2. Health Data Processing (Client-Side & Storage)

When you enter your age, sex, height, weight, blood pressure, or body measurements into our calculators:

• Client-Side Computation: Calculations occur in real-time inside your browser. Your raw physiological entries are not transmitted to any tracking servers for ad profiling.
• Local Storage: When you click "Save Result", your records are stored solely in your browser's private `localStorage`. You can delete individual records or clear your entire history at any time from the Dashboard.
• Firebase Authentication & Cloud Storage: If you voluntarily choose to sign in with Google or create an account, your profile and saved logs are synced with Google Cloud Firestore over TLS 1.3 encryption. You retain the right to delete your account and all associated cloud data at any time.

3. Cookies, Web Beacons & Google AdSense

We use cookies and similar technologies to enhance user experience, remember theme preferences (dark/light mode), and serve contextual advertisements via Google AdSense.

4. Google Analytics (GA4) Disclosures

We use Google Analytics 4 (GA4) to understand aggregate website usage (such as page views, popular calculators, bounce rates, and browser types). GA4 processes anonymized IP addresses and does not store personally identifiable medical data.
