Privacy Policy
Effective date: August 23, 2026
Sufy Studios ("we," "us," or "our") built DroneSynth as a self-contained music synthesizer app. This policy explains what happens with your information when you use it.
We do not collect any personal data
DroneSynth does not have a server, does not use analytics, does not use advertising SDKs, and does not track you or your device across apps or websites. No data ever leaves your device.
What's stored, and where
DroneSynth saves your synth presets and app preferences locally on your device using Apple's standard UserDefaults storage. This information is never transmitted anywhere, never shared with us or any third party, and is deleted automatically if you delete the app.
In-App Purchases
DroneSynth offers an optional one-time purchase ("Stereo Filters") processed entirely through Apple's App Store (StoreKit). Your payment information is handled by Apple according to Apple's own privacy policy — we never see or receive your payment details. We only receive confirmation of whether the purchase was completed, which is used solely to unlock the feature on your device.
Children's Privacy
DroneSynth does not knowingly collect any information from anyone, including children, because it does not collect information at all.
Third-Party Services
DroneSynth uses open-source audio libraries (AudioKit and related packages) that run entirely on-device to generate and process sound. None of them transmit data off your device.
Changes to This Policy
If this policy changes, we'll update the effective date above and post the revised version at this same URL.
