Getting started
What is PMDD, and is Prova a diagnosis?
PMDD (premenstrual dysphoric disorder) is a cyclical, hormone-driven mood disorder. Prova is a tracking tool, not a diagnosis. It documents your symptom pattern so a qualified clinician can make the call. Every report says exactly that.
How long until I see a pattern?
A trustworthy read needs a couple of weeks of daily logs — ideally across two cycles. Your proof-curve starts filling in from day one, and the pattern verdict unlocks once there's enough data.
What if my cycle is irregular?
You set your typical cycle length at setup, and Prova refines it once you've logged two periods. Prediction degrades gracefully — it never pretends to be certain when your cycle isn't.
Your data
Is my data private?
Yes. Everything stays on your device — no account, no cloud, no third-party analytics on your symptoms. See our Privacy Policy.
Can I export or erase everything?
Pro members can export a clinician-ready PDF from the Pattern screen. Anyone can erase all data permanently from Settings → Erase all data.
