YouTube Playlist Search Privacy Policy

Last updated: April 15, 2026

Overview

YouTube Playlist Search is a Chrome extension that adds an in-page search bar to YouTube's playlist selection interfaces. It fetches your playlists directly from YouTube and lets you save videos to them.

Data Collection

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 developer does not operate a backend server and never receives any of your data.

No personally identifying information is ever read, stored, or transmitted. Your username, email, and profile photo are ignored by the extension.

External Services

The extension only communicates with youtube.com — the same server you are already browsing. It does this by calling YouTube's internal "InnerTube" API (https://www.youtube.com/youtubei/v1/*) as a same-origin request from the YouTube tab you already have open. No requests are made to any other server, and no data is sent to the extension developer.

Authentication

The extension does not use OAuth, does not use chrome.identity, and does not obtain, store, or transmit any access tokens or refresh tokens.

Because InnerTube requests originate from a youtube.com page, your browser automatically attaches your existing YouTube session cookie — the same way it does when you click around YouTube normally. To satisfy InnerTube's authentication scheme, the extension reads the SAPISID cookie from document.cookie on the current YouTube tab and uses it to compute a short-lived SAPISIDHASH authentication header. The cookie value and the derived hash are only ever sent back to youtube.com itself as part of these same-origin API calls. They are never stored, logged, or transmitted anywhere else.

Local Processing and Storage

The extension reads the following "website content" from the YouTube pages you visit:

This data is indexed locally in your browser using MiniSearch so you can type-ahead search your playlists. The index lives only in the tab's memory — the extension does not use chrome.storage, localStorage, cookies, or any other persistent storage. A short (6-hour) in-memory cache of your playlist list may be kept while the tab is open; it is cleared when the tab closes.

All search, ranking, and filtering is performed locally in your browser.

Permissions

The extension requests no Chrome API permissions (the permissions array in manifest.json is empty). Its only site access is a content script injected into https://www.youtube.com/* — the single host it needs in order to place a search bar inside YouTube's save-to-playlist dialog and playlist feed. It does not run on any other site, subdomain, or scheme. There is no background service worker and no popup.

Third-Party Code

The extension bundles a local copy of MiniSearch for BM25-based ranking. MiniSearch runs entirely in your browser; no remote executable code is loaded at runtime, and no third-party SDKs are used.

Changes

If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
