Signal Zoo collects nothing. Your creatures stay on your device.

AppSignal Zoo: Math Creatures (iPhone and iPad) Updated10 November 2026 Contact[email protected]

Signal Zoo is an iPhone and iPad app by Dylan Cantor ("I", "me") for growing creatures out of math and hearing them. This policy explains what the app does with your data.

The short version

  • Signal Zoo does not collect, store, sell or share any personal information.
  • The app works entirely offline and does not send data anywhere.
  • There are no accounts, ads, analytics or third-party tracking SDKs.

What stays on your device

The app saves the creature you're working on and the creatures you've placed on your Stage, so they're there next time you open it. These stay in the app's storage on your iPhone or iPad and are deleted when you delete the app.

Exporting audio. When you tap Export audio, the app renders your Stage to an audio file on your device and opens the iOS share sheet. Where the file goes from there is up to you; Signal Zoo uploads nothing.

TV mode. TV mode only changes how the Stage is shown on your screen. If you mirror your screen to a TV with AirPlay, that connection is handled by iOS, not by the app.

Signal Zoo does not access your location, microphone, camera, contacts, photos, health data or any identifier for advertising.

Children

Signal Zoo is suitable for all ages and does not collect personal information from anyone, including children under 13.

Changes

If this policy changes, the new version will be posted here with a new date. If a future version of Signal Zoo starts collecting any data, the policy will say so before that version is released.
