Auto Sponsor Skipper — Privacy Policy

Last updated: 6 July 2026

Auto Sponsor Skipper is a Chrome extension that automatically skips community-submitted segments on YouTube. It is built to need as little of your data as possible. This page explains exactly what it does and does not do with data.

The short version

No accounts, no sign-up, no analytics, no tracking, no advertising.
We operate no servers of our own and never sell or share your data.
The only thing ever sent off your device is a 4-character hashed prefix of the video ID, sent to SponsorBlock to look up skip segments.

What is sent to SponsorBlock

To find skip segments for the video you are watching, the extension computes a SHA-256 hash of the YouTube video ID and sends only the first 4 hexadecimal characters of that hash to the SponsorBlock API at https://sponsor.ajay.app over HTTPS. It receives candidate segments for many videos and filters them locally.

The full video ID never leaves your browser. A 4-character prefix is k-anonymous: it matches thousands of different videos (about 1 in 65,536 of the hash space), so SponsorBlock cannot determine which video you are watching. No user identifier, cookie, or account is attached to the request.

What is stored, and where

Settings (which categories to skip, minimum segment length) are stored in chrome.storage.sync. If you have Chrome Sync enabled, Chrome syncs them across your signed-in browsers; otherwise they stay on this device. This is handled by Chrome, not by us.
The segment cache, statistics, and the channel whitelist are stored in chrome.storage.local and stay on this device only — they are never transmitted.

Data retention and deletion

Cached segments expire automatically (about 7 days for found segments, 90 seconds when a video has none, 30 seconds after a lookup error) and the cache is capped in size, oldest entries pruned first.
You can reset the statistics at any time from the extension's options page, and remove any channel from the whitelist there.
Uninstalling the extension removes all of its local data from your browser.

Third parties

The extension contacts exactly one third-party service: the SponsorBlock API, and only to fetch skip-segment data as described above. No other network requests are made. No data is sold or shared with anyone.

Google API Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
