This Privacy Policy explains how Zen24 (“the app”, “we”, “us”) handles information when you use the app. Zen24 is a calm, offline 24-point math puzzle game. We do not collect, sell, or share your personal data.
Zen24 has no accounts, no sign-up, and no servers of our own. We do not collect any personal information about you, and we have no analytics, advertising, or third-party tracking SDKs in the app.
Your game progress — such as solved-puzzle history, statistics, achievement progress, hint count, and settings (sound/haptics) — is stored locally on your device. This information stays on your device and is not transmitted to us.
If you are signed in to iCloud, your game progress may be synchronized across your own Apple devices using Apple’s iCloud key-value storage. This data is handled entirely by Apple under your Apple Account and is not accessible to us. See Apple’s Privacy Policy for details.
Game Center is optional. If you choose to sign in, Apple’s Game Center service manages leaderboards and achievements associated with your Apple Account. That information is provided and controlled by Apple, not by us, and is governed by Apple’s Privacy Policy.
Zen24 offers a one-time in-app purchase (“Zen Pro”). All payments are processed by Apple through the App Store. We never receive or store your payment details, card numbers, or billing information. Apple provides us only with anonymous, aggregated sales reports.
Zen24 is suitable for all ages and is rated 4+. We do not knowingly collect any personal information from anyone, including children.
We do not integrate third-party advertising or analytics services. The only external services involved are Apple’s own platform features (iCloud, Game Center, and App Store purchasing), which operate under Apple’s policies.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date.
