The extension only performs the functionality described in the Chrome Web Store listing and operates within the browser environment.

Ultimate Brightness Control uses Chrome's built-in storage API to save your preferences — global brightness level, per-site overrides, and whether the extension is enabled. This data never leaves your browser and is never transmitted to any server.
This extension does not use third-party analytics, tracking services, or external data collection tools.
If you reach out for support, we use the information you voluntarily share only to respond to your request. We don't store it beyond that conversation.
The developer may update this Privacy Policy from time to time. Any changes will be reflected on this page. Continued use of the extension after changes are posted means you accept the revised policy.
