Privacy policy

1. In short

The microphone is only used to measure the pitch of the note. No sound is recorded or sent: the audio stays in memory for the time of the calculation. There is no account, and your instruments and tunings stay on your phone.

Third-party services communicate for what is strictly necessary: Google Play and RevenueCat for the Pro purchase and optional support, Google AdMob for the free version's banner (after your consent where it is required), and a Clearforge Studio server for recommendations of other apps.

No usage analytics tool, no third-party crash reporting tool.

2. The microphone and sound

The app asks for permission to use the microphone when you open the tuner. It uses it in real time to compute the frequency of the note you play (note, octave, deviation in cents). The sound is neither recorded, nor kept, nor sent to us or to a third party, and no audio file is created.

The microphone stops as soon as the tuner is no longer visible (for example when you open a menu or Settings) or the app goes to the background. If you refuse the permission, the tuner cannot measure the note; you can grant it at any time in Android's settings.

The “reference note” is played through your phone's speaker with a local audio engine: nothing is downloaded. To keep the screen from turning off while you tune, the app keeps it on as long as the tuner is shown.

3. What the app keeps on your phone

Your instruments and tunings (including, with Pro, your profiles and custom tunings), your last instrument and tuning, the reference pitch, your settings (language, note names, theme) and a few local flags (for example to avoid asking for a review too often) are stored on your device only. Android's automatic backup is turned off for the app.

This data is removed when you uninstall the app, or from “Settings > My data > Erase all my data”. Erasing does not affect your Pro purchase.

4. The Pro purchase and optional support

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

We never receive your payment method or banking identity.

5. Advertising in the free version

The free version may show a banner ad provided by Google AdMob, never at the first launch and never with Pro. 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. Tuner sends AdMob no sound and no instrument data. See Google's advertising policy.

You can reopen your choices at any time in “Settings > Privacy options” where this option is offered.

6. Recommendations of other Clearforge apps

In the free version, the app may recommend another Clearforge Studio app, with a link to its Google Play page. Pro removes them.

To do so, the app downloads a catalogue from a Clearforge Studio server (clearforge-apps.clearforgestudio.com). The request sends the app identifier (com.clearforge.tuner) and, if there is one, the identifier of the last recommendation shown, so that recommendations rotate; your IP address is visible to the server, as with any Internet request. That server records no profile and keeps no database about you; it is hosted by Cloudflare.

7. 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.

8. 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. The app uses no usage analytics tool and no third-party crash reporting tool.

9. Why this processing takes place

To provide the service you ask for (measuring the note, Pro purchase and support), for our legitimate interest in suggesting our other apps, and, for advertising, on the basis of your consent where it is required. We do not sell your data.

10. How long we keep it

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

11. 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, withdraw your advertising consent (section 5) or uninstall the app.

For processing carried out by Google, RevenueCat or Cloudflare, 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.

12. Transfers outside the European Union

Google, RevenueCat and Cloudflare 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).

13. Children

The app is not directed to children under 13.

14. Changes

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