device
On x.com and twitter.com, the extension reads the page structure X has already rendered in your browser so it can hide, restore, restyle, or add the features you selected. Depending on those settings, locally processed information can include visible post structure, account display names and handles, post links and timestamps, visible menu labels and states, and interface elements such as timelines, navigation, metrics, media warnings, and dialogs.
If you click an inline Mute or Block control, the extension uses the visible account identity and X's own rendered menu and confirmation controls to verify the target and perform the action. It does not call X's private authenticated APIs or read or retain authentication-token or cookie values. Targeted X requests keep their original credentials when they continue to the same X endpoint.
How settings reach the feature engine
The feature engine runs in the X page context so it can work with X's rendered controls. At startup, the content script places the current configuration in a short-lived page element; the feature engine reads it and immediately removes that element. Later changes use same-page messages. This processing stays inside the current browser page, although values present in the page context can technically be observed by code running on that X page.
Information stored on your device
chrome.storage.local stores feature preferences, custom CSS, and optional diagnostic configuration. If you use Quote Tweet muting, it also stores the quoted account's displayed name and post timestamp, plus account handles you choose to suppress quotes from. The current version does not retain quote text; upgrades remove quote text saved by older versions.
Two boolean values—whether the extension is enabled and whether you opted into older Twitter branding—are also mirrored ascpftEnabled and cpftReplaceLogo in X's origin-scoped localStorage. They let document-start branding behavior avoid a visible flash. They contain no account identifier or page content, but X page scripts can access them because they are stored in the X site context. These two values can remain until X site data is cleared or a later setting change overwrites them; uninstalling the extension does not necessarily remove site-origin storage.
Extension storage remains in your Chrome profile until you change or reset settings, clear extension data, or uninstall the extension. The Export configuration control creates a local file only when you explicitly select it. You decide whether to share that file.
Where information goes
Ultimate X Control Panel has no developer-operated backend and does not transmit page content, settings, local records, or usage data to the publisher. It does not sell personal data, use it for advertising or analytics, share it with data brokers, or transfer it for unrelated purposes. It contains no analytics, telemetry, tracking SDK, or remotely hosted executable code.
X/Twitter receives your normal site activity and any mute, block, or other interaction carried out through its own visible controls, just as it would if you used those controls without the extension. That activity is governed by X's own terms and privacy practices.
The extension's use of information is limited to providing or improving the requested user-facing features and complies with the Chrome Web Store User Data Policy, including its Limited Use requirements.
Information not read, retained, or transmitted
The extension does not read, retain, or transmit:
- password, authentication-token, or cookie values;
- direct-message contents;
- browsing history outside the X/Twitter pages where it runs;
- precise location, financial or health information, or government identifiers;
- analytics, advertising identifiers, or usage telemetry.
Permissions
storagesaves the extension preferences and local records described above.- Access to
x.com,mobile.x.com,twitter.com, andmobile.twitter.comlets the extension apply selected controls and inline actions only on those sites.
No broad all-sites, cookies, tabs, history, identity, downloads, webRequest, or scripting permission is requested.
Security and your choices
All executable code ships with the extension. You can pause the extension, disable individual features, use section resets, clear Chrome extension data, clear X site data, disable the extension, or uninstall it. Blocking asks for confirmation by default, and mute fails without acting when the visible target or state cannot be verified.
Children and policy changes
Ultimate X Control Panel is not directed to children under 13 and does not knowingly collect information from children. If this policy changes materially, this page and the Chrome Web Store disclosures will be updated before the new practice takes effect.
