Privacy policy

Last updated: 2 June 2026

Hush is made by 23 works. We built it to be private by design. This explains, in plain language, what the app does and does not do with your information.

The short version

Hush requires no account, collects no personal data, contains no advertising, and uses no third-party analytics or tracking. What happens on your phone stays on your phone.

Information we collect

None. We do not collect, store, transmit, or sell any personal information. The app has no login, no profile, and no servers that receive your data.

Data stored on your device

Hush saves a small amount of information locally — such as whether you've completed the intro, your most recently played sounds, your saved mixes and a gentle weekly listening total. This never leaves your device and is removed if you delete the app.

Listen together (local network)

The optional Sync feature lets two nearby devices play the same sounds at once, over Apple's encrypted local peer-to-peer networking. The only information exchanged is which sounds are playing and the selected timer, sent directly between the devices for that session. Nothing is sent to us or any third party, and nothing is stored.

Background audio

Hush can keep playing while your screen is locked. This uses standard iOS audio playback and involves no data collection.

Permissions

Hush asks for local network access only to enable the optional Sync feature. It does not request your microphone, camera, contacts, location, photos, or any other personal data.

Children

Hush is suitable for all ages and does not knowingly collect any information from anyone, including children.

Changes

If we ever change this policy, we'll update the date at the top of this page.
