Privacy Policy

Data Storage

All data in Shizuka — including session history, custom patterns, favorites, and settings — is stored exclusively on your device using Apple's SwiftData framework.

No data is sent to any external server, cloud service, or third party.

Data We Don't Collect

• No personal information (name, email, phone number)
• No health or wellness data
• No analytics or usage tracking
• No crash reports sent automatically
• No advertising identifiers
• No location data

Network Requests

Shizuka makes no network requests. The app works entirely offline. All breathing patterns, sounds, and animations are bundled with the app.

Data Deletion

Deleting the app removes all stored data permanently. There is no backup or recovery mechanism since no data exists outside your device.

Third-Party Services

Shizuka does not integrate with any third-party analytics, advertising, or tracking services.

Changes to This Policy

If we ever change this policy, we'll update this page. Given our commitment to local-only data storage, significant changes are unlikely.
