Acceptable Use Policy

Last updated: September 22, 2026

This Acceptable Use Policy (“AUP”) is part of the Terms of Service between Proserus, Inc. and each firm that uses Proserus Legal (the “Service”). It applies to the firm and to every user the firm authorizes. Firms are responsible for their users' compliance.

1. Prohibited Uses

You may not use the Service to:

  • violate any law, regulation, court order, or rule of professional conduct;
  • infringe or misappropriate the intellectual property, privacy, or other rights of any person;
  • store or transmit malware or other harmful code;
  • send unsolicited or unlawful communications, including text messages to people who have not consented or who have opted out (see the SMS Messaging Terms);
  • harass, threaten, defame, or defraud any person;
  • process data you have no right to process, or use another person's credentials;
  • access, or attempt to access, data belonging to another firm or tenant, or any part of the Service you are not authorized to use;
  • interfere with the Service, other customers, or our infrastructure, including through denial-of-service, excessive automated requests, or circumvention of rate limits;
  • scrape, crawl, or bulk-export the Service other than through the export features provided;
  • reverse engineer, decompile, or copy the Service, or use it to build or benchmark a competing product;
  • resell, sublicense, or provide the Service to third parties other than your own clients through the client-facing features we provide;
  • use the Service on behalf of a person or organization subject to sanctions that prohibit the dealing; or
  • use AI features to generate content that is illegal, deceptive, or that impersonates a court, government body, or another person.

2. Security Testing

We welcome good-faith security research. You may test the Service's security only under the following rules:

  • test only against your own firm's account and data, or a trial account you created for that purpose;
  • do not access, modify, or delete data belonging to any other firm, and stop and report immediately if you encounter it;
  • do not run denial-of-service, load, or stress testing, and do not exceed normal usage volumes;
  • do not use social engineering, phishing, or physical attacks against Proserus staff, customers, or vendors;
  • do not test third-party services (Microsoft, Stripe, Railway, Anthropic, OpenAI, Sentry) through the Service; those have their own programs;
  • do not publicly disclose a vulnerability until we have confirmed it is fixed or 90 days have passed, whichever is first; and
  • report findings to security@proserus.com.

Research conducted within these rules is authorized under the Terms of Service, and we will not pursue legal action against you for it. Testing outside these rules is a violation of this AUP.

3. Fair Use of AI Credits

AI features are metered in credits. Plan allotments and overage rates are published on the pricing page. To keep AI features available and affordable for every firm:

  • use AI features for your firm's own legal practice, not to provide AI services to third parties or to generate content unrelated to your matters;
  • do not use scripts or automation to submit AI requests outside the interfaces and approved integrations we provide;
  • do not attempt to circumvent entitlement checks, credit metering, tier limits, or overage caps;
  • do not use the Service to extract model weights, system prompts, or to attack the AI provider; and
  • background agents are subject to the per-task autonomy limits you configure and to the platform's hard ceilings.

If a firm's usage is far outside the norm for its plan in a way that affects other customers, we may contact the firm to discuss a suitable plan and, if needed, temporarily throttle AI features. We will not throttle without notice except to protect the Service.

4. Client-Facing Features

When you use payment links, questionnaires, or text messaging, you are the sender and are responsible for obtaining any consent your clients' jurisdiction requires, for honoring opt-outs, for the content of what you send, and for directing payments to the correct trust or operating account.

5. Enforcement

We may investigate suspected violations and may remove content, suspend users or firms, or terminate accounts as described in the Terms of Service. We will give notice and an opportunity to cure where practicable, but may act immediately to prevent harm to the Service, other customers, or third parties. We may report unlawful activity to law enforcement.

6. Reporting Abuse

To report abuse of the Service, including unwanted messages sent through it, email abuse@proserus.com. For security vulnerabilities, email security@proserus.com.

7. Changes

We may update this AUP from time to time. Material changes will be announced to firm administrators at least 30 days before they take effect, and the “Last updated” date above will change.
