Synth (for M-VAVE) — Privacy Policy
Last updated: 2 October 2026
Synth (for M-VAVE) ("the app") is made by Ogbar ("I", "me"). This policy explains what happens to your data when you use the app from Google Play.
The short version
The app collects no personal data. It has no accounts, no ads, no analytics and no server of its own. Everything you make stays on your device.
What the app keeps
- Your sounds, presets, knob assignments and recordings are stored on your device, in the app's private storage. I do not run a server and I never receive them. Files you export (presets, WAV recordings) go only where you choose to save them.
- If you have Android backup turned on, Android may include the app's settings and presets in your personal Google backup. That backup belongs to your Google account; I cannot see it.
Bluetooth and location
The app uses Bluetooth only to find and connect your MIDI keyboard (for example the M-VAVE SMK-25). It reads the notes and knob movements the keyboard sends and nothing else.
On Android 11 and older, Android requires the location permission for any Bluetooth scan. The app asks for it only for that reason; it never reads or stores your location. On Android 12 and newer the app scans without location access.
Purchases (Google Play)
The Pro upgrade is sold through Google Play. Google Play handles the payment; I never see your payment details. The app only receives a confirmation from Google Play that your Google account owns Pro, so it can unlock it, also after a reinstall.
Children
The app is not directed at children under 13, and I do not knowingly collect data from them.
Deleting your data
Delete presets and recordings inside the app, or uninstall the app to remove everything it stored.
Changes
If this policy changes, the new version will be published at this address with a new date.
