Privacy Policy
Last updated: April 2026
Minimal Data Principle
As a clinician-led project, OpiCalc is built on the principle of Zero Data Retention. We do not store, track, or sell patient data or clinician usage patterns. Calculations are performed locally on your device and are cleared as soon as the session ends.
No Accounts
You do not need to register or log in to use our clinical tools. This ensures your professional identity remains anonymous.
No Tracking
We do not use invasive tracking pixels or third-party behavioral analytics that compromise clinical confidentiality.
Information We Collect
We only collect anonymized, high-level traffic data (e.g., page views) to understand which clinical tools are most needed. This data contains no personally identifiable information (PII) or clinical inputs.
