Privacy Policy

Kaikoku (PocketChime) — Established July 10, 2026

Basic Policy

This app does not collect or transmit personal information that could identify users. There is no account registration, and the developer never holds identifiable personal information. We perform only anonymous usage analytics for service improvement and show non-personalized ads (no tracking) — see "Usage Analytics" and "Advertising and Tracking" below.

Information Handled Only On Your Device

Location — Used only to calculate sunrise and sunset and to retrieve the weather for your current location. Your location itself is never sent to the developer.
Calendar — Read only for "Prophecy for Thee" (displaying the day's next scheduled event). Its contents never leave your device.
Face ID — Used for authentication in the "Rite of Countenance." Facial data is handled entirely within Apple's own framework, and the app learns only whether it succeeded or failed.
Motion (acceleration, gravity) — Used only for the pendulum and wrist-rite effects.
Records such as settings, the Incantation Record, and Achievements — all are stored on your device (and in your iCloud backup).

External Services

Apple Weather (WeatherKit) — To retrieve weather, location coordinates are sent to Apple's service. Apple Weather data sources.
Firebase Crashlytics (Google) — To fix app issues, technical information at the time of a crash (device model, OS version, crash location, etc.) is sent. It does not include personal information such as name, contact details, or location.
Firebase Analytics / Google Analytics (Google) — Anonymous usage analytics to improve our service. It aggregates statistics such as which features are used, in a form that does not identify individuals. We do not use an advertising identifier (IDFA), and ad personalization is disabled.
App Store (StoreKit) — Payments are processed through Apple's payment infrastructure, and the developer never handles card information or the like.

Advertising and Tracking

This app displays ads through Google AdMob. All ads are non-personalized — we do not use an advertising identifier (IDFA), and we do not carry out cross-app or cross-device ad tracking (subject to App Tracking Transparency), so no tracking-permission dialog appears. To deliver ads, cap how often they appear, and prevent fraud, the ad provider (Google) may process device and approximate information, but it is never shared with the developer in a form that identifies you, nor used to track you across other apps. Ads come as a small banner at the bottom of some screens, occasional full-screen interstitials (daily-capped, never during sleep or an alarm), and a rewarded “Farsight” ad you may choose to watch to remove ads for a while. In the EU and UK, a Google User Messaging Platform consent form is shown before ads appear; while ads are removed (via the Pact or Farsight) none are shown.

Usage Analytics

To improve our service, we conduct anonymous usage analytics (Firebase Analytics / Google Analytics). This aggregates statistics such as which features are used most, in a form that does not identify individuals, and is not tracking for advertising purposes. Ad personalization is disabled. Our website likewise conducts anonymous analytics (Google Analytics), and in regions where consent is required, such as the EU, we request consent in advance.
