Privacy policy

Last updated 7 October 2026

The Quiesco app does not collect, send or share any personal data on its own. There is no account, no server and no analytics. What the sensor measures stays on your phone and on your Quiesco unit.

What the app stores, and where

• Readings: carbon dioxide, temperature, humidity, light and noise levels downloaded from your unit. They are kept in a database on your phone.
• Your unit: its name, serial number and Bluetooth identifier, so the app can reconnect to it.
• A pairing key: a random key your unit issues when you enter its six-digit code. It is kept in the phone's secure storage (the iOS Keychain or the Android Keystore) and never leaves the device.
• Settings: your temperature unit, theme and sleep window.

None of this is sent anywhere. The noise sensor reports sound levels only; it does not record audio, and the app never uses your phone's microphone, camera, location or contacts.

Diagnostic reports

If something goes wrong, Settings → Send a diagnostic report shows a report you can email to us or share. It contains the app and phone versions, your unit's serial number, firmware and status, and the app's recent Bluetooth log. It never contains your readings or keys. The app shows you the whole report first, and it is only sent if you send it from your own mail app. We use it only to answer you, and delete it on request.

Bluetooth

The app uses Bluetooth only to find, pair with and read your Quiesco unit. On Android it asks for Bluetooth permission and declares that it does not use Bluetooth to work out your location.

Third parties

The app contains no advertising, tracking or analytics code and no crash reporting. Apple and Google may collect data about app downloads and crashes under their own privacy policies, according to your device settings.

Keeping or deleting your data

Your readings stay until you remove them. Forgetting a unit in the app's Settings tab deletes its readings and pairing key from your phone, and uninstalling the app deletes everything. A factory reset in the app also erases the log stored on the unit.

Children

The app collects no personal information from anyone, including children.

Changes

If this policy changes, the new version will be published on this page with a new date. The app's source code is public on GitHub, so you can check what it does.
