DecibelRTA - Privacy Policy
Last updated: September 18, 2026
This Privacy Policy explains how DecibelRTA (« we », « our ») handles your data across iOS, iPadOS, and macOS.
1. Audio Data and Microphone Access
DecibelRTA provides real-time acoustic metrology and spectral analysis tools.
· Nature of the data: The app accesses your device's microphone solely to measure Sound Pressure Levels (SPL) and compute real-time frequency analysis (RTA).
· Local processing: Captured audio samples are processed exclusively in real time directly on your device by our native DSP engine.
· No recording or storage: No audio data is ever recorded, stored on disk, analyzed for speech, or transmitted over the internet. All processing is strictly volatile and local.
2. In-App Purchases and Financial Data
Optional Pro upgrades are processed directly by Apple via StoreKit. We do not collect, process, or store any payment information, credit card numbers, or billing addresses. All transactions are handled securely by Apple under the App Store Terms of Service.
3. Advertising and Third-Party Tracking
DecibelRTA does not contain any third-party advertising SDKs, tracking frameworks, or analytics services. We do not track you across apps or websites, and we do not collect advertising identifiers (such as IDFA).
4. Local Preferences
Your preferences (microphone calibration offsets, target curve selections, ballistic time constants, dynamic ranges) are stored locally on your device via standard local storage (UserDefaults). This configuration data is neither synchronized with external servers nor shared with third parties.
5. Permissions and User Rights
You retain complete control over system permissions. You can grant or revoke microphone access at any time through your device settings (Settings > Privacy & Security > Microphone on iOS, or System Settings > Privacy & Security > Microphone on macOS). Revoking microphone access will prevent the app from analyzing incoming sound.
