Privacy Policy

Last Updated: March 20, 2026

Data Collection

This extension does not sell personal data and does not use third-party analytics, advertising, or telemetry SDKs. Extension feature data and user preferences are stored locally in your browser using Chrome's storage API and remain on your device.

We do not collect user data for profiling or marketing purposes. If data practices ever change, this policy will be updated before any new collection begins.

How It Works

This extension works on YouTube pages in your browser and applies user-selected modules such as Discovery, Quality Settings, Focus, and Looper. Core settings are processed locally inside the extension runtime.

Network Requests

The extension communicates only with required domains declared in the extension manifest:

https://www.youtube.com/*: YouTube page integration and feature behavior on watch/home experiences.

https://music.youtube.com/*: Looper behavior support on YouTube Music pages.

https://us-central1-vivies-toolkit-for.cloudfunctions.net/*: Discovery proxy requests used to fetch trending feed data (for example mode, country/category filters, cursor, and result size).

No third-party ad or analytics endpoints are used by the extension.

Third-Party Services

This extension does not use third-party analytics, tracking, advertising, or data broker services.
