Privacy Policy for VibeSync
This application (VibeSync) is provided by "Wu Ye" (Independent Developer). We are committed to protecting your privacy.
1. Data Collection and Use
We do not collect, store, or transmit any personally identifiable information (PII) or raw audio data.
Microphone access is used only to measure ambient sound levels (decibels) in real-time. No raw audio is recorded, saved, or uploaded to any server. All sound level processing happens locally on your device.
Vibration and Bluetooth permissions are used solely for the core functionality of the app.
2. Data Retention and Deletion Policy
Retention Period:
Microphone sound level data is processed locally in real-time and is deleted immediately (retention time: 0 seconds).
Anonymous usage and crash data collected via Firebase Analytics and Crashlytics is retained for a maximum of 2 months, after which it is automatically deleted.
Server-side Verification:
This app uses Google Play’s server-side purchase verification to confirm the validity of subscriptions and one-time purchases. Only the necessary purchase token is sent to our server. No personally identifiable information is included or stored during this process.
How to Delete Your Data:
We do not require account creation and do not store any personal account data on our servers. Therefore, there is no user account to delete.
You can completely remove all local app data at any time by:
Uninstalling the app from your device, or
Going to your device Settings → Apps → VibeSync → Storage → Clear Data.
If you have any questions regarding Firebase data, you may contact us via the developer email listed on the Google Play Store.
3. Third-Party Services
This app uses Google Firebase Analytics and Firebase Crashlytics for anonymous usage analysis and app stability monitoring. All data collected is anonymized and not linked to any individual user.
