Principles that survive contact with a roadmap
Anyone can publish values. These are the specific rules that decide what ships, written down so you can hold us to them.
We write for intelligent adults
Meia names hormones, cites mechanisms and uses real numbers, because you are capable of reading them and because vagueness is a form of disrespect. Estradiol, progesterone, cortisol, ferritin and thyroid function appear in our interpretations by name when relevant. What you will never read from us: cheerfulness in place of substance, wellness euphemism, or the word "journey" used unironically.
We interpret, we do not alarm
The same data can be presented to inform or to frighten. Ordinary fluctuation is described as ordinary. Uncertainty is labelled as uncertainty. Where something genuinely warrants prompt medical attention, we say so plainly, once, without theatre. Calibration is a moral obligation for anything that speaks about your health.
Patterns over snapshots
Endocrine systems move on timescales of days, months and years. Meia is engineered around repeated observation because that is where the information is. We would rather tell you something true about your last eight weeks than something dramatic about this morning.
The line stays bright
Meia Lab prepares you for clinical care. It does not provide it. No feature ships that diagnoses, prescribes or nudges you away from a professional. We consider this boundary a design asset, not a limitation: it is precisely what lets us be candid everywhere else.
Privacy is architecture, not a page
Health data is special category data under UK law and we treat it as such: encryption by default, collection limited to what interpretation requires, export and deletion built into the product, and no sale of your data to anyone, ever. The business model is a subscription. You are the customer, not the inventory.
We say so when we are wrong
Interpretations carry confidence honestly. The product states what informed a score and what would change it. When we correct something, we correct it visibly.
