Privacy Policy
Last updated: January 4, 2026
The Short Version
Your privacy matters. All calculations happen in your browser. We don't collect, store, or sell your personal calculation data. Period.
Information We Collect
What We DON'T Collect
- Your calculation inputs or results
- Personal financial information
- Health or medical data
- Names, emails, or contact information (unless you contact us)
What We May Collect
- Analytics data: Anonymous usage statistics like page views, popular calculators, and general traffic patterns (via Google Analytics or similar)
- Device information: Browser type, screen size, and operating system for improving compatibility
- Cookies: Small files to remember your preferences (like recent calculations stored locally in your browser)
How Your Data is Processed
All calculator computations happen entirely in your web browser. Your inputs are never sent to our servers. When you use a mortgage calculator, BMI calculator, or any other tool, the calculations are performed locally on your device using JavaScript.
The "Recent Calculations" feature stores your history in your browser's local storage. This data never leaves your device and can be cleared at any time through your browser settings.

- Google Analytics: To understand how visitors use our site (anonymized)

These services have their own privacy policies. We encourage you to review them.
Cookies
We use cookies for:
- Remembering your preferences
