/* TEAM */ Developer & maintainer: Prom Parndejpong Site: https://rct.fyi /* METHODOLOGY */ n-of-1 randomized controlled trials. The rigor is the product. The statistical engine is public, pure and fully tested — read it, don't trust it: https://github.com/promptplearn/rct-engine. Block-level sign-flip permutation test, reproducible seeded allocation, preregistration sealed with a canonical-JSON SHA-256. /* COLOPHON */ Stack: Vite, React, TypeScript, Tailwind. Local-first: IndexedDB. No accounts, no server, no tracking. Open where it counts: the engine that computes your result is open source; the app shell around it is closed. The math is the part that has to be right. License: AGPL-3.0-or-later. Last updated: 2026-05-30 /* THANKS */ To everyone who runs their own trial instead of taking it on faith. iykyk.
