Privacy Policy

Last updated: 31 August 2026

The short version

Audio never leaves your phone. The recording is analysed on the device, and no sound is uploaded anywhere — not to us, not to anyone.

What the app handles, and where it stays

Microphone recordingsCaptured and analysed entirely on the device, stored locally, and deletable at any time. Never uploaded.
Vibration dataRead from the phone's own accelerometer during a test; stays on the device with the recording.
Diagnosis historyKept locally so you can compare tests over time.
AccountThere is none.

Crash and error reporting

To find and fix defects, the app sends crash and error reports to Sentry, our error-monitoring provider. A report contains the error itself, a technical breadcrumb trail, the app version, the device model and the operating system version. Personal data is stripped before sending by an automatic redaction filter, and reports are never sent from development builds. No audio, and no fragment of audio, is ever part of a crash report.

You can switch this off. Settings → Send crash reports stops the app sending anything at all; everything else keeps working. Reports are processed on Sentry's servers in the United States and are deleted automatically after 90 days.

Purchases

Payments are processed entirely by Google Play or the Apple App Store. Whether a purchase or subscription is active is checked through RevenueCat, our subscription-management provider, which receives the store transaction and an anonymous app identifier — never your name, e-mail or card. We never see or store your card details, address or payment identity — the app only learns whether a purchase is active.

Advertising and tracking

The app contains no advertising, no analytics SDK, no advertising identifier and no cross-app or cross-site tracking of any kind. Nothing you do in the app is sold or shared for marketing.

Children

The app is a household utility and is not directed at children under 13.

Your data, your control

Deleting a session in the app, or uninstalling it, removes the recording and its analysis permanently. Because we operate no accounts and no servers holding your content, there is nothing for us to delete on our side and nothing to export from us. If you have any question about your data, write to [email protected] and you will get an answer from a person.

If you are in the EU, the UK or California

The controller of the little data described above is Dmitrii Zusmanovich, an individual developer, reachable at [email protected]. Crash reports are processed on the basis of legitimate interest — keeping the app from crashing — and you can withdraw from that at any time with the switch in Settings, with no effect on anything else. Because there is no account and no server of ours, we hold nothing about you to access, correct, port or erase; what exists is on your own device and under your control. You retain the right to lodge a complaint with your national data-protection authority. We do not sell or share personal information, and we have no “sale” or “targeted advertising” to opt out of.

Changes

If this policy changes, the date at the top changes with it, and the updated text is published on this page before the release that relies on it.
