Privacy Policy

Kizuna is a private two-person prompt app for people who want deeper connections. One prompt. Two answers. No winner. This policy explains the data needed to run private sync, pairing, notifications, safety controls, and account deletion.

Information the app uses

• Account and identity metadata, including Sign in with Apple identifiers and the display name used for pairing.
• Device metadata needed for private sync, device key registration, and notification routing.
• Pairing and relationship-space metadata, including invites, pair membership, room notification settings, and leave-pair state.
• Prompt round metadata, including prompt identifiers, timing, state, save choices, delete requests, and sync status.
• Encrypted response envelopes for text, audio, and video answers.

Private answers

Private answers are encrypted on the device before private sync. The relay is designed not to store plaintext text answers, plaintext audio, plaintext video, transcripts, sentiment analysis, or relationship scores.

Notifications

Push notifications, when enabled, use generic private-update text. Notification payloads should not include prompt text, answer text, media previews, relationship labels, or ciphertext.

Ads and subscriptions

The planned business model is feature-equal freemium: free and paid users receive the same relationship features, and the paid tier removes ads. Ads and subscriptions are not enabled until App Store Connect setup, privacy review, and sandbox testing are complete. Ads must not use private answers, prompts, relationship type, recordings, transcripts, or emotional inferences for targeting.

Screen capture

iOS screenshots cannot be fully blocked by normal third-party apps. The app hides private content during active screen recording or mirroring where iOS allows it and warns after screenshots.

Data deletion

The app includes account deletion and leave-pair flows. Deleting local data also removes keys needed to decrypt private answers on that iPhone. Unsaved rounds can be deleted automatically unless both people choose to save them.

Children

This build is intended for users who are 13 or older. Use with children under 13 needs a separate consent-ready version.

Health and emergency limits

Kizuna is not therapy, medical care, or emergency support. If someone may be in immediate danger, call local emergency services or a crisis line.

Third-party services

The app uses Apple platform services such as Sign in with Apple and Apple Push Notification service. Any future ad, analytics, attribution, crash reporting, or AI service must be reviewed before it is enabled and reflected in this policy.
