Your flow, their ad show
Period tracking app has been yapping about your flow to Meta
13M users rage as 'keep a diary' crowd clashes with 'you're the product' chorus
TLDR: A jury found period app Flo liable for sharing sensitive cycle data with advertisers, igniting fury and fear in a post-Dobbs world. Commenters clash between “paper diary or bust,” “use local open-source apps,” and the meme-y “if it’s free you’re the product”—with a twist: users say they paid and still got tracked.
The internet is in full meltdown over claims that period app Flo secretly piped intimate cycle data to ad giants like Meta while promising privacy—leading to a class action with 13 million users and a courtroom smackdown. The community’s verdict? Outrage with a side of memes. One camp is yelling “don’t app your body”, with philipallstar urging people to just keep a paper diary. Another faction is pushing open-source, local-only trackers—no cloud, no creepy surprises. And then there’s the evergreen cynic chorus: “if it’s free, you’re the product.”
Except… it wasn’t always free. Commenters gleefully pointed out Flo’s €10/month premium, turning the thread into a roast: users paid money and still got tracked? That “they had to make money” defense got shredded, with sdoering quipping it’s “not a moral blank check.” The scandal also threw gasoline on bigger fears: post-Dobbs (the Supreme Court decision reshaping abortion rights), people say reproductive data is not just personal—it can be dangerous. Meanwhile, HIPAA (the U.S. health privacy law) doesn’t cover most consumer apps, which the crowd calls a giant loophole.
Between jokes about emoji calendars and “Zuck knowing your cramps,” the vibe is clear: users feel betrayed, regulators look late, and the top comment energy is simple—build less creepy tech or we’re going back to notebooks and air-gapped apps like it’s 1999. Flo hasn’t heard the end of this
