Privacy Policy

October 4, 2026

SpeedReflex is built on a simple foundation: we do not want, collect, or monetize your personal data. All calculations happen directly on your device inside your web browser.

1. Geolocation & GPS Speed Data

When using our GPS speedometers, geolocation is requested only upon tapping Start. Position coordinates and Doppler speeds are processed solely in client-side RAM and are never transmitted to any server.

2. Browser Local Storage

We use localStorage strictly for user preferences (speed units, theme) and personal session history. You can clear this data at any time via Clear History or your browser settings.

3. Cookies & Tracking Technologies

SpeedReflex does not set tracking cookies, marketing cookies, or fingerprinting scripts. Fonts are self-hosted.

4. Hosting & Ephemeral Technical Logs

Hosting providers record routine HTTP connection logs for security and routing. These are purged on rolling schedules and never tied to personal profiles.

5. Sharing Challenge Links

Challenge links encode only the numerical score in URL parameters, without your name, identity, or location.

6. Your Rights (GDPR & CCPA)

Because we store zero personal data on remote servers, your data is already exclusively under your local control.
