YouTube Activity Cleaner

Last updated: April 16, 2026

YouTube Activity Cleaner is designed to run locally in your browser. The extension helps you automate repetitive cleanup actions for your own signed-in Google account on supported Google My Activity pages and on the YouTube Liked videos playlist page.

What Data The Extension Accesses

The extension reads and interacts with supported Google My Activity pages at https://myactivity.google.com/* so it can find visible remove controls, item rows, and status messages for comments, comment likes, live chat history, and community posts.
The extension also reads and interacts with the YouTube Liked videos playlist page at https://www.youtube.com/playlist?list=LL so it can trigger the visible remove action there.
The extension stores your cleaner preferences locally in Chrome, such as pacing, retry count, and failure limits.
The extension uses the Chrome tabs and power APIs to open supported cleanup pages, track the active cleaner tab, and request keep-awake while a run is active.

What Data We Do Not Collect

We do not collect, transmit, sell, or share your browsing history, activity content, account credentials, or personal data with external servers.
We do not send your data to analytics, ads, or third-party tracking systems.
We do not use remote code execution or fetch external scripts to operate the extension.

Where Data Is Stored

Cleaner settings are stored locally in Chrome storage on your device. Session information about the currently attached cleaner tab may also be stored in browser session storage so the popup can reconnect to the current run. The extension does not maintain any remote database of your YouTube activity.
