Terms & Disclaimer
A quick, honest note on what WifeLine is — and what it isn't. You agree to these when you first open the app.
It's a tracker, not a doctor
WifeLine helps you track and understand cycles, moods, and pregnancy. It is not a medical device and does not provide medical advice. For anything health-related, please talk to a qualified healthcare professional.
Predictions can be wrong
Fertile windows, period dates, and phase estimates are calculated from the information you enter. Cycles vary from person to person and month to month, so these predictions are estimates and may be inaccurate.
Not birth control
WifeLine is not a form of contraception and should never be relied on to prevent — or to guarantee — pregnancy. Fertility awareness has a real failure rate, and pregnancy is possible even on days the app marks as lower chance. Please use a proven contraceptive method if you are avoiding pregnancy.
Your decisions are your own
Any decision you make using WifeLine — about intimacy, contraception, conception, or your health — is your own. To the fullest extent permitted by law, we are not liable for pregnancy, for missed or inaccurate predictions, or for any outcome resulting from use of the app. The app is provided “as is,” without warranties of any kind.
Your data
Your entries are stored to provide the app and are shared only with a partner you choose to link. By continuing, you agree to this use of your information. The privacy policy has the details.
