How can I customize ringtones and notification sounds?

To use custom ringtones and notification sounds on Android, please perform the following steps:

  1. Copy your ringtone sound files to the folder “ringtones” and notification sound files to the folder “notifications”. Alternatively, you can use third-party apps like Ringtone Maker, which will take care of copying the files to the correct location for you.
  2. In the Threema app, navigate to Settings > Notifications, where you can now select the sound files you have just added.
