Privacy Policy

Last Updated: November 2025

Privacy-First Approach

PaceCalc Pro is designed with your privacy as a top priority. We do not collect, store, or transmit any personal data to our servers.

All calculations, settings, and history are stored locally in your browser using IndexedDB and localStorage. Your data never leaves your device.

What We Don't Collect

  • Personal identification information (name, email, phone number)
  • Calculation inputs or results
  • Training data or fitness information
  • Race times or performance metrics
  • Location data
  • Device-specific identifiers

Local Storage

PaceCalc Pro uses browser-based storage (IndexedDB and localStorage) to:

  • Save your calculation history for quick reference
  • Remember your unit preferences (miles vs kilometers)
  • Store your VDOT progression over time

This data is stored entirely on your device. You can clear it at any time through your browser settings or using the "Clear History" buttons within the app.

  • Does not use cookies
