Privacy Policy

Kairo 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.

Kairo Chat is an AI companion chat app where you converse — by text or voice — with AI characters whose personality you can customize. You do not need to create an account to use it.

1. Information We Collect

Data you provide that stays on your device

Your profile details (display name, gender, age, and an optional email address you may enter) and your chosen avatar are stored locally on your device only and are not transmitted to our servers. You do not create an account, and we do not verify or use the email address to contact you.

Content you send to the AI

When you chat, the text of your messages is sent to our AI provider (DeepSeek) to generate a reply. If you use voice-to-text, your speech is converted to text on your device by your operating system's speech recognition; we do not upload voice recordings. The resulting text may then be sent as a message as described above.

When you use the text-to-speech ("read aloud") feature, the text being read is sent to Google's Cloud Translation service to automatically detect its language so it can be spoken with the correct voice. Because chat text can be sensitive, please avoid sharing information you do not want processed by these AI and language services.

Data collected automatically

Through the third-party services below we (and they) collect:

• Device and advertising identifiers (including the Android Advertising ID);
• Approximate location derived from your IP address (for advertising);
• App activity — in-app interactions and events;
• Crash logs and diagnostics (performance data);
• Purchase status for subscriptions bought through Google Play Billing.

We do not collect precise GPS location, your contacts, or your photo library.

2. How We Use Information

• Provide and operate the App and its AI chat features;
• Personalize your experience and remember your preferences;
• Show advertising and measure its performance;
• Analytics, diagnostics, and improving the App;
• Fraud prevention, security, and compliance;
• Process purchases and manage subscriptions;
• Comply with legal obligations.

3. Third-Party Services

4. How We Share Information

We do not sell your personal information for money. We share data with the third-party services listed above so they can perform their functions, for legal reasons (to comply with law or protect rights), and in a business transfer (merger/acquisition). Because we serve personalized ads, some U.S. state privacy laws may treat this ad-related data use as a "sale" or "sharing" for targeted advertising — you may opt out as described in Sections 3 and 7.

5. Legal Bases (EEA/UK — GDPR)

• Consent — personalized ads and analytics where consent is required;
• Legitimate interests — core functionality, security, and improvement;
• Contract / legal obligation — processing purchases and meeting legal duties.

6. Data Retention

We keep data only as long as necessary for the purposes above or as required by law. Advertising and analytics identifiers are retained per each partner's retention periods; crash and diagnostic data are kept for a limited period. Locally stored profile data 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 (e.g. LGPD, PIPEDA): equivalent rights may apply.

To exercise these rights, contact us at contact@tranquilmind.co. Because the App has no account, please include your Advertising ID and device details so we can locate any associated data.

8. Children's Privacy & Child Safety Standards

The App is intended for users 18 years of age and older and is not directed to children. We do not knowingly collect personal information from children. If we learn that a child has provided personal information, we will delete it.

Child Safety Standards (CSAE)

This section is the published Child Safety Standards for Kairo Chat, operated by Tranquil Mind Technology JSC, referenced from Google Play. Child-safety point of contact: contact@tranquilmind.co.

We have zero tolerance for child sexual abuse and exploitation (CSAE) and child sexual abuse material (CSAM). This zero-tolerance standard covers images, video, audio, text, and AI-generated content, and applies to both what you send to the App and what the AI produces. Specifically, we prohibit any content or conduct that:

• sexualizes, exploits, or endangers a minor;
• constitutes grooming, sextortion, solicitation, or trafficking of a minor;
• attempts to create, request, share, or promote CSAE/CSAM, including through prompts to the AI.

Our prevention and response measures:

• The App does not provide any user-to-user messaging, sharing, or discovery — all conversations are between you and an AI character, so there is no channel to share CSAM with other users.
• We instruct our AI system to refuse to generate sexual content involving minors and to reject any request that seeks CSAE/CSAM.
• Users can report suspected CSAE or a harmful AI response by emailing our child-safety contact at contact@tranquilmind.co; we review reports and, where a violation is confirmed, remove offending content and suspend access.
• We report apparent CSAM to the National Center for Missing & Exploited Children (NCMEC) and/or the appropriate local authorities, as required by law.

We comply with applicable child-safety laws and align these standards with the Google Play Child Safety Standards policy.

9. International Data Transfers

Your information may be processed in countries other than your own, including the United States. Where required, we rely on appropriate safeguards (such as Standard Contractual Clauses).

10. Data Security

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

11. Third-Party Content

The App displays advertising and AI-generated content, and may link to third-party sites. We are not responsible for third-party content or practices; please review their policies.

12. Changes to This Policy

We may update this Policy from time to time. Material changes will be posted with a new "Last updated" date. Continued use of the App after changes means you accept the updated Policy.
