Data We Collect
OncoToolkit is designed with privacy in mind. We collect minimal data to provide and improve our services:
Automatically Collected Data
- Usage Analytics: We use Google Analytics (measurement ID: G-RE1E219ZC0) to collect anonymized usage data such as pages visited, session duration, device type, browser type, and general geographic location (country/region level). This data is aggregated and does not personally identify you.
Data You Provide
- Calculator Inputs & Saved Results: Any clinical data you enter into our calculators is processed and stored entirely within your own browser using
localStorage. No patient data or clinical inputs are ever transmitted to or retained on our servers. - Contact Information: If you contact us via email, we will collect your email address and the content of your message for the purpose of responding to your inquiry.
Data We Do NOT Collect
- We do not collect any Protected Health Information (PHI).
- We do not require user accounts or login credentials.
- We do not collect names, addresses, phone numbers, or financial information.
- We do not sell or share personal data with third parties for marketing purposes.
How We Use Your Data

Service Improvement: To understand how our tools are used and to improve calculator accuracy, usability, and content relevance.
