Privacy Policy for TrackR

Last updated: June 30, 2026

Overview

TrackR ("we", "our", or "the app") is a motorsports data logging application for drag racers. This privacy policy explains what information we collect, how we use it, and your choices.

Information We Collect

Information you provide directly

• Car name, year, make, and model
• Run data (elapsed times, reaction times, dial-ins)
• Setup and configuration data
• Notes about your runs

This information is stored locally on your device only and is never transmitted to our servers.

Camera & Photos

TrackR requests camera and photo-library access solely to scan timeslip photos using optical character recognition (OCR). To read a timeslip, the image is sent to our OCR provider, Anthropic (the Claude API), which extracts the printed data and returns it to the app. The image is used only to perform this scan — it is not retained on our servers and is not used to train AI models. The original photo stays on your device with your run record. See Third-Party Services below.

Anonymous Performance Data (Optional)

With your permission, TrackR collects anonymous run data to improve ET prediction accuracy for all users. This includes:

• Elapsed time and density altitude pairs
• Calculated wind component (not raw speed or direction)
• Engine type category (NA, nitrous, supercharged, or turbocharged)
• Predicted vs. actual ET difference
• Track distance (1/8 or 1/4 mile)
• Weather tier

This data cannot be used to identify you. We do not collect your name, car identity, NHRA/IHRA number, exact location, or any personal information.

You can opt out at any time in Settings → Data & Privacy.

Information We Do NOT Collect

• Your name or contact information (unless you choose to provide it in your profile)
• Stored location history — we never save your location. Your GPS coordinates are sent to our weather provider only to fetch current conditions (see Third-Party Services) and are not stored on our servers
• Opponent information
• Stored copies of your photos — timeslip images are processed transiently for OCR and are not retained by us (see Third-Party Services)
• Any information that could identify you or your vehicle

Third-Party Services

TrackR relies on a few third-party services to provide core features. We share only the minimum data each service needs, and none of them receive your identity.

• Anthropic (Claude API) — when you scan a timeslip, the photo is sent to Anthropic to extract the printed data via OCR. The image is used only to return that data; it is not retained by us and is not used to train AI models. See the Anthropic Privacy Policy.
• Open-Meteo (weather) — your GPS coordinates are sent to Open-Meteo to retrieve current weather and density-altitude conditions for your location. The coordinates are used only for this lookup and are not stored on our servers.
• Amazon Web Services (AWS) — optional anonymous performance telemetry and any feedback you send through the in-app feedback button are stored on secure AWS infrastructure in the United States. Feedback messages do not include your name or email.

How We Use Information

• Anonymous run data is used solely to improve ET prediction accuracy
• No data is sold to third parties
• No data is used for advertising

Data Storage

All personal data is stored locally on your device using SQLite. We do not operate a user account system. Anonymous telemetry data is transmitted to secure AWS infrastructure in the United States.

Children's Privacy

TrackR is not directed at children under 13. We do not knowingly collect information from children.

Changes to This Policy

We may update this policy as the app evolves. Continued use of the app after changes constitutes acceptance of the updated policy.
