We do not share, transfer, or publicly disclose your personal information except in these cases.

(b) Transfer: only in the case of merger, acquisition, or asset sale, in which case we will notify you and require the new operator to honour this policy. (c) Disclosure: not disclosed publicly, except where legally required. (d) Cross-border transfer: servers are located in the People's Republic of China; your data does not leave the country by default. Should cross-border transfer become necessary, we will obtain your separate consent and complete the legally required security assessments.

Storage location: servers located in the People's Republic of China. Retention: · While the account is active: we retain your registration and gameplay data; · After account deletion: personal information will be deleted or anonymized within 30 days, unless required to be kept by law; · Logs related to transactions, security, or disputes may be retained up to 3 years where required by law.
