Privacy Policy

Effective date: September 22, 2026 · Last updated: September 22, 2026

This Privacy Policy explains how Mosatsu (“the App”, “we”, “us”) collects, uses, stores, and shares information when you use our mobile application and related services. By using the App, you agree to this Policy.

1. Who we are

Mosatsu is an entertainment application that lets you browse fictional characters, chat with AI-powered personas, play character voice audio, send virtual gifts, and unlock characters through in-app purchases.

Operator contact for privacy requests: [email protected]

2. Information we collect

Depending on how you use the App, we may collect:

• Identifiers. A randomly generated user ID stored on your device and sent to our servers so we can associate your profile, chat history, and purchases.
• Demographics you provide. Age and gender collected during onboarding, used to tailor character suggestions and comply with age-related rules.
• User content. Messages you send, AI replies, and related chat metadata stored so conversations can be resumed across sessions.
• Usage data. Product analytics such as whether you completed onboarding, opened the main panel, opened a profile or chat, changed voice settings, sent a message, played read-aloud audio, or used translation. These flags are sticky “first reached” events.
• Network and approximate location. IP address and inferred country/city used for security, abuse prevention, and regional statistics.
• Purchase information. Product identifiers and entitlement records for one-time character unlocks. Payment card details are processed by Apple (or Google on Android) and are not collected by us.
• Device / technical data. Basic request metadata needed to deliver the service (for example, app version and network status when relevant).
• Notifications. If you grant notification permission, we may send local or server-triggered engagement notices. You can revoke permission in system settings.

3. How we use information

• Provide, maintain, and improve chat, voice (text-to-speech), translation, gifts, and character unlock features.
• Personalize character recommendations using onboarding preferences.
• Authenticate sessions, prevent fraud/abuse, and debug reliability issues.
• Measure feature funnel performance (for example, onboarding → chat → purchase).
• Process and restore in-app purchases.
• Comply with law and enforce our Terms of Use.

4. AI processing

Chat replies and spoken audio are generated using our backend AI / speech services. Message text you submit is transmitted to those systems solely to produce a response or audio for you. Do not submit sensitive personal data (passwords, financial account numbers, government IDs, precise health data, or information about others) into chat.

5. How we share information

We may share information with:

• Service providers that host infrastructure, generate AI replies, synthesize speech, or help us operate the App, under instructions to process data for us.
• Apple / Google for in-app purchase processing and store compliance.
• Legal authorities when required by law or to protect rights, safety, and security.

We do not sell personal information, and we do not share personal information for cross-app tracking advertising.

6. Data retention

We retain account, chat, analytics, and purchase records for as long as needed to provide the App and for legitimate business, security, and legal purposes. You may request deletion of your account data as described below.

7. Your choices and rights

• Access / correction / deletion. Email [email protected] with your user ID (if known) to request access, correction, or deletion of personal data we hold.
• Notifications. Control in iOS/Android system settings.
• Purchases. Manage or request refunds for Apple purchases through Apple; we cannot directly refund App Store charges.

Depending on where you live (for example, EEA, UK, California), you may have additional rights under applicable privacy laws. We will respond to verified requests within the time required by law.

8. Children’s privacy

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. The App is intended for users 17 years of age or older. If we learn that we have collected data from a user below the required age, we will delete it.

9. Security

We use reasonable administrative and technical measures to protect information. No method of transmission or storage is 100% secure.

10. International transfers

Our servers and processors may be located outside your country of residence. By using the App, you understand that your information may be transferred to and processed in those locations with appropriate safeguards where required.

11. Changes

We may update this Policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the App after an update means you accept the revised Policy.
