Privacy Policy

Effective October 1, 2026

ZipWorm is a puzzle game made by an independent developer. It has no accounts, no ads, no analytics and no tracking. This policy explains the little data the app handles.

Data stored on your device

Your game progress (unlocked gardens, streak, best times, the puzzle in progress, and your sound settings) is saved only on your device. It isn't sent to us or anyone else, and deleting the app deletes it.

In-app purchases

ZipWorm Plus is sold through Apple's App Store. Payment is handled entirely by Apple; we never see your name, email or payment details.

To check whether you own Plus and to restore it, the app uses RevenueCat, a purchase-management service. When the app opens or you make or restore a purchase, RevenueCat receives a random anonymous ID created by the app, your purchase history for ZipWorm (the App Store receipt), and basic technical information such as your device model, OS version, app version, country/region and IP address. This is used only to provide and restore your purchase. It isn't used to identify you, for advertising, or to track you across apps or websites. See RevenueCat's privacy policy.

Children

ZipWorm is suitable for all ages and doesn't knowingly collect personal information from anyone, including children.

Your choices

You can delete all local data by deleting the app. To ask about or request deletion of purchase records held by RevenueCat, email us with the approximate date of your purchase.

Changes

If this policy changes, the updated version will be posted on this page with a new effective date.
