Questions, answered.
Is Human Codex medical advice?
No. Human Codex provides decision-support information, not medical advice. Always consult a licensed healthcare professional before changing your diet, exercise, supplementation, or medication.
What do I need to use it?
An iPhone with Apple Health. An Apple Watch makes signals like HRV, resting heart rate, and sleep much richer, but it isn't required. You can also log glucose, ketones, and blood pressure manually.
How does the free trial work?
Start your subscription on the App Store and the first 7 days are free, with full access. Cancel anytime before the trial ends and you won't be charged; otherwise the plan you picked starts automatically.
Is my health data private?
Your data is never sold, it's encrypted in transit, and the app shows no ads. When you use the Agent, it sends our cloud AI providers what it needs to answer. In the app, tracking happens only with your permission, for ad measurement and never with health data. You can delete your data from the app anytime. See our Privacy Policy for the full picture.
Does it work in Spanish?
Yes. Human Codex is fully available in English and Spanish.
Can I cancel anytime?
Yes. Subscriptions are billed through the App Store and you can cancel anytime from your App Store subscription settings. No questions, no friction.
