Kizuna Calendar (the "App", "we", "our", or "us") is an iOS and iPadOS application that helps users understand Japanese holidays, long weekends, and etiquette moments. This Privacy Policy explains what information the App handles, how it is used, and the choices you have.

We designed Kizuna to be quiet and local by default: the App does not require an account, and no personal identifiers are needed to use it.

1. Information We Collect

1.1 Information you provide

The App does not require a user account. You are never asked for your name, email address, phone number, address, or any other personal identifier to use the App.

You may voluntarily contact us by email. Any information you include in that email (for example, your email address and message content) is received solely by us and used only to respond to your request.

1.2 Information the App stores on your device

To provide the features described in the App, the following information is stored locally on your device:

• Cached Japanese holiday dataset for offline use.
• Your language preference.
• Your notification preferences.
• Reminders you create (target date, scenario type, title, enabled state, created timestamp).
• Premium entitlement state (whether the one-time in-app purchase has been unlocked).
• A flag indicating whether first-launch onboarding has been completed.

This information is stored using standard iOS on-device storage mechanisms. It is not transmitted to us.

1.3 Anonymous product analytics

The App may collect anonymous, aggregated product analytics events to help us improve the experience. These events describe how features are used, not who you are. Examples of events include:

• app_open, onboarding_complete, language_selected
• notification_permission_granted
