Privacy Policy
Last updated: August 14, 2026. This policy covers the 444 Hz Audio Tuning Converter website at 444hz.app and the 444 Hz Tuner apps for Android and iOS.
Your audio never leaves your device
Every step — reading the file, detecting the current A4 tuning reference, retuning the audio and verifying the result — runs locally on your device. Your files are never uploaded to us or to any third party, and we never receive, store or listen to them.
Retuned files exist only in your device's memory until you choose to save or share them. Closing the app discards them.
Information we collect
No account, no personal data. There is no sign-up, and we do not ask for your name, email address, phone number or location.
Anonymous usage events. We record basic, non-identifying events such as which screen was opened, whether a conversion succeeded, and a rough file-size bucket. These contain no filenames, no audio content and nothing that identifies you or your device.
Settings. Your tuning mode, tolerance and theme are stored locally on your device so the app remembers them. They are never sent anywhere.
Permissions used by the mobile apps
Files and media. Used only to let you pick an audio file to convert and to save the retuned file where you choose. The app cannot browse your library on its own.
Share sheet. Used only when you tap share, to hand the retuned file to the app you select.
Children's privacy
The app is safe for general audiences and does not knowingly collect any personal information from anyone, including children under 13.
Third parties and advertising
We do not sell data, we do not run advertising, and we do not share information with data brokers. Web fonts are loaded from Google Fonts, which may see your IP address as part of serving those files.
