1. Introduction
Services related to Ju.com are provided by multiple entities within their respective compliance scopes (see Terms of Service for details). These entities are hereinafter collectively referred to as “we” or “Ju.com.”
We are committed to reviewing law enforcement requests on a case-by-case basis and providing assistance in accordance with applicable laws and regulations, the Terms of Service, and Privacy Policy, provided that the requesting party has lawful authority and can provide adequate proof of authorization and compliant legal documents (e.g., requests for user information, account restrictions or freezes, data preservation, etc.).
For cross-border law enforcement requests, submission is generally required through formal channels such as Mutual Legal Assistance Treaties (MLAT), letters rogatory, or court cooperation letters.
Important Note:
We only respond to compliant requests issued by authorized law enforcement agencies. We do not process information requests from private parties or civil dispute litigants.
2. Submission Methods
Please submit law enforcement requests via the following dedicated channel (use an official domain email address whenever possible):
Dedicated Law Enforcement Email: legalaid@ju.com
Suggested Email Subject Format:
[Urgent/Standard] | Full Name of Organization | Case Number | Request Type (e.g., Evidence Collection / Freeze / Preservation / Other)
We will conduct a written review of requests in accordance with laws, regulations, and internal procedures, and perform necessary telephone verification. If the materials are incomplete or the law enforcement authority is unclear, we may request additional explanations or decline the request.
3. Required Materials and Information
To enhance processing efficiency, please ensure your email includes the following materials and information (it is recommended to send from a government domain email, or to provide written authorization from the government domain email to the officer’s personal email):
A. Authorization and Legal Documents
Case filing decision or acceptance receipt related to the case;
An official, stamped written law enforcement request letter (e.g., “Notice of Assistance in Evidence Collection,” “Notice of Assistance in Asset Freeze,” etc.);
Clear legal basis and applicable clauses (e.g., specific articles of the Criminal Procedure Law, court rulings, prosecutor’s orders, etc.);
For cross-border requests, please attach relevant documents or explanations showing submission through MLAT or judicial cooperation channels.
B. Law Enforcement Officer Identity Verification
At least two law enforcement officers’ work ID copies or scans;
Official contact information: agency email, publicly verifiable office landline, work mobile phone;
Preferred time slots for telephone verification (please indicate the time zone).
C. Request Target and Scope (must follow the principles of specificity, precision, and minimal necessity)
Ju.com account information: UID (if available), registered email, linked mobile number, KYC-verified name;
On-chain information: cryptocurrency address (Address), transaction hash (TXID), deposit/withdrawal addresses, associated tags (Tag/Memo);
Timeframe: specify the start and end times in Coordinated Universal Time (UTC);
Device and network information (if requested): login IP address, device ID/fingerprint, geographic location (if legally permitted to provide);
Specific request items: information retrieval / account restriction / asset freeze / data preservation / other;
Supporting materials: brief case description, fund flow diagram, relevant screenshots, police report, etc.
Please note: Ju.com will assess the final scope and content of assistance based on legality and the principle of minimal necessity.
4. Urgent Law Enforcement Requests
For situations involving significant personal safety or ongoing asset transfers/theft requiring immediate account restrictions or data preservation, please indicate “Urgent” in the email subject and detail the urgent circumstances and legal basis in the body. We will make every effort to prioritize and expedite processing.
On-platform assets: Where legal conditions are met, we may evaluate and implement temporary restrictions or freezes.
On-chain assets: We have no authority to unilaterally freeze digital assets already on-chain, but can, within legal limits, assist in tagging risk addresses, cooperate in tracking, and provide leads.
Recommendation: Simultaneously contact relevant blockchain analytics companies, security firms, and other exchanges for coordinated action.
5. Cross-Border Requests and Mutual Legal Assistance
If a request is submitted by a foreign law enforcement agency and involves entities or user data located in other countries/regions, submission is generally required through formal channels such as MLAT or letters rogatory. If cross-border legal requirements are not met, we may only provide general information or may have to decline the request.
6. Data Preservation
If temporary preservation of user data is needed prior to formal legal proceedings, please clearly indicate “Data Preservation” in the request and specify the scope and anticipated duration.
Where permitted by law, we may, per internal policies, temporarily preserve data (generally up to 90 days, extendable if allowed by law). If formal legal documents are not received before expiration, the preserved data may be deleted or revert to routine processing.
7. Circumstances Under Which Requests May Be Declined
Requests may be declined under the following circumstances, including but not limited to:
The requesting organization cannot prove lawful authority, or law enforcement officers’ identities cannot be verified;
Insufficient legal basis, incomplete documentation, missing official stamps, or clear overreach of authority;
Request scope is overly broad, vague, or not in line with the principle of minimal necessity;
Cross-border requirements are incomplete (not submitted through formal MLAT channels, etc.);
Request content is irrelevant or clearly contradictory to the described case;
Information requests from civil dispute litigants or private parties;
Other circumstances violating applicable laws/regulations or conflicting with Ju.com policies.
8. Privacy and User Notification
We will strictly process data in accordance with applicable laws and privacy policies, and will implement de-identification and data minimization measures where permitted by law.
Unless expressly prohibited by legal documents or where notification would hinder investigation, we will notify affected users to the extent permitted by law and where it does not impede law enforcement actions.
9. Language and Format Requirements
Accepted Languages: Chinese or English (for other languages, a certified translation must be provided).
Document Format: PDF is recommended (documents should bear official seals or valid electronic signatures); if containing sensitive information, please encrypt.
Time Notation: Please use Coordinated Universal Time (UTC) to avoid ambiguity.
10. Disclaimers and Reservations
We make no guarantees regarding response time; processing speed depends on the completeness of legal requirements and case complexity.
We reserve the right, within legal limits, to charge reasonable costs and fees (if applicable, prior notice will be given).
These Guidelines will be updated periodically in accordance with changes in laws and policies. If there is any conflict between this document and applicable laws, regulations, or effective judicial documents, the applicable laws, regulations, and judicial documents shall prevail.
