Question 1

Does clausul use AI? What happens to my documents?

Accepted Answer

Yes. clausul uses AI in the comparison pipeline. Extracted change summaries are sent to Anthropic Claude to classify changes and generate review notes. Only parsed text is transmitted, never the raw document files. Anthropic operates under API terms that prohibit using customer inputs for model training.

Question 2

Are my documents used to train AI models?

Accepted Answer

No. We use the Anthropic API under terms that explicitly prohibit using API inputs and outputs for model training. Under default API terms, Anthropic may retain inputs for up to 30 days for abuse and safety monitoring, after which they are deleted. Your data is not fed back into any model. We can provide the relevant contractual references on request.

Question 3

Where is my data stored?

Accepted Answer

Infrastructure is hosted in the European Union (Germany). Uploaded documents are stored in encrypted cloud storage and automatically deleted after 14 days. Comparison results are stored in an encrypted database. All storage is subject to EU data protection law (GDPR). If your organization requires US-region hosting, contact us to discuss options.

Question 4

What data leaves the EU?

Accepted Answer

Parsed clause text is sent to Anthropic API endpoints for AI processing. Under default API terms, Anthropic may retain inputs for up to 30 days for abuse and safety monitoring, after which they are deleted. No inputs are used for model training. The raw document files, comparison results, and all other data remain within EU infrastructure. We are evaluating EU-region AI endpoints to eliminate cross-border data transfer entirely.

Question 5

How long are documents retained?

Accepted Answer

Documents automatically expire after 14 days. You can also delete a document manually at any time. When a document expires or is deleted, the uploaded files, comparison results, and all associated data are permanently removed from storage.

Question 6

Is data encrypted?

Accepted Answer

Yes. All data is encrypted in transit (TLS 1.2+) and at rest (AES-256 via cloud provider managed keys). This applies to uploaded documents, comparison results, and any data stored in the database.

Question 7

Do you support DPAs and formal procurement?

Accepted Answer

Yes. We support data processing agreements for firms and in-house teams with formal procurement requirements. We can also provide a completed vendor risk questionnaire. Contact hello@clausul.com to start the process.

Question 8

Is there an audit trail?

Accepted Answer

Yes. Document comparisons, exports, and user actions are logged for internal review and compliance workflows. Audit data is available to account administrators.

Question 9

Who can access my documents?

Accepted Answer

Only authenticated users within your organization can access your documents. clausul engineering staff do not access customer documents in the normal course of operations. Access for debugging or support purposes requires explicit authorization and is logged.

Question 10

Can I try clausul without uploading real client documents?

Accepted Answer

Yes. You can use sample documents or redacted versions to evaluate the tool before introducing client data. We recommend this as a first step for any pilot.
