Microphone and audio
Microphone permission is used for the foreground meter, manual recording and user-started overnight monitoring. AAC m4a recordings remain in app-private storage. Level calculations, detection, trimming, playback and PDF creation take place on the device. Audio, timestamps and notes are not sent to the developer or Google servers. Sound categories are manually selected, not inferred.
Start and stop
Recording and monitoring show a persistent notification. Monitoring stops on user request, the configured time, 14 hours, low storage, low unplugged battery or changed audio routing. The ordinary meter stops when the app leaves the foreground. The microphone does not automatically start after reboot. Periods where Android prevents audio capture are not filled with invented measurements.
Local records
The app stores recordings, timestamps, durations, captured digital levels, calibration/input-route details, selected categories, notes, an optional “woke up/could not sleep” contextual check, report recipient/place/author and settings locally. It does not access location, contacts, phone status or health records. Report addresses are manually entered text. The optional check is a contextual noise note, not sleep tracking.
Deletion and backup
Deleting a record deletes its associated private recording. Settings → Data can clear normal data. Android app-data clearing or uninstall removes local records and settings. Cloud synchronization, app cloud backups and device-transfer backups are disabled. Files already exported must be deleted at their destination. App locking verifies the device lock; it does not independently encrypt audio.
Billing diagnostics and identifiers
Google Play Billing 9.1.0 processes purchase/restore data and sends technical diagnostics, app/OS/library versions and client/session identifiers to Google over HTTPS. No advertising ID is used. There is no developer analytics SDK, ad SDK or server. Record contents and audio are not passed to Billing. Google-managed retention and deletion follow Google policies.
Purchases and sample
Plus is a Google Play one-time product. Google handles payment details; the developer does not receive card numbers. The app checks purchased, pending, acknowledged and restored states and keeps only verified entitlement. Fictional sample data and synthetic audio are separate from normal storage and do not alter normal settings or purchase rights.
Sharing
Only an explicit share action sends the selected AAC, PDF, CSV or ZIP to the chosen Android share destination with temporary file-read permission. Audio may contain surrounding conversations. Check what you share and the destination’s privacy practices.
