Help keep this tool free, private, and available without an account.

When Did It Start? is an independent public-interest project created by Nick Madison.

What support makes possible

Voluntary contributions can help cover hosting, accessibility testing, independent clinical review, future language translation, research development, and continued maintenance of the public resource links.

Donation link coming soon

The public tool will remain available without a required payment. A verified support link can be added here before launch.

Support the project

No payment wall while someone is sick

The symptom-record flow should never be interrupted by a donation prompt. Support belongs here, in the footer, and after a record is complete—not between the user and the tool.
