Important: Differential is an educational simulator. It is not a clinical tool, does not provide medical advice, and must never be used to enter, store, or process real patient-identifiable information (PHI/PII) in cases, chats, or feedback.
1. Information we collect
- Account details: email, display name, year of study.
- Usage data: the cases you attempt, decisions you make in simulations, scores, and progress.
- Optional feedback: messages you submit via the Feedback widget, including browser, OS, screen size, page, and timestamp captured automatically.
- BYOK API keys: if you supply your own Google Gemini API key, it is stored only in your browser's local storage and forwarded per-request to Google. We do not persist it on our servers.
2. How we use it
- To operate, secure, and improve the platform.
- To personalise your curriculum, tutor recommendations, and scoring.
- To respond to support requests and investigate bug reports.
- To monitor aggregate usage (which features are used most, where users get stuck).
3. Cookies & local storage
We use browser local storage for authentication sessions, your BYOK key, and onboarding flags. We do not use third-party advertising cookies.
4. Third-party services
- Authentication & database: Lovable Cloud (Supabase infrastructure).
- Hosting: Cloudflare edge network.
- AI providers: Google Gemini (via your own API key) for AI Simulator, Tutor, and adaptive curriculum.
5. Data security
All traffic is encrypted in transit (TLS). Database access is gated by row-level security policies. You should still avoid entering any real patient data.
6. Your rights
You can view, correct, or delete your account data at any time from Settings. Email us to request a full export or erasure.
7. Children's privacy
Differential is intended for users aged 16 and over. We do not knowingly collect information from children under 16.
8. Changes to this policy
We may update this policy. Material changes will be announced in-app or by email.
