Nia — Period & Cycle Tracker

Nia tracks your cycle without tracking you.

Most period apps send your health data to their servers. Nia doesn't. Everything you record stays on your phone. No account, no email, no phone number. We cannot see your data, and neither can advertisers.

WHAT'S INSIDE
- Cycle calendar with period, ovulation and fertile window predictions
- Symptom log: mood, pain, discharge, sleep, energy, basal temperature
- Your complete cycle history, with no time limits
- Doctor's report as PDF or CSV, created on your phone
- Cycle insights: average length, patterns and trends

BUILT FOR IRREGULAR CYCLES
Most apps average your cycles, so one unusual month ruins predictions for months. Nia uses a weighted median, and you can mark any cycle as atypical so it stops skewing your predictions. If your cycle varies, Nia shows a range instead of pretending to know an exact date.

PRIVACY BY DESIGN
- No account, no sign-up
- No ads, no advertising identifiers, no tracking
- Your health data is never sold or shared
- Delete everything with one button, instantly
