Delete the app

Attention. Deleting the app does not automatically cancel your subscription. If you have a current subscription, you should cancel it first.
  1. Tap the Yandex.Music icon on your device's screen and hold it until the Delete button appears in the upper-right corner of the screen.
  2. Drag the Yandex.Music icon to the Delete button.

Don't delete the app just to stop getting notifications. You can disable notifications in the settings of the web version at any time.
