  • Privacy. Anonymous by design: your responses to the questionnaire stay on your device for the survey experience; anonymous aggregate increments are sent to FourD so the collective chorus stays accurate—we do not keep a personal response record. If you email yourself a report, images pass through our mail server only for that send—they aren’t kept as a profile, and your email isn’t linked to your responses. Delivery logs keep only a masked fingerprint of the address (not the address itself) and are deleted after 30 days.
  • Data Value Charter · FourData For You. Data for you, not from you — personal and health data should create value for you first; FourD doesn’t sell or profile you from survey answers.

FOURDTotal

The Total Health Platform

FourDTotalVirtual FourDyad and real FourDyno connected by FirstYOU, Your health. Crisp vector artwork.

Two worlds. One Human Bridge.

FOURDTotal is FourD’s proprietary platform for pursuing Total Health—reconnecting everything that matters: the whole person, relevant health data and context, how the parts interact, and how the whole changes over time.

Its three-part framework brings together FOURDyad, the virtual-world Health Intelligence Engine; FOURDyno, the real-world Holistic Health Flywheel; and FirstYOU, the Human Bridge connecting them through the individual.

Two worlds. One human bridge. One FOURDTotal approach.

FOURDTotal reconnects the computational world of data and intelligence with the lived world of biology, behavior, environment, choices, and outcomes—while keeping agency with the individual.

FOURDyad

The Health Intelligence Engine

Where advances in HealthTech — health data, science, sensing — and CompuTech — computation models — are hybridized so fragmented signals can be interpreted together and in context.

  • Health data + context — clinical, vision, dental, self-tracked
  • HealthTech evidence — trials, studies, science
  • Computational intelligence — AI, data, modeling
  • VisionAI — visualization and digital representation
  • HealthAI — personalized, predictive, actionable intelligence

Purpose: reconnect fragmented data into usable health intelligence.

FOURDyno

The Holistic Health Flywheel

The real world: where Nature, Nurture, Detection, and Decision continuously interact to shape Outcomes over time.

  • Nature — biology, genetics, intrinsic factors
  • Nurture — environment, behavior, relationships, context
  • Detection — what can be observed, measured, inferred
  • Decision — what people and the ecosystem choose to do
  • Outcomes — what changes in the real world

Purpose: reconnect innovation, decisions, and lived outcomes in a continuous learning dynamic.

FirstYOU

The human bridge is you.

Intelligence becomes meaningful only when it helps a person understand, decide, act, and learn.

FirstYOU reconnects the individual with health intelligence, real-world decisions, and the value created by personal data. FourD helps organize, interpret, visualize, and support the journey—but the center of gravity remains with the individual.

FOURD helps. You own.

Your health, your decisions, your data, your trajectory.
