Privacy Policy

Last updated: January 2026

Zero-Trust Architecture

SecureThink is built on a zero-trust data model. The application processes all documents entirely on your local machine using on-device AI models. No document content, queries, or AI responses are ever transmitted to SecureThink's servers or any third-party service.

  • Local processing only — no data exfiltration
  • Model isolation — AI models run entirely on your hardware
  • Air-gap capable — fully functional without internet access after activation

Data We Collect

We collect minimal data necessary to operate the service:

  • Identity data: Name and email address provided at purchase
  • Transaction data: Order details processed by Lemon Squeezy (our payment processor)
  • License data: License key validation to confirm your subscription status
  • Optional crash reports: Anonymous diagnostic data if you opt in

We do not collect: document content, AI queries, outputs, file names, or any other data processed by the SecureThink application.

How We Use Your Data

  • Order fulfilment and licence delivery
  • Licence enforcement and subscription management
  • Customer support
  • Legal compliance

Third Parties

Lemon Squeezy is our sole payment processor. They handle all transactions, taxes, and refunds. We do not share your data with any other third parties for marketing or analytics purposes.

Data Retention

Account and transaction data is retained for 6 years for legal and tax compliance. Document data is retained for zero seconds — it never reaches our servers.

Your Rights (UK GDPR)

You have the right to:

  • Access the personal data we hold about you
  • Rectify inaccurate personal data
  • Request erasure of your personal data
  • Object to or restrict processing
  • Data portability

To exercise these rights, contact us at support@securethink.co.uk.

AI Disclaimer

SecureThink uses large language models (LLMs) that may produce inaccurate, incomplete, or misleading outputs. All AI-generated content should be verified by a qualified professional before being relied upon. SecureThink is not responsible for decisions made based on AI outputs.

Governing Law

This Privacy Policy is governed by the laws of England and Wales.
