Law Enforcement Guidelines

These guidelines are for law enforcement and other government agencies asking for information about Cotrest users. Cotrest is operated by Juschin Labs, a company in Brentwood, California, United States. Users can read this page too: it explains when we disclose data and when we tell you about it. It isn't legal advice and doesn't create rights for anyone.

Our approach

We disclose user information only in response to valid legal process, or in an emergency involving an imminent risk of death or serious physical injury. We review every request, ask for clarification when a request is unclear, and narrow or decline requests that are overbroad or not legally valid. We follow the US Stored Communications Act and, for California government entities, the California Electronic Communications Privacy Act.

How to submit a request

Email legal@cotrest.com from an official government email address, with "Law enforcement" in the subject line. We don't accept requests through the support form, the report form or social media. Please include:

What legal process we need

Requests from outside the United States should come through a mutual legal assistance treaty, letters rogatory or another process recognised under US law. We may respond directly to genuine emergencies from any country.

What we can provide

We deliver records as a ZIP file with a README, a manifest of SHA-256 checksums, data in JSON and CSV, and a merged timeline in UTC. A records custodian declaration is available on request.

What we can't provide

Emergency requests

If there is an imminent risk of death or serious physical injury, email legal@cotrest.com with "EMERGENCY" in the subject. Tell us the nature of the emergency, who is at risk, how the information requested would help, and how to reach the requesting officer. We may disclose information without legal process if we believe in good faith that the emergency is real and the information will help. We check the legal inbox regularly, including for emergencies, but can't guarantee a response time. If someone is in immediate danger, contact local emergency services first.

Preservation requests

On a valid preservation request (for example under 18 U.S.C. § 2703(f)) we keep a copy of the account's existing data for 90 days, and for one further 90-day period if you renew the request. Preservation stops the data from being deleted, including by the user's own deletion request, but we don't disclose preserved data without valid legal process.

Telling users

We tell users before we disclose their information, so they can seek legal advice or challenge the request. We don't give notice when the law prohibits it (for example a nondisclosure order under 18 U.S.C. § 2705(b)), in emergencies, in child-safety matters, or when notice would be counterproductive, for example because it would put someone at risk. When a nondisclosure order ends, we may notify the user then.

Child safety

We report apparent child sexual exploitation to the National Center for Missing & Exploited Children (NCMEC), as US law requires, and preserve the related data.

Costs

We may ask for reimbursement of reasonable costs where the law allows.

Transparency reporting

We plan to publish the number of government requests we receive, by type and country, and how we responded, as part of our transparency reporting. We won't include details that identify an investigation.
