Short version

Jiyul is a single-player daily puzzle game. We do not collect any personal information. Nothing is uploaded, shared, transmitted, or sold. The app has no accounts, no ads, and no analytics or tracking SDKs.

What stays on your device

Today's score and your streak — saved locally with Apple's SwiftData framework.
The player name you set in Settings (default "지율").
Your language and sound preferences — saved in the iOS UserDefaults sandbox for this app.

If you delete Jiyul from your device, all of the above is removed.

Network

Jiyul does not connect to any server. The daily puzzle is generated deterministically on your device from today's date in the Asia/Seoul timezone — that is how everyone gets the same board without any network call.

System resources we use

Device clock — to decide which day's puzzle is "today" (in KST).
System audio — for the clear-rectangle sound effect, if you have sound turned on in Settings.

No location, contacts, photos, microphone, camera, or HealthKit access is requested.

What we do not do

No accounts. No sign-up. No login.
No advertising identifiers (IDFA). No ads of any kind.
No third-party analytics SDKs, tracking SDKs, or telemetry.
No cross-app tracking; no use of NSPrivacyTrackingDomains.
No AI service receives anything from your device.

Children

Jiyul is a calm number-puzzle game suitable for all ages, including children. The app does not collect personal data from anyone, regardless of age.
