YouTube Playlist Filter is a Chrome extension that adds an in-page search bar to YouTube's playlist selection interfaces. It also uses the YouTube Data API to fetch your playlist names and save videos to your playlists.
This extension does not collect, store, transmit, or sell personal data to the extension developer or any third party. No analytics, tracking, or remote logging is performed.
The extension communicates with the following Google services and no other external servers:
googleapis.com — to call the YouTube Data API
(playlists.list for fetching playlist names,
playlistItems.insert for saving videos to playlists)oauth2.googleapis.com — to handle OAuth 2.0 authentication and
token refreshThese requests are made directly from your browser to Google. The extension developer does not operate any intermediate servers and never receives your data.
When you sign in, OAuth tokens (access token and refresh token) are stored locally in
chrome.storage on your device. These tokens are used solely to authenticate
YouTube Data API requests and are never transmitted to the extension developer or any
server other than Google's OAuth and API endpoints listed above.
The extension runs as a content script on youtube.com pages and uses a background
service worker to manage API calls and token storage. Playlist filtering is performed locally
in your browser.
The extension bundles a local copy of MiniSearch for BM25-based ranking. No remote executable code is loaded at runtime.
If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
