While we realize there are a slew of “free” period tracking apps available, it’s important to note that Natural Cycles is so much more than a period tracking app - and all of the reasons we are different add up to why we need to charge a subscription fee.
First things first, our subscription helps protect you and your data. Natural Cycles has always taken data privacy seriously and has very strict protocols in place to protect your data. We have never — and never will — sell users’ data because we don't need to make money elsewhere.
Second, as a regulated birth control method, the subscription fee enables us to conduct the necessary scientific research required by regulatory bodies (such as the FDA), as well as other important activities to make sure we are offering our users the best product we can.
In addition to our regulatory processes, our Medical Science Team is constantly carrying out research to further the field of women’s health and we've published many peer-reviewed studies and research. You can find more information about this here.
If you’re located in the United States, the Annual subscription to Natural Cycles should be covered by private insurance plans, and we are available for FSA/HSA reimbursement.
