Helena is a cat. She doesn't care about your data. We follow her lead and ensure all your data remains offline and on your device. You want to delete it? It's gone. You want to export it and do something else with it? Go ahead.

We don't retain, sell, or train on your data. It's always yours.

Periods suck. We want to make tracking them as seamless as possible.

Want to track headaches by severity? Type of flow? Mark a cycle as irregular? Do it!

The app is meant to support you, not force you into what someone thinks is important.

HelenaCat is a free app. Full stop.

Features will never be blocked by paywalls. There won't be a new and improved version, or a free/paid app.
