Nana Technology Charter

Nana uses data to support a woman’s choices, not to define her. A recommendation should create clarity, never take away agency.

No single metric- including cycle phase, weight, HRV or training load – tells the whole story. Nana combines multiple signals and leaves room for the athlete’s own experience.

An individualised answer can still be wrong. We will be clear about uncertainty, limitations and the difference between guidance and medical advice.

When performance goals and health signals pull in different directions, our product should prioritise health and encourage appropriate human support.

We do not treat all women, cycles, contraceptive methods, life stages or sporting backgrounds as interchangeable. We test for blind spots and keep widening the experiences that inform the product.

We use the best relevant evidence available, involve domain experts and revise our approach as knowledge develops. We will not turn early findings into universal rules for the sake of a cleaner headline.

Technology may help generate or adapt guidance, but Nana’s team remains responsible for the systems we build, the safeguards we set and the choices we make.

We collect data with a clear purpose, limit access, protect it appropriately and do not use intimate health information to manipulate or shame athletes.
