Privacy Policy
Last updated: June 2026
"Your contract text is never stored. We never train AI on your data. We never sell your information. This is not a legal disclaimer buried in fine print — it is the foundation of what Klause AI is built on."
What data we collect
When you use the free analyzer: we collect no personal data. Contract text is processed in memory and immediately discarded — never written to any database or log file.
When you create an account: we collect your email address and subscription status only. We do not collect payment card details (handled entirely by Stripe).
Usage data: we collect anonymized analytics (page views, feature usage) via privacy-first analytics. No personally identifiable information is included.
What we do NOT do
We do not store your contract text on our servers.
We do not train AI models on your contract data.
We do not sell, share, or rent your data to third parties.
We do not use cookies for advertising or cross-site tracking.
How contract analysis works
When you submit a contract for analysis, the text is transmitted via encrypted HTTPS connection to our AI provider (Anthropic) for processing. The response is returned to your browser. Neither Klause AI nor our AI provider retains the contract text after the analysis is complete. Uploaded PDF files are stored temporarily on Vercel Blob storage and automatically deleted within 24 hours.
Data retention
Account data (email, subscription status): retained until you delete your account.
Analysis history (Pro users): retained until deleted by you or account closure.
Contract text: never retained — processed and discarded immediately.
Upload files: auto-deleted within 24 hours.
Your rights (GDPR)
You have the right to: access the personal data we hold about you; correct inaccurate data; request deletion of your account and all associated data; export your data in a machine-readable format; withdraw consent at any time.
To exercise any of these rights, contact us at hello@klauseai.com. We will respond within 30 days.
Cookies
We use strictly necessary cookies only: session authentication for logged-in users, and a single analytics cookie (no PII). We do not use advertising or third-party tracking cookies.
