Privacy policy

1. In short

The microphone is only used to measure the sound level, during a measurement. No sound is recorded or sent: only level values (in dB) are computed. There is no account, and your sessions stay on your phone.

Third-party services communicate for what is strictly necessary: Google Play and RevenueCat for the Premium purchase and optional support, Google AdMob for the free version's banner (after your consent where it is required), and Firebase Crashlytics for anonymous crash reports, which you can turn off.

No usage analytics tool. No location.

2. The microphone and sound

The app asks for permission to use the microphone. It uses it in real time, only during a measurement and only while the app is open on screen, to compute a sound level (minimum, maximum, energy average, curve). The calculation is done inside the app, over short windows of about 150 milliseconds; the sound itself is neither recorded, nor kept, nor sent to us or to a third party, and no audio file is created.

The microphone is released as soon as the app leaves the screen. If you refuse the permission, measuring is not possible; you can grant it at any time in Android's settings.

To keep the screen from turning off during a measurement, the app keeps it on while it measures. A vibration can warn you when the alert threshold you set is exceeded.

3. What the app keeps on your phone

When you save a session, the app keeps in a local database: its title and note (if you write any), its date and duration, the minimum, average and maximum values, the points of the curve, the calibration status and your phone model (to judge how reliable the measurement is). Never any sound. Your settings (language, theme, palette, calibration, alert threshold) and a few local flags (for example to avoid asking for a review too often) are also kept on your device.

Android's automatic backup, when it is turned on on your phone, may include the sessions database (in your Google account, or when moving to a new device), but not your tokens or your purchase. We have no access to it.

This data is removed when you uninstall the app, or from “Settings > My data > Erase all my data” (sessions, calibration and preferences).

4. Export and sharing

You can share a result as an image, or export your sessions as a CSV file (a Premium feature). These actions only happen when you ask for them, through Android's share menu: the file goes where you decide, and we do not receive it.

5. The Premium purchase and optional support

Premium is a one-time, lifetime purchase handled by Google Play and RevenueCat. There is no account: RevenueCat uses a pseudonymous ID generated by its SDK and the status of your purchases, to recognise the purchase and restore it (“Restore my purchases”). The app also offers three optional support payments, paid once, which remove ads.

We never receive your payment method or banking identity.

6. Advertising in the free version

The free version may show a banner ad provided by Google AdMob, never during a measurement, and never with Premium or after a support payment. Where consent is required, it is collected through Google's form (UMP) before any ad.

To show and measure ads, Google AdMob may process, depending on your choices, an advertising ID (the app declares the matching permission), your IP address and information about your device and your interaction with the ad. dB Aura sends AdMob no sound, no measurement and no session. See Google's advertising policy.

You can reopen your choices at any time in the app's settings where this option is offered.

7. Crash reports

To fix errors, the app may send anonymous crash reports to Firebase Crashlytics (Google): the technical log of the error, device and Android version information, an installation ID. No sound, no measurement, no session is included. You can turn them off at any time with the “Crash reports” switch in “Settings > Privacy”.

8. Updates and reviews

The app may check for an update and offer to rate it using Google Play features. They are handled by Google Play. Google may also provide us with aggregated stability statistics (Android Vitals), not linked to you.

9. What we do not collect

We collect neither your name, nor your e-mail, nor your location, nor your contacts, and we never receive the sound picked up by the microphone, nor your sessions. The app uses no usage analytics tool.

10. Why this processing takes place

To provide the service you ask for (measuring, history, Premium purchase and support), for our legitimate interest in fixing crashes and maintaining the app, and, for advertising, on the basis of your consent where it is required. We do not sell your data.

11. How long we keep it

On your phone: sound is not kept; your sessions and settings are kept until you erase them or uninstall the app. With us: we keep no personal data about you. Purchase, advertising, crash reports and stability statistics: under the rules of Google Play, RevenueCat, Google AdMob and Firebase.

12. Your rights

Your sound does not leave your phone and your data stays there: you control it directly. You can withdraw the microphone permission, erase your data, turn off crash reports (section 7), withdraw your advertising consent (section 6) or uninstall the app.

For processing carried out by Google or RevenueCat, you can exercise your rights with them. For any question, write to us at [email protected]. You may also contact the data protection authority of your country.

13. Transfers outside the European Union

Google and RevenueCat may process data outside the European Union, in particular in the United States, with the safeguards provided by the GDPR (standard contractual clauses or an equivalent mechanism).

14. Children

The app is not directed to children under 13.

15. Changes

We will post any material change to this policy here, with its update date.
