That's fine! But our app is more than a period tracking app. If you have a menstrual cycle the period tracker is there for you to know when to do your self-exam as well (3 days after your period). We'd also like for you to be aware that it's possible the period tracking app you are using is collecting and selling your personal health data, and our app will not do that. To learn more about period apps collecting your personal health data click here.

Nope! You can opt into our monthly newsletters by entering in your email when you first download the app, but it is optional and does not cost any money.

On the home screen (period dial screen) on the app you will notice a little gear in a circle to the bottom left of the period dial. Click the gear and you are now able to edit the length of your period by pressing the "+" and "-" symbols above the pink section to add and subtract days from your period. You can also edit which day you are on in your cycle by moving the lemon around the circle. You can edit your cycle's length at the bottom of the screen. Lastly, if you don't have a period you can toggle the option below "period" to the bottom right of the cycle to take out the period option on the app. The app will then remind you on the first of each month when to do your self-exam rather than 3 days after your period.

While this is the Tyrer-Cuzick risk assessment used by physicians, an official risk assessment should be performed by your doctor in order to record your risk for your health record. This app is a tool to help you understand different risk factors, and creates a list of risk factors to discuss with your doctor as part of determining a screening plan. Everything with the app is meant to help you better communicate with your doctor and to provide education to support those conversations. It is not to replace those important conversations.

The information you enter on the app, stays secure in your account. You can delete your account in the app at any time. All data, badges earned, and your screening plan will be deleted with it and is not recoverable.
