Privacy Policy

1. Commitment to Biometric Data Privacy

At ZenFit Tools (accessible via our official domains, contact: zenfittools@gmail.com), visitor privacy is our highest priority. This Privacy Policy documents how personal data is handled in full compliance with the European Union General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and international privacy frameworks.

2. Browser-Based Calculator Processing

All 19 calculators provided on ZenFit Tools (including body weight, circumferences, body fat percentages, maximal heart rates, one-rep maxes, running paces, and fasting timers) execute entirely within your local browser runtime via JavaScript.

Calculator inputs are processed locally in your browser. Contact-form submissions are handled by EmailJS as described in our Privacy Policy. Your physiological inputs, personal biometric metrics, and daily calculations are processed locally on your device.

3. Google AdSense & Third-Party Advertising Compliance

We may partner with Google AdSense and certified advertising exchanges to display discrete, non-intrusive advertisements. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve relevant ads based on visits across the internet.

Users may opt out of personalized interest-based advertising at any time by visiting Google Ad Settings (https://www.google.com/settings/ads) or aboutads.info.

4. Direct Communication & Inquiries

When contacting us directly via zenfittools@gmail.com or our contact portal (powered by EmailJS client transmission), we only process the sender name, email address, and message content for the explicit purpose of responding to your inquiry or feedback. We never sell, lease, or distribute your email address to commercial marketing firms or third parties.
