On the Sofa for YouTube
Last updated: June 5, 2026

This Privacy Policy describes how the Chrome extension On the Sofa for YouTube (“the Extension,” “we,” “us”) handles information. The Extension is an unofficial third-party tool for YouTube. It is not affiliated with, endorsed by, or sponsored by Google or YouTube.

1. Summary

2. Information stored on your device

The Extension uses Chrome’s storage API (sync storage) to save:

This data stays on your device and in your Chrome sync account if you use Chrome Sync. We do not operate a backend database that stores this information.

3. Information sent to third parties

3.1 Lemon Squeezy (Pro licenses)

If you purchase Pro or enter a license key, the Extension sends requests to Lemon Squeezy’s License API (api.lemonsqueezy.com), including:

Payment processing, billing, and refunds are handled by Lemon Squeezy as Merchant of Record. Their privacy practices are described in Lemon Squeezy’s Privacy Policy.

3.2 YouTube (google.com / youtube.com)

The Extension injects a user interface on YouTube pages and reads the page DOM locally to position controls and detect the video player. No YouTube viewing data is sent to us. Your use of YouTube remains subject to Google’s Privacy Policy.

4. Permissions and why they are used

5. Data we do not collect

6. Children’s privacy

The Extension is not directed at children under 13 (or the applicable age in your region). We do not knowingly collect personal information from children.

7. Data retention and deletion

Data in Chrome storage remains until you uninstall the Extension, clear extension data in Chrome settings, or deactivate your license in the Extension popup. Uninstalling the Extension removes locally stored extension data from your browser profile.

8. International users

Lemon Squeezy may process payment and license data in accordance with its own policies and applicable law. The Extension itself does not transfer your YouTube activity to our servers.

9. Changes to this policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will be revised when changes are made. Continued use of the Extension after changes constitutes acceptance of the updated policy.
