Privacy policy

1. In short

ToneDry never uses the microphone and has no account: the sound of the cycles is generated on your phone, and your settings stay there.

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 ads (after your consent where it is required), Firebase Crashlytics for anonymous crash reports that you can turn off, and a Clearforge Studio server for recommendations of other apps.

No usage analytics tool. No location.

2. Sound, volume and sensors

The cycles, the sound test, the stereo test and the manual mode play a sound created by the app itself on the speaker: nothing is downloaded. The app does not ask for permission to use the microphone and records no sound.

During a cycle, it raises the media volume to the maximum and then restores it, detects whether headphones or a Bluetooth device are connected to warn you, keeps the screen on, and can vibrate the phone (a Pro option). For the guided protocol, it reads the accelerometer to know how the phone is held; these readings are used on the spot, and are neither kept nor sent.

The widget, the quick settings tile and the icon shortcut only start a cycle in one tap: they collect nothing.

3. What the app keeps on your phone

Your settings (language, theme, palette, duration, Pro frequency and calibration, vibration, audio output) and a few local flags (number of launches and cycles, date of the last cycle, whether the introduction and tutorial were shown, to avoid asking for a review or showing an offer too often) are stored on your device. There is no database and no account. Android's automatic backup, when it is turned on on your phone, may keep these settings in your Google account; we have no access to it.

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

4. Sharing

After a “Clearer” comparison, you can share a result card as an image. This only happens when you ask for it, through Android's share menu: the image goes where you decide, and we do not receive it.

5. 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 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 and, from time to time after a completed cycle, a full-screen ad, provided by Google AdMob. Pro and the support payments remove ads. 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. ToneDry sends AdMob no settings and no usage data. See Google's advertising policy.

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

7. Recommendations of other Clearforge apps

In the free version, the app may occasionally recommend another Clearforge Studio app, with a link to its Google Play page (never with Pro or after a support payment, and not during a cycle). You can choose “Don't show again”.

To do so, the app downloads a catalogue and the icon of the suggested app from a Clearforge Studio server (clearforge-apps.clearforgestudio.com), then keeps them in memory on your phone. The request sends the app identifier (com.clearforge.tone_dry) 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.

8. 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. You can turn them off at any time with the “Anonymous error reports” switch in Settings.

9. 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.

10. What we do not collect

We collect neither your name, nor your e-mail, nor your location, nor your contacts, and the app never uses your microphone. It uses no usage analytics tool.

11. Why this processing takes place

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

12. How long we keep it

On your phone: your 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.

13. Your rights

Your settings stay on your phone: you control them directly. You can erase your data, turn off crash reports (section 8), choose “Don't show again” for recommendations, withdraw your advertising consent (section 6) 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.

14. 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).

15. Children

The app is not directed to children under 13.

16. Changes

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