Your answers stay on your device

What you enter is saved in your browser’s local storage, on the device you are using. It is not sent to us, and there is no account, no login, and no server-side record of your health information. Using a different browser or device means starting fresh. Clearing your browser data deletes it, and so does the delete button in Settings.

What leaves your device, and when

Only when you press the search button on the trials page. At that point NuDavid sends your cancer site, state, travel preference, age group, and biomarker status to our server, which turns them into a search against the ClinicalTrials.gov public API. Your answers are not written to any database or log along the way. No name, contact detail, date of birth, or free text is collected anywhere on this site, because there is nowhere to type any.

No tracking

There are no analytics scripts, advertising pixels, or tracking cookies. Our host records ordinary technical information such as IP addresses and request paths, as any web server does. Health information never appears in a URL.

Links out

Opening a source leaves NuDavid, and those sites have their own policies. Links are sent with no referrer. Trial records are filed by their sponsors, so verify contacts and enrollment status with the study team.

The limits of the medical content

The educational summaries are drawn from National Cancer Institute patient material and have not completed independent clinical review. NuDavid does not give individualized treatment recommendations, drug doses, survival estimates, safe-waiting windows, urgency scores, or eligibility decisions. It makes no claim of HIPAA compliance, FDA clearance, or medical device status, because none apply to it.

Emergencies

NuDavid does not monitor symptoms and cannot help in an emergency. In the US call 911, or your local emergency number elsewhere. For symptoms that are new or getting worse but not an emergency, use the instructions your oncology team gave you, which usually means a direct line rather than waiting for your next appointment.

Before any of this changes

Accounts, record uploads, or server-side storage of health information would require clinical governance, a regulatory assessment, consent and retention policies, a security review, and the relevant agreements. None of that is in place, which is why none of those features exist yet.
