Support

Need a hand with Synthze or Synthze Player? This page covers common support topics and explains the Android permissions used by Synthze Player.

Synthze synthesizer permissions

Synthze asks only for access needed by the synthesizer, MIDI, file, and purchase features you choose to use. Android shows a permission prompt when one is needed. You can review or change a granted permission at any time in your device's Settings app.

Bluetooth and MIDI devices

Synthze uses Bluetooth permissions to find and connect compatible Bluetooth MIDI controllers. On Android 12 and later, this appears as Nearby devices access. On some earlier Android versions, Android also requires location permission while scanning for nearby Bluetooth devices. Synthze does not use this permission for location features or to track your location.

Files, presets, and MIDI import

Synthze may use storage access on older Android versions for file-based workflows, such as importing MIDI files or preset backups and saving your own presets and recordings. Newer Android versions use the system file picker where available, so you choose the individual file to share with the app. The legacy write-storage permission is limited to Android 10 and earlier.

Internet and Google Play billing

Internet access is used for online services, including communicating with Google Play for available products and purchase processing. The Google Play Billing permission is used only to offer and manage in-app purchases; it is not a separate Android permission prompt.

What Synthze does not request

Synthze does not request access to your contacts, call history, microphone, camera, SMS messages, or calendar.

Synthze Player permissions

Synthze Player asks only for the access needed to play the media and features you choose to use. Android shows a permission prompt when one is needed. You can review or change a granted permission at any time in your device's Settings app.

Music and audio files

The app requests access to audio stored on your device so it can find, display, and play your local music library. On Android 13 and later this appears as Music and audio access; on older Android versions it is part of storage access. This permission lets the app read supported local audio files and their media information, such as titles, artists, albums, and embedded artwork. It does not let the app read unrelated documents or change or delete your files without a separate Android confirmation.

Videos

The app requests video access only when you use its local video-library features. This lets it find and play videos saved on your device. On Android 14 and later, Android may let you grant access to selected videos instead of the whole video library. You can still use music playback if you choose not to grant video access.

Notifications and background playback

On Android 13 and later, Synthze Player may request notification permission so it can show the active playback notification with controls such as play, pause, and next. The app also declares Android's media playback foreground-service and wake-lock permissions. These are not separate prompts: they allow music to continue when the app is not open and help prevent playback from stopping while a track is playing. They are used for media playback only.

Internet access

Internet access is used for online features, including live radio, streaming audio, remote artwork, lyrics where available, and the soundscape catalog. It is not required to play local music already on your device.

What Synthze Player does not request

Synthze Player does not request access to your contacts, call history, microphone, precise location, camera, SMS messages, or calendar.
