Privacy Policy

Effective September 28, 2026

Stillwater: Calm Pipe Puzzle ("the app") is developed by Vladyslav Shchuka ("we", "us"). Short version: the app collects nothing.

What we collect

Nothing. We don't run servers, the app has no accounts, no analytics, no ads and no tracking, and it doesn't connect to the internet on its own.

Data stored on your device

Your progress, boards in progress, statistics, Daily Flow streak and settings are stored only on your iPhone. The streak and today's Daily Flow status are kept in storage shared with the app's widget so it can show them. Deleting the app deletes this data.

Purchases

The Full Game is sold by Apple through the App Store. We never see your payment details. The app only asks Apple whether your Apple Account owns the Full Game. Apple's handling of that information is covered by Apple's Privacy Policy.

Children

The app is rated 4+ and collects no personal information from anyone, including children.

Changes

If this policy changes, we'll update this page and the effective date above.
