Last updated: 2026-06-18

By using Hummo (the "Service"), you are deemed to agree to these Terms.

1. Nature of the Service (demo / beta)

The Service is currently a Chrome browser extension in a demo/beta stage. Its features, availability, and policies may change or be discontinued without prior notice, and we provide no guarantee that any data will be preserved.

2. Music playback and copyright

The Service does not stream or redistribute audio. All music plays locally on your own device through your own YouTube Music account, and the Service only syncs playback state (the track identifier, playback position, whether it is playing, and a timestamp).

3. Accounts and rules of use

4. Fees and subscription

Free — up to 3 people per room.

Pro — $2.99/month — unlimited simultaneous listeners (4 and up).

5. Disclaimer and limitation of liability

The Service is provided "AS IS". The Service does not warrant the accuracy of synchronization, uninterrupted availability, or fitness for a particular purpose. To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the Service. You are responsible for your YouTube Music account, playback, and use of content.

6. Changes to these Terms

These Terms may change. When they do, the last-updated date on this page will be revised. If you continue to use the Service after a change, you are deemed to have agreed to the revised Terms.

7. Governing law

These Terms are interpreted and applied in accordance with the laws of the Republic of Korea. Where mandatory consumer-protection rules apply, those rules take precedence.
