Privacy Policy

Last updated: October 2, 2026

Kizunami ("we", "us") is an app for chatting with AI companions and for remembering loved ones through their own words. This policy explains what we collect, why, and the choices you have.

What we collect

• Account information. If you sign in with Apple or Google we receive an account identifier and, if you allow it, your name and email (Apple may give us a private relay address). You can also use the app without signing in; we then create an anonymous account identifier.
• The name you choose for companions to call you.
• Your conversations. Messages you send and replies you receive, plus reactions, are stored so your chats are available across sessions and devices.
• Voice messages. When you send a voice message, the audio is sent to our AI provider to transcribe it and generate a reply. Audio files are kept on your device; the transcript is stored with your chat.
• Loved-one details you provide. When you create a loved one, the screenshots, photo, notes and memories you add are sent to our AI provider to build their speaking style. The resulting profile is stored in your account and is private to you. We do not keep the screenshots after processing.
• Usage and plan information, such as daily message counts, points and reward history, so we can run the free trial and limits.
• Purchase information. If you subscribe to Kizunami Premium, Apple or Google processes the payment. We receive the transaction details (product, purchase and expiry dates, renewal status) to verify and provide your subscription. We never receive your card details.
• Device and advertising data. Our advertising partner (Google AdMob) and analytics (Firebase Analytics) may collect device identifiers, IP address, approximate location and app interaction data. Firebase App Check verifies that requests come from the genuine app.

How we use it

• To provide chats, voice replies and loved-one conversations.
• To remember context so companions can stay consistent with you.
• To run the free trial, points and rewards, and prevent abuse.
• To show ads that help keep the app free, and to understand and improve the app.

We do not sell your personal information. We do not use your conversations or loved-one details for advertising.

Service providers

• Google Firebase (authentication, database, cloud functions, analytics, App Check).
• OpenRouter and the AI model providers it routes to (including Google Gemini), which process messages, voice and screenshots to generate replies, transcripts and speech.
• Google AdMob for ads. Where required, you will be asked for consent before personalized ads are shown. On iOS, ads use your device's advertising identifier only if you allow tracking. Premium members see no ads.
• Apple App Store and Google Play for subscription payments.

AI-generated content

Companions and loved ones are simulated by AI. Replies can be inaccurate and do not represent the views of any real person. A loved one in Kizunami is an AI reflection based on what you provided, not the person themselves.

Retention and deletion

We keep your data while your account exists. You can delete a single message, clear a chat, or delete a loved one at any time in the app. To delete everything, open My Space → Delete account. This permanently removes your account, chats, loved ones and plan data from our servers. Data on your device is removed when you delete the account or uninstall the app.

Children

Kizunami is not intended for children under 13 (or the minimum age in your country). We do not knowingly collect data from children.

Your rights

Depending on where you live, you may have rights to access, correct, delete or export your data, and to object to certain processing. Contact us and we will help.

Changes

We may update this policy. We will change the date above and, for significant changes, let you know in the app.
