Clarity through every phase

FAQ

Who is eligible for this offer?

This offer is available to eligible customers who purchase WHOOP and are new to Natural Cycles. Terms and eligibility requirements apply.

How do I claim my free year of Natural Cycles?

After purchasing WHOOP, you'll need to receive and set up your WHOOP before claiming your free year of Natural Cycles. Once your WHOOP is set up, you'll be prompted in the WHOOP app to start the Natural Cycles integration and redeem your offer.

How do WHOOP and Natural Cycles work together?

WHOOP passively collects your skin temperature while you sleep. Once you connect WHOOP to Natural Cycles, WHOOP shares your temperature data with Natural Cycles each day. Natural Cycles then uses its own algorithm to deliver your daily fertility status in the Natural Cycles app.

What information does WHOOP share with Natural Cycles?

With your permission, WHOOP shares skin temperature data with Natural Cycles. WHOOP does not share your full WHOOP data with Natural Cycles, and your daily fertility status is provided in the Natural Cycles app, not in the WHOOP app.
