Privacy Policy

ZenBlocks · last updated 22 September 2026 · Data controller: Oshi Lab, Switzerland

The short version

ZenBlocks has no account, no sign-in and no server of mine. I receive no personal data from this app at all. Your board, your score and your tokens are written to storage on your own device and stay there.

What is stored, and where

All of it lives in the app's own storage on your device. It is included in an encrypted iPhone or iPad backup if you make one, and deleting the app deletes every bit of it.

Purchases

Premium, and any token pack, is sold and processed entirely by Apple through the App Store. I never see your name, your payment method or your Apple Account. The app asks Apple's StoreKit whether a purchase exists on this device and receives yes or no.

Advertising and tracking

There is none. ZenBlocks shows no ads, contains no advertising SDK, never asks for permission to track you and never reads the advertising identifier.

Game Center

If you sign in to Game Center, the leaderboard is operated by Apple under Apple's privacy policy. It is optional, the game is complete without it, and nothing from it reaches me.

Analytics

There are none. No crash reporter, no attribution SDK, no telemetry, no product-analytics library. I do not know how many boards you have cleared. There is no third-party code in the app.

Children

ZenBlocks is not directed at children under 13, and collects no personal data from anyone of any age.

Your rights

The GDPR gives you rights of access, rectification, erasure, restriction, portability and objection over personal data a controller holds about you. I hold none from this app, so there is nothing to disclose or erase on my side; deleting the app erases everything on yours. If you would like that confirmed in writing, write to contact@oshi-messenger.com.

Changes

If this policy changes, the date above changes with it, and the new text is published here before the change ships in an update.
