Privacy Policy & Data Safety
Effective Date: November 10, 2026 • Application ID: app.alarp.mobile
1. Scope and Core Commitment
ALARP (As Low As Reasonably Practicable) is an educational training simulator developed for Radiologic Technology students, clinical instructors, and radiographers.
ALARP DOES NOT COLLECT, TRANSMIT, STORE, OR PROCESS PROTECTED HEALTH INFORMATION (PHI) OR REAL PATIENT RECORDS. All radiographs and positioning diagrams used in the application are anonymized educational reference materials.
2. Information We Collect
ALARP is built on guest-first principles. You can access 100% of the educational curriculum, positioning lessons, and practice simulations without creating an account or supplying personal identifiers.
When you voluntarily create an account to synchronize progress across devices, we collect:
- Account Credentials: Email address and optional learner display name.
- Simulated Practice Telemetry: Collimation accuracy percentages (IoU), central ray offsets (mm), and challenge scores.
- Crash Reporting: Anonymized diagnostic stack traces to identify software defects.
3. Data Retention & Third Parties
Your data is encrypted in transit via HTTPS/TLS and at rest using PostgreSQL on Supabase. We do not sell, rent, monetize, or disclose your personal data to advertising networks or data brokers.
Telemetry and authentication data are processed exclusively by:
- Supabase Inc.: Cloud database and authentication hosting.
- Cloudflare Inc.: Web demo hosting and CDN infrastructure.
4. Account and Data Deletion Portal
Google Play Store Data Safety Compliance Requirement
In compliance with Google Play Developer Policies, all registered ALARP users have the right to request immediate and permanent deletion of their account and all associated telemetry data without retaining the mobile app installed.
Submitting this request permanently purges:
- Your authentication account and email record in auth.users
- Your learner profile, display name, and avatar settings in public.profiles
- Your cumulative collimation practice logs in public.practice_attempts
- Your timed challenge submissions and daily rankings in public.challenge_history
