Decibel · Privacy Charter
// 01. OVERVIEW & ARCHITECTURE
Decibel is published by Outlayer Labs under a strict sovereign computing charter. All optical, audio, or geographic calculations occur in sandboxed hardware memory.
// 02. TELEMETRY & DATA EGRESS
We do not collect, store, sell, or share personal information through Decibel. No audio files or acoustic recordings are created.
- Zero account registration or identity credentials requested.
- Zero behavioral telemetry, crash analytics IDs, or device fingerprints.
- Zero network advertising SDKs or tracking pixels embedded in binaries.
- Zero transmission of user photos, audio frames, GPS points, or documents.
// 03. HARDWARE SENSOR PERMISSIONS AUDIT
Decibel requests strictly scoped hardware access necessary for physical execution:
Required exclusively to sample ambient air pressure and compute sound decibel (dB) levels. Incoming audio frames are analyzed in temporary memory to calculate mathematical RMS values and are immediately erased. No audio is ever recorded or saved to storage.
// 04. LOCAL SANDBOXED STORAGE
User settings (such as calibration offset and weighting preference) are saved locally on the device. No audio or measurement logs are uploaded to any external server.
Because application databases are stored in your device's private OS sandbox, deleting the application permanently erases all local data. Outlayer Labs maintains no cloud backups.
// 05. THIRD-PARTY SDK VERIFICATION
✓ Verified: Zero third-party ad networks, telemetry trackers, or marketing trackers are embedded.
The app does not use third-party analytics or tracking SDKs.
