1. Submit a request
Email msfc136@163.com and specify the data you wish to access, correct or delete. A visible invitation code, relevant order number or incident time may help verification. Do not send authentication credentials, passwords or purchase tokens.
Data requests may concern two-person chats, group membership, device anti-abuse data and purchase records. Explain your request and provide relevant group information or order numbers for verification; do not send invitation tokens, purchase tokens or keys. Local deletion, leaving or dissolving a group does not simultaneously erase all related server data or other members’ copies.
2. Scope
We verify ownership and explain what can be handled and what must be retained for applicable obligations, financial records or anti-abuse purposes. Clearing local history does not erase server ledgers or the other participant’s copy. This version has no registered login account or cross-device recovery. Do not uninstall first merely to request deletion, as this may remove information needed for verification.
