Privacy Policy

01Information We Collect

As a meditation tool, the App collects only the minimum information necessary to provide the service.

• Account information: email address, display name (including the identifier passed by Apple or Google when you sign in with them), and passkey details for account recovery (public key and identifier, if you register one)
• Meditation records: session duration, breath counts, PS score, mode, cumulative statistics, and meditation notes (if you write them)
• Device information: OS version, app version, device model (for error analysis and compatibility)
• Subscription status: subscription receipt and trial/active state provided by the App Store or Google Play
• Meditation location (optional): if you grant permission, the approximate place where a session started is rounded to about 1 km and saved with that session’s record. Meditation works exactly the same if you decline.

Photos and the camera are used only on your device to create a share image; the photos or videos you choose are never uploaded to our servers. The App does not request microphone or contacts access.

02How We Use Information

• 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 and free trials (the 7-day full trial and the 30-day sleep-meditation trial) (Legal basis: Performance of contract)
• Analyzing error logs and crash data to improve app stability (Legal basis: Legitimate interests)
• Notifying you of important service changes (policy updates, etc.) (Legal basis: Performance of contract)
• Usage statistics to improve the service: we use meditation records, sign-up dates and similar data to produce statistics such as weekly active users, usage by mode and retention by sign-up week. These statistics are stored and used only in aggregate form that cannot identify you, and are never used to identify individuals or for advertising. (Legal basis: Legitimate interests)

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 · Google Play — payment and subscription processing, 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. Copies in backups kept to protect against data loss remain for up to 100 days and are then deleted automatically.
• Legal retention: purchase receipts may be retained for up to 5 years as required by applicable law (e.g., e-commerce law).
• Preventing repeated free trials: so the same email address cannot claim free trials again, we keep an irreversible hash of the email address and the trial dates even after the account is deleted.
• Reasons for leaving (optional): the reasons and short comment you may leave when deleting your account are stored without any link to your account and are deleted automatically after 180 days.

05Your Rights (GDPR & Beyond)

Regardless of where you live, you have the following rights:

• Right to access: to obtain a copy of personal data we hold about you
• Right to rectification: to correct inaccurate information
• Right to erasure (right to be forgotten): exercisable immediately via [Profile → Delete Account] in the app
• Right to portability: to receive your data in a machine-readable format

06Children's Privacy

This service is not directed to children under 14 (a threshold that satisfies both the parental-consent requirement under Article 22-2 of the Korean Personal Information Protection Act and the under-13 protection standard of the U.S. COPPA). If we become aware that personal information from a child under 14 has been collected, we will take appropriate steps to delete such information.
