# Privacy Policy **Last updated:** July 4, 2026 ## Data Collection De-Mainstream YouTube Extension **does not collect, store, or transmit any personal data, usage data, or any other information** from its users. ## How It Works - All group toggle preferences (which mainstream channels you choose to hide) are stored **locally** in your browser using `chrome.storage.local`. - No data is ever sent to external servers, APIs, or third parties. - The extension only runs on `https://*.youtube.com/*` pages and has no network access beyond what is required to function as a YouTube content filter. ## Third-Party Services This extension does not integrate with any third-party analytics, tracking, or advertising services. ## Changes If this policy changes, the updated date at the top will be revised. Since we do not collect data, no notification of changes is necessary. ## Contact For questions about this privacy policy, open an issue on the [GitHub repository](https://github.com/ashleyjackson/De-Mainstream-YouTube-Extension/issues).
