Data stored in the app
Shuukan stores the habits, tags, notes, completion history, reminder settings, and app preferences you create. This information is used only to provide the habit tracking features shown in the app.
Effective 2 June 2026
Privacy Policy
Shuukan is built to keep habit tracking personal. The app is free, has no ads, and does not use third-party analytics.
Local storage and iCloud
By default, your data is stored on your device. If you turn on iCloud Sync, your data may sync through Apple iCloud between devices signed in to the same Apple ID. The developer does not receive or operate a server for your habit data.
Notifications
If you enable reminders, Shuukan schedules notifications using your chosen reminder time and habit name. You can manage notification permission in iOS Settings.
Export and support
Data export creates a JSON file only when you choose to export it. If you email support, your email address and message are handled by your email provider and are used only to respond to your request.
Analytics, ads, and purchases
Shuukan does not include third-party advertising, third-party analytics, subscriptions, or in-app purchases.
Retention and deletion
Your local app data remains on your device until you delete it in the app or remove the app. iCloud-synced data can be managed through iCloud and device settings. For privacy questions, contact support.
