This Privacy Policy explains how Future Sense Tech (Hong Kong) Limited ("Halluna", "we", "us", or "our") collects, uses, shares, and protects information when you use the Halluna mobile application and related services (the "Service"). By using the Service, you agree to the practices described in this policy.

1. Information We Collect

We collect the following categories of information:

• Account information. Such as your email address, username, sign-in identifiers (e.g., Apple or Google sign-in), and any profile details or preferences you provide.
• Conversation content. The messages, prompts, and content you send to and receive from your AI companion in order to provide and improve the Service.
• Usage and device information. App interactions, feature usage, session times, device model, operating system version, language, app version, and general (non-precise) location inferred from your IP address.
• Purchase information. If you buy a subscription or in-app product, the transaction is processed by the Apple App Store or Google Play. We receive confirmation of the purchase and subscription status, but we do not collect or store your full payment card details.
• Support communications. Information you provide when you contact us for customer support or feedback.

2. How We Use Information

We use the information we collect to:

• Provide, operate, and maintain the Service and your AI companion experience;

• Improve, troubleshoot, and develop new features;
• Maintain safety, prevent fraud and abuse, and enforce our Terms of Service;
• Respond to your requests and provide customer support;
• Comply with applicable legal obligations.

3. AI Conversations

Halluna uses artificial intelligence to generate responses. Your messages are processed to produce replies and to maintain conversational context. To deliver this functionality, conversation content may be processed by trusted third-party AI infrastructure providers acting on our behalf under contractual confidentiality and data-protection obligations.

4. How We Share Information

We do not sell your personal information. We share information only as described below:

• Service providers. With vendors who help us operate the Service (e.g., cloud hosting, AI processing, analytics, and customer support), who are permitted to use the data only to perform services for us.
• App stores & payment processors. Apple and Google process purchases and subscriptions according to their own privacy policies.
• Legal and safety. When required to comply with law, legal process, or a government request, or to protect the rights, safety, and security of our users, the public, or us.
• Business transfers. In connection with a merger, acquisition, financing, or sale of assets, subject to this Privacy Policy.

5. Data Retention

We retain your information for as long as your account is active or as needed to provide the Service, and thereafter only as required to comply with legal obligations, resolve disputes, and enforce our agreements. When you delete your account, we delete or de-identify your personal information within a commercially reasonable period, except where retention is required by law. See Delete Account & Data for details.

6. Your Rights & Choices

Depending on where you live, you may have rights to access, correct, delete, or export your personal information, to object to or restrict certain processing, and to withdraw consent. These rights apply, among others, to residents of the European Economic Area and the United Kingdom (GDPR) and California (CCPA/CPRA).

• Access & portability. Request a copy of the personal data we hold about you.
• Correction. Update inaccurate or incomplete information.
• Deletion. Delete your account and associated data at any time from within the app or via the steps on our Delete Account & Data page.
• Opt-out. Manage notifications and certain data uses through your device or account settings.

To exercise any of these rights, contact us at [email protected]. We will respond consistent with applicable law and may need to verify your identity.

7. Data Security

We use administrative, technical, and organizational measures designed to protect your information, including encryption in transit and access controls. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Halluna is intended for users aged 16 and over and is not directed to children under the age of 16. We do not knowingly collect personal information from anyone under 16. If you believe a child under 16 has provided us with personal information, please contact us so we can remove it.

9. International Data Transfers

We are based in Hong Kong and may process and store information in Hong Kong and other countries where we or our service providers operate. These countries may have data-protection laws different from those in your jurisdiction. Where required, we implement appropriate safeguards for such transfers.

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, provide additional notice within the app. Your continued use of the Service after changes take effect constitutes acceptance of the updated policy.
