About Preact Health

Our Mission

We believe healthcare should be clear, not confusing. At Preact Health, we’re building tools that help you understand your health as easily as you understand your credit score.

No jargon. No judgment. Just clarity.

The Problem

Healthcare is broken in many ways, but one fundamental issue is communication:

  • Medical terminology that excludes patients from their own care
  • Insurance explanations that might as well be in a foreign language
  • Fragmented information across multiple providers
  • No single, standardized way to understand your overall health status

Your health should be something you understand, not something that happens to you.

Our Solution

Preact Health provides a comprehensive health scoring system that:

  1. Quantifies Health — Converts complex medical data into a single, understandable score
  2. Explains Clearly — Shows exactly how different factors contribute to your score
  3. Tracks Progress — Monitors changes over time so you can see improvement
  4. Empowers Decisions — Gives you the information you need to take charge of your health

The Science

Our scoring system is built on:

  • Evidence-Based Medicine — Risk factors validated by clinical research
  • Transparent Algorithms — Open source code that anyone can review
  • Continuous Validation — Regular audits comparing our scores to clinical outcomes
  • Peer Review — Input from healthcare professionals and data scientists

All our methodology is documented and available on our Documentation pages.

Open Source

We believe in transparency. Our core algorithms are open source and available on GitHub.

Why? Because:

  • Trust — You can see exactly how your score is calculated
  • Validation — The medical and scientific community can verify our methods
  • Improvement — Contributions from experts make the system better for everyone
  • Reproducibility — Other researchers can build on our work
  • Collaboration - We want thsi to be your product and need your input

Privacy & Security

Your health data is deeply personal. We take its protection seriously:

  • Encryption — All data encrypted in transit and at rest
  • GDPR Compliant — Full compliance with European data protection standards
  • No Selling — We never sell your personal or health information
  • Data Minimization — We only collect what’s necessary for scoring
  • Your Control — You can export or delete your data anytime
  • Transparency — Clear, accessible privacy policy in plain language
