This is all because advertisers desperately want to know if you’re pregnant, ideally even before you know it. That way, they can start hitting you hard with ads about baby products, getting product loyalty before competitors. https://t.co/4wKjU1fxNx

Honestly don’t understand why there aren’t more startups creating on-device, non-cloud health trackers. Something that functions better than an Excel sheet but also doesn’t sell your extremely private health data to advertisers. https://t.co/ff2id0g8Ve

Period-tracking apps sent Facebook data about women's contraception, mood and when they'd had sex: https://t.co/KaDuyKn1MA@karen_ec_levy calls it “menstrual surveillance.” Once the data is out there, women have zero control over where it goes https://t.co/9mRXlpTtTk

cool, nothing to see here, just apps that track your periods, symptoms, sexual history, mood, birth control use, & location info being shared with facebook & advertisers. https://t.co/WKj5gOcy2m

— alexandra j. roberts (@lexlanham) September 9, 2019

Uh oh. As feared, period app info is being sold on, in this case to Facebook. What is positioned as a tool for women’s wellbeing becomes a form of gendered mass surveillance. Implications are terrifying. https://t.co/8xoOwwhh6p

I’m not a woman or a person who has a period, but if you do and you track your cycles, SpotOn by @PPFA:
☑️ doesn’t push anti-abortion, anti-contraception propaganda
☑️ never hands users’ health data to advertisers
☑️ is free to use

Just sayin’. https://t.co/Xlyb8rjxNj

A period tracker app asked users to enter information about when they’ve had sex and what kind of contraception they used, and also included a diary-like section for users to write their own notes. It shared all of that data with Facebook. Facebook.https://t.co/ajHTR1u4VI

Third-party health apps that aren't created by or for a HIPAA-covered provider are NOT regulated by HIPAA. Which makes the sensitive health information you put into them fair game for the developers. https://t.co/8BvbkaVvsz
