Nidela
Your cycle stays on your phone. Nowhere else.
Nidela is local-only period tracking. You log what matters — dates, flow, symptoms, notes — and it never leaves your device. There is no account, no cloud sync we operate, no analytics, and no advertising.
Health data is sensitive enough that the architecture should make the promise true, not just written down. We cannot see your logs because we never receive them.
