# Privacy Policy for Shikaku Zen
_Last updated: 13 July 2026_
Shikaku Zen (“the app,” “we,” “us”) is a puzzle game developed for iOS. This policy explains what information the app handles and how.
## Summary
Shikaku Zen does not require an account and does not collect any personal information for gameplay. The only data that leaves your device is the minimum needed to process an optional Pro purchase through our payment provider, RevenueCat.
## What stays on your device
Your puzzle progress, best times, daily streak, and app settings are stored locally on your device only (and in your personal iCloud device backup, if enabled). We have no access to this information.
## Purchases (RevenueCat)
If you choose to buy the optional Pro upgrade, purchase validation is handled by our subscription platform, [RevenueCat](https://www.revenuecat.com). RevenueCat may process:
– An anonymous app-generated user identifier
– Purchase and subscription/entitlement status
– Device and app metadata needed to validate a purchase with Apple (e.g., device type, OS version, app version)
This data is used solely to verify your purchase and unlock the Pro features on your device. We do not receive or store your payment details (card number, Apple ID, etc.) — payment is handled entirely by Apple. For details on RevenueCat’s own data practices, see their [privacy policy](https://www.revenuecat.com/privacy).
## What we don’t do
– No user accounts or sign-in
– No analytics or advertising SDKs
– No tracking across apps or websites
– No sale or sharing of data for advertising
## Permissions
The app requests no device permissions: no camera, location, contacts, or notifications.
## Children’s privacy
Shikaku Zen does not knowingly collect personal information from children. Gameplay data never leaves the device, and purchase processing (only triggered by an optional, explicit purchase action) is handled the same way for all users.
## Your rights
Since no personal data is collected outside of the minimal purchase-validation data described above, there is no account data to access, export, or delete. If you have questions about data RevenueCat processes on our behalf, you may contact us and we will assist.
## Changes to this policy
If this policy changes, the update will be posted here and reflected in the in-app privacy policy screen.
