See our full Delete your account page for step-by-step instructions, the data we remove, and what is kept for legal or tax reasons.

Quick version — in the app: More → Profile → Delete Account. This deletes your account and all associated check‑in data within 30 days. You can also email support@RadiantRTapp.com from the address on the account.

If you tapped the wrong score, just log an updated check-in the next day — the graph will reflect the new value. If something feels medically wrong or worrying, contact your care team, not us.

Try these in order: (1) restart the app; (2) make sure the email or Apple/Google account is the same one you used to sign up; (3) use "Forgot password" if you used email sign‑up. If none of that works, email support@RadiantRTapp.com with your device model and OS version.

Only what's needed to run the app: your account email, the symptom entries you add, and basic usage/diagnostic information. We never sell your data. See the Privacy Policy for the full list.

Anyone undergoing external‑beam radiation therapy (breast, head/neck, prostate, lung, pelvic, CNS/brain, or other). Spouses, partners, and caregivers use it too.

Not directly. Trends are designed for you to show in person during your visits. We are not integrated with any hospital EHR. Your data is only yours.
