Privacy Policy

Yuki Chat ("the App", "we", "us", "our"), operated by Tranquil Mind Technology JSC, respects your privacy. This Privacy Policy explains what information we collect, how we use and share it, and the choices and rights you have. By using the App, you agree to this Policy.

Yuki Chat is an AI companion chat app where adults converse with AI characters by text and voice in 8 languages. You do not need to create an account to use it; your chat history is stored locally on your device.

1. Information We Collect

You do not create an account, and we do not ask for your real name, email address, or phone number to use the App. We collect the following:

• Messages you send to AI characters. The text of your chats is transmitted to our AI provider (DeepSeek) to generate replies. Your chat history is also stored locally on your device.
• Device and advertising identifiers (e.g. Android advertising ID, device/app instance identifiers).
• Approximate location derived from your IP address by our advertising and analytics partners (not GPS/precise location).
• App activity — how you interact with features, screens viewed, and similar usage events.
• Crash logs and diagnostics — technical data to keep the App stable.
• Purchase status — whether you hold a subscription (processed by Google Play Billing; we do not receive your card details).
• Voice input — if you use voice-to-text, audio is processed by your device's operating-system speech recognizer to produce text; we do not store your voice recordings on our servers.
• Read-aloud text (text-to-speech). When you have a message read aloud, the message text is sent to the Google Cloud Translation API to detect its language so we can select the correct voice; speech is then synthesized on your device.
• Profile photo — if you set an avatar, the image is selected from your device and kept locally; it is not uploaded to our servers.

We only collect data that leaves your device as described above.

2. How We Use Information

• Provide and operate the App and generate AI replies.
• Personalize and remember your in-app preferences.
• Serve and measure advertising.
• Analytics and product improvement.
• Fraud prevention, security, and compliance.
• Process and validate purchases.
• Comply with legal obligations.

3. Third-Party Services

The App integrates the following data-transmitting services. Each processes data under its own privacy policy:

4. How We Share Information

We do not sell your personal information for money. We share the data above with the third-party services listed in §3 for the purposes described. We may also disclose information for legal reasons (to comply with law or protect rights and safety) or as part of a business transfer. Because our advertising partners may use identifiers for personalized advertising, some U.S. state laws may treat this as a "sale" or "sharing" of personal information; you can opt out using the device advertising-ID controls above and any in-app/consent choices.

5. Legal Bases (EEA/UK — GDPR)

• Consent — for personalized advertising and analytics where required.
• Legitimate interests — core functionality, security, and improvement.
• Contract / legal obligation — to process purchases and comply with law.

6. Data Retention

We keep data only as long as necessary for the purposes above or as required by law. Advertising/analytics identifiers are retained per each partner's retention periods; crash and diagnostic data are kept for a limited period. Chat history stored locally remains on your device until you delete it or uninstall the App.

7. Your Rights

• GDPR (EEA/UK): access, correct, delete, port, object, restrict, withdraw consent, and complain to a data protection authority.
• CCPA/CPRA (California): know, delete, correct, opt out of sale/sharing and targeted advertising, and non-discrimination.
• Other regions: LGPD (Brazil), PIPEDA (Canada), and similar laws provide comparable rights.

To exercise these rights, contact us at the email below. Because the App has no account, please include your device advertising ID and relevant details so we can identify the data.

8. Children's Privacy & Child Safety Standards

Yuki Chat is intended for users aged 18 and older. The App is not directed to children, and we do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.

This section is our published Child Safety Standards for Yuki Chat, in line with the Google Play Child Safety Standards policy and applicable law.

Zero-tolerance prohibition of CSAE

We strictly prohibit, and have zero tolerance for, any content, conduct, or communication that sexually abuses, exploits, or endangers children, including but not limited to:

• Child Sexual Abuse Material (CSAM) in any form — images, video, audio, text, or AI-generated content.
• Sexualization of minors, including sexualized or suggestive content depicting or describing anyone under 18.
• Grooming, sextortion, solicitation, or trafficking of minors.
• Any attempt to use the App to create, request, share, promote, or facilitate access to such material.

This prohibition applies to all users, all user-provided input, and all AI-generated content produced within the App.

How we prevent and address CSAE

• Content standards & moderation. Our AI characters are configured with safety instructions that refuse to generate sexual or exploitative content involving minors, and prohibited content is blocked. Conversations reported to us are reviewed against these standards.
• In-app reporting. Users can report content or behavior that may involve a child-safety concern from within the App and by emailing our child-safety contact below. Every report is reviewed.
• Action on violations. We remove prohibited content, suspend or terminate the responsible access, and preserve relevant information as permitted by law.
• Reporting to authorities. We report apparent CSAM to the National Center for Missing & Exploited Children (NCMEC) and/or the appropriate local authorities, and cooperate with law enforcement as required by applicable law.

Compliance. We comply with applicable child-safety laws in the jurisdictions where the App is available and align our practices with the Google Play Child Safety Standards policy.

9. International Data Transfers

Your data may be processed outside your country, including in the United States and other jurisdictions where our providers operate. Where required, we rely on appropriate safeguards (e.g. Standard Contractual Clauses).

10. Data Security

We use encryption in transit (HTTPS/TLS) and reasonable technical and organizational measures to protect data. No method of transmission or storage is 100% secure.

11. AI-Generated Content

Replies are generated by AI and may be inaccurate or unexpected. Do not share sensitive personal information in your chats. AI content is for entertainment and general information only and is not professional advice.

12. Changes to This Policy

We may update this Policy. Material changes will be posted with a new "Last updated" date; continued use of the App means you accept the revised Policy.
