Privacy & Data

Your Privacy & Data Rights

CardioAge is designed with privacy at its core. Here is exactly how your data is handled.

Core Privacy Principles

Local-only storage: All your health data is stored exclusively in your browser's localStorage. It never leaves your device.
No data transmission: No health values (blood pressure, cholesterol, etc.) are transmitted to any server, ever.
No advertising use: Your health data is never used for advertising, profiling, or any commercial purpose.
No data sale: CardioAge does not sell, share, or license your personal health data to any third party.
Full data portability: You can export all your data at any time in machine-readable JSON format.
Right to deletion: You can permanently delete all your data from this device at any time.

Technical Architecture

All risk calculations are performed client-side in your browser using JavaScript. No health data is sent to a server for processing.

Data storage: Risk snapshots and profile information are stored in your browser's localStorage. This data persists until you clear your browser data or use the deletion function below.

Analytics: This application may collect anonymised, aggregated usage statistics (e.g., which risk model was selected, page views) via a privacy-respecting analytics service. No raw health values are included in any analytics data.
