Privacy Policy - Noise Meter Log

The short version. The app has no account, no server of ours, no analytics, no advertising and no tracking. Your sessions, event markers and notes live in the app's storage on your phone. We cannot see them.

The microphone. Measuring the sound level needs the microphone. Android asks for it when you tap Allow microphone on the Meter tab. The sound is turned into a loudness number in memory, a few times a second. No audio is recorded, saved or sent anywhere, and the app has no way to play back what it heard. If you refuse the permission, the rest of the app still opens, but nothing can be measured.

Notifications and the screen off. To keep a logging session running when the screen is off, the app runs a foreground service of the microphone type and shows a notification with the running time, the current level and a Stop button. It also keeps the processor awake while a session logs. A Pro alert is one notification, and optionally a short vibration, when the level has stayed above the limit you set. Notifications are optional; without them the session still runs.

What is saved. For each session the app saves its title, start time, the level for every second (average and loudest), the event markers (when, how long, peak), the limit and calibration offset in use, and a note if you write one. Settings such as the limit and the calibration offset are saved too. This stays on your phone.

Files you choose. A report, a CSV or a short summary goes to a temporary file in the app's cache and is handed to the app you pick in the Android share sheet. A backup or the all-data CSV is written only to a place you pick in the system file dialog, and a backup is read only when you pick one. The app asks for no storage, photos, contacts, location or Bluetooth permission.

What Google collects. Pro is bought through Google Play Billing, and the optional review prompt uses Google Play's in-app review. Google handles those under its own privacy policy. The Play data safety form lists App info and performance > Diagnostics as collected by Google Play Billing, not shared by us, required for purchases to work. The app itself sends nothing over the network and does not request the internet permission.

Your controls. Settings > Export all my data saves a CSV of every session, event and level. Settings > Back up saves your sessions to one file you choose, and Restore reads it back. Settings > Delete all data erases every session and setting and returns the app to a fresh install; your Pro purchase stays with your Google account and can be restored. Deleting one session removes its levels and events. Uninstalling removes the data as well. If Android backup is on for your phone, the app database and settings can be part of your Google backup. Turning backup off in Android settings stops that.

Accuracy. A phone microphone is not a certified sound level meter. Readings are an estimate. Do not rely on them where a legal limit, a safety rule or a dispute depends on the number.

Recording people. The app does not record sound, only its level. Where you place a phone to measure a neighbour or a workplace, follow the local rules on measuring and on sharing the result.

Children. The app is not designed for children under 13 and collects nothing from anyone.

Changes. If this policy changes, the new version is published at the address above with a new date. Last updated: 2026-11-06.
