YouTube Auto Liker is designed to run locally in the browser and automate liking behavior on YouTube according to the user's settings.


The extension stores the following information using browser extension storage:

• Whether automatic liking is enabled.
• Timing and watched-percentage settings.
• Subscription and advertisement-waiting preferences.
• Channel allow-list and do-not-like-list settings.
• User interface preferences.
• Optional activity history.

Activity history is disabled by default. If enabled, recent automatic-like activity is stored locally in browser extension storage.


The Firefox version does not initialize Sentry or transmit diagnostics, settings, activity history, YouTube activity, or personal information to the developer or any external analytics service.

The extension does not sell, share, or otherwise provide user data to third parties.


The extension runs on https://www.youtube.com/* to:

• Detect the current video and channel.
• Check whether advertisements are playing.
• Check subscription state when the subscribed-only option is enabled.
• Read the state of the Like and Dislike controls.
• Click the Like button when the user's configured rules are satisfied.

This access is used only to provide the extension's requested functionality.
