The App does not request access to microphone, camera, location, contacts, or photos.

• To save meditation sessions and display statistics (Legal basis: Performance of contract)
• Cross-device synchronization (viewing records on other devices signed in with the same account) (Legal basis: Performance of contract)
• Verifying and managing Premium subscription status (including the 30-day sleep-meditation trial policy) (Legal basis: Performance of contract)

The App does not use an ad-supported model and does not use your data for advertising targeting.

03Third-Party Sharing & Processors

We do not sell your personal information or share it for third-party marketing. We rely on the following processors to operate the service:

• Google Firebase (Authentication, Firestore, Cloud Storage, App Check, Crashlytics, Analytics) — authentication, data storage, sync, crash reporting, usage analytics
• Apple App Store — payment processing, subscription, app distribution
• RevenueCat — Subscription state management and receipt validation. Data processed: subscription receipts, user identifiers, and subscription history.

Each processor protects data under its own privacy policy. We share only what is necessary to operate the service.

International data transfers: Google Firebase processes data transfers outside the European Economic Area (EEA) under Standard Contractual Clauses (SCCs). RevenueCat and Apple apply equivalent safeguards for international transfers.

For users in Japan: Your data may be transferred outside Japan via Firebase and other processors. Each processor maintains appropriate safeguards in accordance with applicable law.

04Data Retention

• While your account is active: meditation records and account information are retained.
• Upon account deletion: all personal information and meditation records are permanently deleted within 30 days (including backup rotation cycles).
• Legal retention: purchase receipts may be retained for up to 5 years as required by applicable law (e.g., e-commerce law).
