Xuzo App Privacy Policy

This Privacy Policy ("Policy") explains how we ("we", "us", or "our") collect, use, store, and protect information when you ("you", "your") access or use Xuzo ("the App"), a niche unit conversion and knowledge popularization tool. By using the App, you acknowledge that you have read, understood, and agreed to the practices described in this Policy. We adhere to the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and other applicable global privacy laws to safeguard your information.

1. Information We Collect

The App is available for use without registration or login, so we do not collect or store your personal identification information (e.g., name, email address, phone number, username, or government-issued identifiers). We only collect non-personal data ("Non-Personal Data") that does not identify you individually, including but not limited to:

Device information: Such as device model, operating system version, and unique device identifiers (e.g., IDFA, Android ID) solely for compatibility and performance optimization.
Usage statistics: Including features accessed, conversion history (anonymous), session duration, and error logs to improve the App's functionality and user experience.
Technical data: Such as network type (Wi-Fi/cellular) and regional location (general area, not precise GPS coordinates) to ensure stable service delivery.

We never collect sensitive personal information (e.g., biometric data, financial information, health records) under any circumstances.

2. How We Use Collected Information

We use Non-Personal Data exclusively for the following legitimate purposes, in line with the principle of minimal necessity:

Optimize App performance: Identify and fix technical issues, improve loading speed, and ensure compatibility with different devices and operating systems.
Enhance user experience: Analyze usage patterns to refine existing features, add new niche unit conversion tools, and tailor content to user needs.
Ensure service security: Detect and prevent fraudulent or abusive use of the App, and protect the App from unauthorized access or attacks.

We will not use your information for marketing, advertising, or any other purposes not explicitly stated in this Policy.

3. Information Sharing and Disclosure

We respect your privacy and will never sell, rent, or trade your Non-Personal Data to third parties for commercial purposes. We may disclose information only in the following limited circumstances:

Legal requirements: If compelled by law, court order, or regulatory authority to disclose information to comply with applicable laws and regulations.
Service providers: We may engage trusted third-party service providers to assist with App operation (e.g., analytics tools, server hosting). These providers are bound by strict confidentiality agreements and may only use information to perform services on our behalf.
Business transfers: In the event of a merger, acquisition, or sale of all or part of our assets, Non-Personal Data may be transferred as part of the transaction, with prior notice to users where required by law.

4. Data Storage and Protection

4.1 Storage Period

We retain Non-Personal Data only for as long as necessary to fulfill the purposes outlined in this Policy, or as required by law. Once the data is no longer needed, we will securely delete or anonymize it to prevent identification.

4.2 Security Measures

We implement appropriate technical and organizational security measures to protect Non-Personal Data from unauthorized access, disclosure, alteration, or destruction. These measures include data encryption, secure server storage, access control, and regular security audits. However, no internet service is completely secure, and we cannot guarantee absolute protection against all potential threats.

5. Your Data Rights

In accordance with applicable privacy laws, you have the following rights regarding your information. To exercise these rights, please contact us at the provided email address:

Right of access: Request confirmation of whether we hold any data related to you and obtain a copy of such data.
Right to erasure: Request the deletion of any data we hold about you, subject to legal retention requirements.
Right to rectification: Request correction of any inaccurate or incomplete data we hold about you.
Right to withdraw consent: Since we do not collect personal data requiring explicit consent, you may stop data collection by uninstalling the App at any time.

We will respond to your request within a reasonable timeframe, as required by law, and may ask for verification to ensure the request is legitimate.

6. Policy Updates

We reserve the right to update or modify this Policy from time to time to reflect changes in laws, regulations, or App functionality. When we make material changes, we will notify you through a prominent notice within the App (e.g., pop-up message) and update the effective date at the top of this Policy. Your continued use of the App after the updated Policy takes effect constitutes acceptance of the new terms.

7. Children's Privacy

The App is not intended for use by children under the age of 13 (or the minimum age required by local law). We do not knowingly collect any information from children. If we become aware that we have collected information from a child, we will immediately delete it and terminate access to the App for that user.

8. Governing Law

This Policy shall be governed by and construed in accordance with the laws of England and Wales (for EU users) and the State of California, USA (for US users), excluding conflict of law principles. Any disputes arising from this Policy shall be resolved in accordance with the dispute resolution provisions in the Xuzo App User Agreement.

9. Miscellaneous

This Policy is an integral part of the Xuzo App User Agreement. If any term of this Policy is deemed invalid or unenforceable, the remaining terms shall remain in full force and effect. This Policy constitutes the entire understanding between you and us regarding data privacy in relation to the App.
