Terms

Last updated November 1, 2026. CycleHelm is run by Maxed Labs Ltd. By using it you agree to these terms.

What CycleHelm is, and isn't

CycleHelm works out estimates from dates you enter, using published methods, and offers general information about cycles and pregnancy. It is not medical advice, a diagnosis or a substitute for a clinician. It is not a method of birth control and must not be used to avoid pregnancy. If you're worried about your health or your pregnancy, contact your clinician or midwife; in an emergency, call 911.

Your account

You need to be 18 or older. Keep your password to yourself. You're responsible for what happens in your account, and for who you share a partner link with. Anyone with the link can see what it shows until you turn it off.

Pro

Pro costs $5.99 a month or $39 a year in US dollars, billed in advance by Stripe, and renews automatically until you cancel. Cancel any time from Settings; you keep Pro until the end of the period you paid for. If we change the price we'll tell you at least 30 days before it applies to you.

Your data

What you log is yours. We use it only to run CycleHelm for you, as the privacy policy describes. You can export or delete it at any time.

Fair use

Don't try to break, overload or get around the limits of the service, or use it to access other people's data.

Our responsibility

We work to keep CycleHelm accurate and available, but estimates can be wrong and services can go down. To the extent the law allows, CycleHelm is provided as it is, and we aren't liable for decisions made on the basis of its estimates. Nothing here limits rights you have under law that can't be limited.

Changes

If we change these terms in a way that matters, we'll email you first. You can always delete your account if you don't agree.
