MixCall — Law Enforcement Guide
Law Enforcement Guide
1. Introduction
MixCall is a 18+ anonymous video-chat application operated by an independent developer based in Islamabad, Pakistan. We are committed to cooperating with lawful law-enforcement requests while rigorously protecting the privacy rights of our users.
We respond only to requests that comply with applicable law. Every request is reviewed to confirm legal sufficiency before any data is disclosed. We object to requests that are overbroad, not legally valid, or conflict with our users' fundamental rights.
This guide explains what data we can provide, how to submit a request, and what to expect from us.
2. Types of Requests Accepted
We accept and process the following categories of legal requests:
| Request Type | Description |
|---|---|
| Subpoena | Compels production of non-content records (account metadata, IP logs, device IDs) |
| Court Order | Judicial order requiring disclosure of specified data; we may require additional legal authority depending on data sensitivity |
| Search Warrant | Compels production of content data (chat messages, call metadata) where supported by probable cause |
| Preservation Order | We will preserve specified user data for 90 days pending formal legal process |
| Emergency Disclosure | Voluntary disclosure where we have a good-faith belief of imminent risk to life — no formal process required (see Section 6) |
| MLAT / Letter Rogatory | International requests processed via the appropriate bilateral treaty or diplomatic channel |
3. Data MixCall Can Provide
Subject to a valid legal request, we may be able to provide the following categories of data:
- Account / Profile: Display name, self-reported gender, self-reported date of birth
- Device identifiers: Device ID (Android ID / Firebase Installation ID), app version, operating system version, device model
- Network metadata: IP address at account creation and at last login (as retained by Firebase)
- Call metadata: Call duration logs (timestamps, duration in seconds). No audio or video is ever stored.
- Chat messages: Text messages where retained in our database at the time of the request
- Session metadata: Login timestamps, session identifiers
- Crash / diagnostic logs: Firebase Crashlytics logs linked to a device
- Account status: Active, suspended, or deleted; reason for suspension if applicable
4. Data MixCall Cannot Provide
We are unable to provide the following, and will decline any request seeking these items:
| Data Category | Reason |
|---|---|
| Video / audio recordings | MixCall uses WebRTC for live peer-to-peer calls. No video or audio is ever transmitted to or stored on our servers. |
| Email addresses | MixCall does not require or collect email addresses. Anonymous guest login only. |

| GPS / precise location | We do not collect precise geolocation. Country-level region may be inferred from IP address only. |
| Third-party SDK data | Data held by TikTok SDK, Meta Audience Network, or CAS.ai is not in our custody. Contact those providers directly. |
5. Submission Requirements
All legal requests must be submitted in writing. We do not accept verbal requests or informal inquiries. To submit a request:
Contact
Email: v4andro@gmail.com
Subject line format: Law Enforcement Request — [Jurisdiction] — [Case Reference Number]
Mailing address: Civic Center, Bahria Town, Islamabad, Pakistan
Required Information
Every request must include:
- Full name and badge/ID number of the requesting officer
- Name and address of the law enforcement agency
- Official agency email address and direct phone number
- Case or investigation reference number
- Legal authority for the request (e.g., statute, court order number, warrant number)
- Specific data categories requested — be as precise as possible
- User identifier(s) — MixCall User ID, device ID, IP address, or other identifier to locate the account
- Relevant date/time range for the data requested
- Certified copy of the legal instrument (subpoena, warrant, court order, etc.) as an attachment
6. Emergency Disclosure
If you have a credible, good-faith belief that there is an imminent threat to the life or physical safety of a person, you may request emergency disclosure without a formal legal instrument.
To submit an emergency request:
- Email: v4andro@gmail.com
- Subject line:
EMERGENCY REQUEST — [Brief Description] - Include: nature of the emergency, specific user identifier(s), and your direct contact number
We will review emergency requests immediately and respond as quickly as operationally feasible. Emergency disclosure is voluntary and reserved for genuine life-safety situations. We reserve the right to follow up with formal legal process after the emergency has passed.
False or bad-faith emergency requests may be reported to the relevant oversight authority.
7. Child Safety & CSAM
Any law enforcement request relating to child sexual abuse material (CSAM) or child sexual exploitation and abuse (CSAE) will be treated as the highest priority and escalated immediately.
MixCall maintains a zero-tolerance policy for CSAM and CSAE. Regardless of the user's location or nationality:
- All apparent CSAM is reported to the National Center for Missing & Exploited Children (NCMEC) CyberTipline as required by 18 U.S.C. § 2258A
- Accounts involved in CSAM or CSAE are immediately suspended pending investigation
- We proactively cooperate with NCMEC, law enforcement agencies, and child safety organizations
- CSAM-related law enforcement requests receive priority review and expedited response
To report child safety matters or submit a CSAM-related law enforcement request, use the emergency contact channel above with subject line: CSAM — LAW ENFORCEMENT REQUEST
Members of the public who observe child safety violations within MixCall should use the in-app report button or contact us at v4andro@gmail.com.
8. User Notification
MixCall's default policy is to notify users when we receive a legal request that concerns their account, prior to complying, so they have the opportunity to seek legal counsel if they wish.
We will not provide prior notice if:
- We are legally prohibited from doing so (e.g., by a court-ordered non-disclosure or gag order)
- The request involves an ongoing criminal investigation and prior notice would jeopardise it
- The request involves a child safety emergency
- Notice would create a risk of imminent harm
We may notify the user after disclosure if a previously applicable restriction is later lifted. We reserve the right to seek modification or vacation of non-disclosure orders where legally permissible.
9. Data Preservation
Upon receipt of a valid preservation request, MixCall will preserve specified user data for 90 days while you obtain formal legal process.
- Preservation requests must identify the user account and data categories to be preserved
- Extensions beyond 90 days are available upon request and subject to operational review
- Preserved data is held securely and disclosed only upon receipt of valid legal process
- We do not proactively extend preservation beyond the requested period without further legal instruction
Preservation requests should be sent to v4andro@gmail.com with subject: Data Preservation Request — [Case Reference]
10. Governing Law
MixCall is operated under the laws of the Islamic Republic of Pakistan. All legal disputes and requests are governed by Pakistani law, with jurisdiction in the courts of Islamabad.
International Requests
Law enforcement agencies from outside Pakistan may submit requests via:
- Mutual Legal Assistance Treaty (MLAT) — through the appropriate bilateral treaty channel between Pakistan and the requesting country
- Letter Rogatory — through diplomatic channels where no MLAT exists
- Direct submission — for emergency requests or where MLAT is impractical, subject to our review for legal sufficiency under applicable law
We evaluate international requests on a case-by-case basis and may require local legal authority or authentication depending on the nature of the request.
11. Response Timeline
| Request Type | Target Response Time |
|---|---|
| Standard legal process (subpoena, court order, warrant) | 14 – 30 business days from receipt of complete request |
| Preservation request | 3 – 5 business days acknowledgement; preservation begins immediately |
| Emergency disclosure | Within hours where operationally feasible |
| CSAM / child safety | Highest priority — same-day acknowledgement where possible |
Response times are targets, not guarantees. Complex requests or high-volume periods may require additional time. We will acknowledge receipt of all requests within 2 business days and communicate estimated timelines where processing will exceed 14 days.
