Before you begin — a quick note

  • ✦ This app is for education and personal organization — it is not a medical record and does not replace your oncology team.
  • ✦ Do not enter full names, phone numbers, addresses, or other identifying details in free-text fields.
  • ✦ Personal health details you enter are stored only on this device. Clearing browser storage removes them.
  • ✦ Analytics are collected in aggregate only — no patient health details are tracked.
  • ✦ Always consult your oncology team about symptoms, treatment decisions, and urgent concerns.
  • ✦ This program is supported by an independent educational grant. The supporter does not control the content and never receives your information.
