Period Tracker Apps: Maya And MIA Fem Are telling Facebook when you last had sex and more

Period tracker apps are sending deeply personal information about women’s health and sexual practices to Facebook, new research has found.

UK-based advocacy group Privacy International, sharing its findings exclusively with BuzzFeed News, discovered period-tracking apps including MIA Fem and Maya sent women’s use of contraception, the timings of their monthly periods, symptoms like swelling and cramps, and more, directly to Facebook.

Women use such apps for a range of purposes, from tracking their period cycles to maximizing their chances of conceiving a child. On the Google Play store, Maya, owned by India-based Plackal Tech, has more than 5 million downloads. Period Tracker MIA Fem: Ovulation Calculator, owned by Cyprus-based Mobapp Development Limited, says it has more than 2 million users around the world. They are also available on the App Store.

The data sharing with Facebook happens via Facebook’s Software Development Kit (SDK), which helps app developers incorporate particular features and collect user data so Facebook can show them targeted ads, among other functions. When a user puts personal information into an app, that information may also be sent by the SDK to Facebook.

Asked about the report, Facebook told BuzzFeed News it had gotten in touch with the apps Privacy International identified to discuss possible violations of its terms of service, including sending prohibited types of sensitive information.

Maya informs Facebook whenever you open the app and starts sharing some data with Facebook even before the user agrees to the app’s privacy policy, Privacy International found.

“When Maya asks you to enter how you feel and offers suggestions of symptoms you might have — suggestions like blood pressure, swelling or acne — one would hope this data would be treated with extra care,” the report said. “But no, that information is shared with Facebook.”

The app also shares data users enter about their use of contraception, the analysis found, as well as their moods. It also asks users to enter information about when they’ve had sex and what kind of contraception they used, and also includes a diarylike section for users to write their own notes. That information is also shared with Facebook.
