Is Mimi Sound Personalization safe?

Low risk

Mimi Sound Personalization lets any website send messages that change its extension-wide audio settings.

The extension injects a message bridge into every frame on every website and forwards matching page messages to its background script without checking the sender origin. Those messages can change the saved mix, preset, and enabled state that the extension syncs across tabs. Its popup also embeds an OAuth client secret and sends it with token requests to Mimi's API during login and refresh flows.

Where it sends data

Destinations our analysis observed Mimi Sound Personalization contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
