None. The YT Channel Blocker extension does not collect, store, transmit, or share any user data of any kind.
When you visit youtube.com, the extension injects a single button into the page. When you click that button, the extension iterates over the YouTube video tiles currently visible in the page's DOM and triggers YouTube's own built-in “Don't recommend channel” action on each one.
All processing happens locally in your browser. No information is sent to any server operated by us or any third party.
The extension requests access only to https://www.youtube.com/*. This is the minimum required to inject the button on YouTube pages. The extension does not run on, request access to, or interact with any other website.
The extension does not use any third-party services, analytics, telemetry, advertising networks, remote APIs, or external scripts.
If this policy ever changes (for example if a future version of the extension introduces new functionality), the updated policy will be published at this same URL with a revised effective date.
