2. What Data We Collect

2.1 Anonymous users (no account)

  • Contract text: Transmitted to our AI provider and immediately discarded. Never written to any database or log.
  • IP address (hashed): Used solely for rate limiting (3 free analyses/day). Auto-purged after 24 hours.
  • Anonymized analytics: Page URL, referrer, country-level geolocation only. No personal data. No cross-site tracking.

2.3 What we do NOT collect

  • Payment card numbers (handled entirely by Stripe — we never see them)
  • Your contract text for storage, training, or any purpose beyond immediate analysis
  • Biometric data, health data, or GDPR special-category data
  • Location data beyond country-level
  • Data from children under 16 (see Section 11)

3. How Contract Analysis Works — Technical Disclosure

When you submit a document, the following data flow occurs:

  1. Your document is transmitted via encrypted HTTPS (TLS 1.3) to Klause AI servers hosted on Vercel.
  2. The text is forwarded via encrypted API to OpenRouter, which routes it to an underlying AI model (e.g. Meta Llama, NVIDIA, or OpenAI-compatible models).
  3. The AI returns an analysis result to Klause AI's server.
  4. The analysis is returned to your browser.
  5. The document text is not retained by Klause AI after Step 4. It is not written to any database or storage system.

Important: On free-tier AI models, some underlying providers may use API inputs to improve their models — this is standard practice for free-tier AI. Pro tier uses commercial models under strict data-processing agreements that prohibit training on your data.

Uploaded files (Pro): PDF and DOCX files are stored temporarily on Vercel Blob storage (encrypted at rest) and automatically deleted within 24 hours.

4. Third-Party Services

5. Legal Basis for Processing (GDPR / UK GDPR)

  • Contract (Art. 6(1)(b)): Processing email, subscription status, and payment records to provide the Service.
  • Legitimate interests (Art. 6(1)(f)): Rate limiting, fraud prevention, security logging, anonymized analytics. LIAs conducted and documented.

  • Legal obligation (Art. 6(1)(c)): Financial records retained 7 years as required by applicable tax law.

6. International Data Transfers

Personal data of EEA/UK residents may be transferred to the US when processed by Vercel, Supabase, Stripe, or OpenRouter. Transfers are safeguarded by:

  • Standard Contractual Clauses (SCCs) approved by the European Commission under GDPR Article 46(2)(c)
  • UK International Data Transfer Agreements (IDTAs) for UK GDPR
  • EU-US Data Privacy Framework adequacy decisions where applicable
