Information we collect

When you visit this website, your browser stores an anonymous guest ID and your language preference in local storage. Temporary access tokens are used when calling room and plaza APIs. We do not collect personal identity information such as your name, email or phone number.

How we use information

The guest ID identifies you within the demo pages; language preference controls the UI language; access tokens are used only to communicate with content services and are not stored on our servers.

Third-party services

Room and song content is provided by third-party services. Links to the App Store and Google Play are handled by those platforms under their own privacy policies.

Storage and deletion

The data above is stored only in your browser’s local storage. Clearing your browser data removes it. We do not store, sell or use your personal information for ad tracking.
