The Justin Sun Prize (hereinafter referred to as "we" or "us") highly values your personal privacy and data protection. This Privacy Policy is designed to explain how we collect, use, store, share, and protect your personal information, as well as the legal rights you are entitled to, when you visit our official website, submit mathematical achievements, participate in evaluations, and claim prizes.

Please carefully read and understand this Privacy Policy before using this website or submitting any materials.

2. Purposes and Legal Bases for Information Processing

We collect and process your personal information primarily for the following purposes:

• Qualification Review and Evaluation: Verifying the authorship of mathematical achievements, reviewing Lean formal verification shortlisting eligibility, and processing prize evaluations.

• Official Public Disclosure: To ensure transparency and openness, publicly disclosing winner information (including winner/team names, achievement titles, and abstracts) on the official website and related public channels in accordance with rules.

• Compliance and Anti-Money Laundering (AML/KYC): Fulfilling applicable legal and regulatory obligations to conduct compliance identity screenings and prize payouts.

• Communication and Support: Maintaining necessary communications with you regarding prize progress, objection reviews, redemption instructions, and related notices.

3. Information Sharing and Public Disclosure

• Public Display: Participation in The Justin Sun Prize shall be deemed as your consent for us to publicly disclose your winning information (name/nickname, achievement abstract, and related links) on the official website and public channels.

• Service Providers and Partners: To complete identity verification or on-chain digital currency payments, we may share necessary wallet information with compliant technical service providers, auditing firms, or verification executors assisting our operations.

• Except for the aforementioned scenarios, we will not sell, rent, or illegally share your personal information with any unrelated third parties.

4. Data Security and Cross-Border Transfer

• Security Protection: We employ industry-standard administrative, technical, and physical security measures (including isolated environment verification, encrypted transmission, and secure storage) to protect your personal information against unauthorized access, modification, disclosure, or destruction.

• Cross-Border Transfer: Given the global operational nature of The Justin Sun Prize, information you submit may be transferred to and processed in the Hong Kong Special Administrative Region of the People's Republic of China or other operating jurisdictions. We will ensure that such transmission and processing comply with applicable data security protection laws.

5. Data Retention Period

We will retain your personal information for the period necessary to achieve the collection purposes outlined in this Policy, unless a longer retention period is required or permitted by laws and regulations (such as for anti-money laundering, financial auditing, or compliance archiving).
