We believe your audio files, recordings, and lyrics belong exclusively to you. Stone is built around a zero-telemetry architecture.
Stone is a login-free mobile DAW. We do not require or collect user accounts, email addresses, names, or contact details. There are no tracking scripts, cookies, analytics packages, or marketing pixels installed in the application or on this website.
All audio files recorded within Stone remain in your device's sandboxed document directory (getApplicationDocumentsDirectory()/StoneProjects).
No audio is uploaded to remote servers, cloud databases, or third-party storage utilities unless you explicitly invoke your operating system's native share sheet (e.g. sharing an exported MP3 via email, text, or a cloud drive of your choice).
Stone enforces directory traversal security guards. File read and write permissions are restricted to the local workspace root folder. The app cannot access or alter media libraries, files, or settings outside its sandbox boundary.
To capture audio tracks, Stone requires microphone access (RECORD_AUDIO on Android and NSMicrophoneUsageDescription on iOS). This permission is queried at runtime and is used only to route hardware microphone feeds into the local encoder.
Because Stone runs entirely offline with zero server sync components, your recording sessions, raw inputs, lyric notebook drafts, and exported balances are structurally impossible for us to monitor, analyze, or monetize.
