Screwworm Tracker — Privacy Policy

Last updated: April 18, 2026 (rev 3)

Overview

Screwworm Tracker is a free mobile app that helps ranchers, veterinarians, and wildlife professionals report suspected New World Screwworm cases to state veterinary authorities.

Data We Collect

You provide: Email, display name, optional professional details (vet license, organization), observation photos, text descriptions, self-assessment responses, and contact information for FAD reports.

Automatic: GPS coordinates during report creation (not in the background), device model/OS for compatibility, and anonymous crash reports via Sentry.

How We Use Your Data

• Route observation reports to the appropriate state veterinarian's office
• Enable expert review of submitted photos
• Display aggregated observations on a map (personal identity not shown)
• Send you email and push notifications about the status of your submitted observations, including expert-review outcomes (e.g. "confirmed screwworm", "likely not screwworm")
• Send you email notifications about account-security events, such as repeated failed sign-in attempts on your account
• Improve app reliability with anonymized usage data

Data Sharing

• Suspect reports are emailed to the relevant state vet office (the app's purpose)
• State vets may forward reports to USDA APHIS per standard FAD procedures
• We do not sell data to third parties or share with advertisers

Security

Data is stored on US-based servers (Fly.io), photos in encrypted storage, all transmissions over HTTPS/TLS, passwords hashed with bcrypt.

Your Rights

Account deletion: delete your account at any time via Settings → Delete Account in the app, or by submitting the form at screwwormtracker.com/delete-account. Accounts are soft-deleted with a 30-day recovery window; after 30 days your personal information is permanently anonymized.

Data export: download a copy of your data via Settings → Download My Data in the app.

You may use the app as a guest, but suspect-case reports require contact information for veterinary follow-up. For other privacy questions, contact support@screwwormtracker.com.

Camera & Location

Camera access: only when you actively photograph wounds. Location: only during report creation, not continuously. You may manually place a pin instead.

Children

Not directed at children under 13.
