The Law Society (UK) and ABA both issued 2025 guidance requiring firms to implement data minimisation before using AI on client documents. Regulators are actively auditing compliance.
Relevant Compliance Frameworks
This use case intersects with the following regulations and standards. CleanMyPrompt is a data minimisation tool — it is not a substitute for legal advice or certified compliance software.
Why this matters for Claude: Claude Enterprise provides data privacy controls but the free tier has no compliance guarantees.
What Gets Redacted — Example
This Agreement between Acme Corp (registered No. 12345678) and John Williams re: Project Phoenix valued at $2.1M.
This Agreement between [COMPANY] (registered No. [REDACTED]) and [PERSON-NAME] re: [PROJECT] valued at [FINANCIAL].
Who Uses This
- In-house counsel reviewing contracts with AI
- Law firms using AI for due diligence
- M&A teams analysing deal documents with AI assistance
The Regulatory Risk
ABA Model Rule 1.6 requires attorneys to make reasonable efforts to prevent inadvertent disclosure of client information. Submitting unredacted contracts to consumer AI tools almost certainly violates attorney-client privilege in most jurisdictions.
