Privacy
There are no ads, product analytics or behavioral tracking. Settings, queue state and the Last.fm session key are stored in Firefox extension storage. The YM Bridge service provides Last.fm application configuration, authenticates supported extension builds and provides user-initiated authentication fallback and optional Cloud relay.

If the user chooses username-or-email and password sign-in, those credentials are sent over HTTPS through the YM Bridge service only after the user presses Sign in and solely to obtain a Last.fm session key. The password is not stored.

Cloud relay is selected by default as a fallback but starts only after a one-time in-extension data-use review. Direct Last.fm delivery is always tried first. Only if it is unavailable can completed track metadata and the Last.fm session key be sent through the relay. Cloud relay can be disabled at any time. When the service is contacted, Cloudflare may process the IP address and technical request metadata as the infrastructure provider.

Yandex Music may change its web interface. Control health and repair tools are included to make integration problems visible.
