According to a recent study by Privacy International based in the UK, it has been observed that many menstrual tracker apps share the most critical data about the user to third party services. They share data like a monthly period cycle, sexual encounters if any, and also contraception use of medications if any. Apps like Maya and MIA Fem have reportedly shared the data of its users to third-party like Facebook through its Software Development Kit (SDK).
Through this research, it is said that social media giant SDK helps apps like Facebook to include particular features and also show ads depending upon the user data. It is said that when the user of the app registers its information in the app, that information is also sent to Facebook through its SDK software. Maya, which is a period tracking app, shares the data of its user even before the user agrees for its privacy policies so that it can help them strategically to put ads which the user may be most likely to buy. Also, it has been observed that women those who are likely to get pregnant or are pregnant are more likely to change their shopping habits. The app also enters its user’s data like mood swings to help them advertise accordingly. Maya’s parent company Plackal Tech told that displaying ads like these on a platform like Facebook helps them earn revenue, and if the users do not wish to see these ads, it can opt-out by taking its premium subscription. Not only these two apps were found, but it was also observed that apps like My Period Tracker, Ovulation Calculator, and Mi Calendario notifies apps like Facebook after the user starts using this app. Also from the study it has been seen that popular apps like period tracker by Leap Fitness Group, Period tracker Flo by Flo Health do not share any information about its users to Facebook.
These apps are not new, and can surely help you in your menstrual cycle and also in your ovulation cycle. Recently Apple and Fit Bands have incorporated these menstrual apps in their devices.
