Privacy Policy

Pitch Checker · Developer: GF43 · Effective October 11, 2026

This policy explains how Pitch Checker handles information when measuring your vocal pitch. The app does not require an account.

Microphone access and audio data

The app accesses the microphone only when you start listening. Audio is analyzed on your device to find the note, frequency and cents deviation. On Android, capture may create a temporary audio file in the app's private cache; that file is not uploaded.

GF43 does not receive, transmit to a server, sell, or share your audio or pitch results.

Data stored on your device

The app stores only your language choice and whether the introduction has been shown. You can remove this data by clearing the app's data or uninstalling the app.

Advertising and third-party services

The app uses Google AdMob to show ads. The Google Mobile Ads SDK may automatically process IP address, advertising or device/app identifiers, device information, ad interactions, and diagnostics to deliver, measure, protect, and improve advertising. Google processes and retains this information under its own policies.

See the Google Privacy Policy and how Google uses information from partner apps.

Consent and advertising choices

Where required by law, the app uses Google's User Messaging Platform (UMP) to request and store your choices before initializing advertising. You can change your choices in the app's Settings > Ad privacy, or manage your advertising identifier in your device settings.

Device permissions

Microphone permission is required to measure pitch. The app may also use audio-settings permission to configure a recording session. You can revoke microphone permission in your device settings; pitch measurement will then be unavailable.

Children

The app is not directed to children under 13, and GF43 does not knowingly collect personal information directly from children.

Security and retention

The data described above remains in the app's storage area on your device until you clear the data or uninstall the app. No storage or transmission method is completely secure. Information processed by Google is retained under Google's policies.

Policy changes

We may update this policy when app functionality or legal requirements change. The new version and effective date will be posted at this URL.
