PERSONAL MEANS PERSONAL

Your rhythm
stays yours.

You choose what to connect
and what to share.

Apple Health is optional. Health-based observations and work history are processed and stored on your iPhone. Usage analytics starts only if you choose to share it.

Read the Privacy Policy

Cycle dates and fatigue outlooks are estimates. They don’t tell you how you will feel. Cyrena supports planning and does not provide medical advice.

A FEW THINGS TO KNOW

Before you
begin.

Can I try Cyrena now?

The iPhone beta is coming soon. Public access is not available yet. This page will be updated when joining is possible.

Will the beta be free?

All features will be free during beta testing. Free access applies to the beta testing period.

Which calendars can I connect?

Cyrena supports Apple Calendar and Google Calendar. You choose which calendars to display and which writable calendar to use for new events or focus sessions.

Do I have to connect Apple Health?

No. Health features are optional. You decide which permissions to grant. Cycle and fatigue estimates depend on the history available to the app.

Does Cyrena change my plans automatically?

You review suggested changes and choose what to apply. Connecting a calendar does not give Cyrena permission to rearrange your day without that choice.

YOUR DAY, WITH A LITTLE MORE ROOM.

A little more
you.

Your schedule, check-ins and focused work.
Together in Cyrena.
