Privacy Policy

Hush · Last updated 31 July 2026

Hush collects no data. It is a fully offline sound app: every sound is synthesized on your device, and your use of it is entirely private.

What we collect

Nothing. Hush does not collect, transmit, or share any personal information or usage data of any kind.

What stays on your device

Hush saves your custom sound shapes, favorites, volume, and window layout so the app remembers them between launches. This information is stored only on your device (and in your device backups, which you control). It is never sent anywhere — the app makes no network connections at all.

How it works

• Fully offline. All audio is generated on your device. The app contains no networking code.
• No analytics or tracking. No analytics, no advertising, and no third-party SDKs or trackers.
• No account. There is no sign-in or profile.

Children

Because the app collects no data whatsoever, it is suitable for users of all ages.

Changes

If this policy ever changes, the updated version will be posted at this address with a new "last updated" date.
