Privacy Policy

Version 1.0 · Effective May 30, 2026

The short version. Your matter data is yours. We never sell it, never share it with marketers, and never use it to train AI models — ours or anyone else’s. We only access your data when needed to provide the service, troubleshoot a problem you’ve reported, or as required by law.

This Privacy Policy explains how MatterEngine, Inc. (“MatterEngine,” “we,” “us”) collects, uses, and protects information when you visit matterengine.ai (the “Site”) or use our software service (the “Service”).

1. Information we collect

Information you provide

Contact information — when you request a demo, sign up, or contact us, we collect your name, work email, firm name, and any details you share in the message.
Account information — if your firm becomes a customer, we collect attorney and staff names, work emails, role, and authentication credentials.
Matter and client data — documents, client records, case status, USCIS correspondence, deadlines, billing entries, and other content you or your team upload or generate in the Service.
Payment information — handled by our payment processor (Stripe). We do not store full card numbers.

Information collected automatically

Usage logs — IP address, browser type, pages visited, actions taken in the Service, timestamps. Used for security, debugging, and product improvement.
Cookies — essential cookies for authentication and session management. We do not use third-party advertising cookies.

2. How we use information

To deliver, maintain, and improve the Service.
To communicate with you about your account, security, or product updates.
To respond to support requests and troubleshoot issues you report.
To comply with legal obligations, enforce our Terms, and protect against fraud or misuse.

We do not use your matter data, client data, or document content to train AI models — ours or any third party’s. We do not sell personal information. We do not share data with advertisers.

3. AI processing

The Service uses third-party large language model (LLM) APIs to perform tasks like drafting communications, summarizing documents, and triaging matters. When we send your content to these providers, we use APIs configured under zero-retention or no-training agreements where available. We do not allow LLM providers to use your content for model training. A current list of subprocessors is available on request.

4. Who we share information with

Service providers and subprocessors — cloud hosting (U.S. regions only), payment processing, error monitoring, customer support tools, and the AI providers described above. All are bound by contract to confidentiality and data protection terms.
Legal compliance — if required by subpoena, court order, or applicable law. We will give you reasonable advance notice unless prohibited.
Business transfers — in the event of a merger or acquisition, this Policy continues to apply to your information.

We do not sell, rent, or share your personal information for cross-context behavioral advertising.

5. Data retention

We retain customer matter and client data for as long as your firm has an active account. After termination, we retain data for up to 30 days to allow recovery, then permanently delete it from production systems. Backups are deleted on a rolling basis within 90 days. Aggregate, non-identifying usage statistics may be retained for product analytics.

6. Security

We use AES-256 encryption at rest, TLS 1.3 in transit, per-firm logical isolation, role-based access controls, and audit logging. Production access is limited to a small set of personnel with signed confidentiality obligations. We are pursuing SOC 2 Type II certification (audit in progress).

7. Your choices and rights

Depending on where you live, you may have the right to:

Access, correct, or delete personal information we hold about you.
Opt out of certain processing.
Receive a copy of your data in portable format.
Withdraw consent where processing is based on consent.

To exercise these rights, email support@matterengine.ai. We will respond within 30 days. California residents have specific rights under the CCPA / CPRA; the categories above describe our handling of personal information for purposes of those laws.

8. Attorney-client privilege

Customer matter data may include privileged attorney-client communications and attorney work product. We treat all such data as confidential, do not access it except as necessary to deliver or troubleshoot the Service (and only with appropriate authorization), and have processes designed to preserve privilege.

MatterEngine is a software vendor, not a law firm. Using MatterEngine does not create an attorney-client relationship between you and us.

9. Children

The Service is not directed to children under 16, and we do not knowingly collect personal information from them.

10. International users

The Service is operated from the United States. If you access it from outside the U.S., you understand that your information will be processed in the U.S.

11. Changes to this Policy

We may update this Policy as the Service evolves. We will post the new version here and update the “Effective” date. For material changes, we will give customers reasonable advance notice via email.
