About us

About Period Tracker and Calendar

A private, simple way to understand your cycle — made by a team that builds useful everyday apps.

Period Tracker and Calendar helps you log your periods, symptoms and moods, see predictions for your next period and fertile window, and notice the patterns that are typical for you.

Who we are

The app is published by SimpleInnovation (AppManage Group #1, LLC), part of the Digitalchemy family of apps.

What we care about

  • Privacy: your cycle data is personal. Read how we handle it in our Privacy Policy.
  • Clarity: plain language and honest predictions — the app is a wellness tool, not a medical device. See our Medical Disclaimer.
