The developers trying to engineer your love life are as likely to fall victim to privacy missteps as platforms like Facebook or Google.

Why it matters: Dating apps and sites are party to some of our most intimate communications.

Details: Dating apps and sites collect a significant amount of consumer data — and where there is data, there are privacy breaches.

  • An Axios investigation a year ago found that trackers were common on many online dating websites, including from third-party companies.
  • In April, Grindr said it would stop sharing users’ HIV statuses with third-party vendors.
  • Tinder was one of the many outside applications implicated in a data leak that exposed Facebook accounts, since some people who use the dating app use the social giant’s login tool. The dating app said it had found no evidence its accounts were accessed.
  • The gay dating app Jack'd recently experienced a privacy breach that exposed users' photos that were supposedly private.

What they’re saying: Privacy issues in online dating can go beyond accidental breaches or disclosure. The information users provide these platforms can also be used to harass them or as "revenge porn," where intimate images of someone are shared without their consent.

  • “We disclose a significant amount of personal information on these platforms because we have to,” said New York Law School professor Ari Ezra Waldman. “But at the same time, the law does not protect our disclosure when someone wishes us harm.”
  • Privacy concerns can be particularly acute for members of marginalized groups that are more likely to use dating apps or face discrimination and harassment on the platforms.

Why you’ll hear about this again: Facebook is getting into the dating app space and bringing all of its consumer data privacy baggage along with it.

President Trump's choices to succeed Justice Ruth Bader Ginsburg are down to two women, both federal appeals court judges.

The frontrunners are Amy Coney Barrett of Chicago, the early favorite, and Barbara Lagoa, who is viewed as easier to confirm. The Senate confirmed Lagoa 80-15 last year, so many Democrats have already voted for her.

The TikTok deal's for-show provisions and flimsy foundations

The new deal to rescue TikTok from a threatened U.S. ban — full of provisions aimed at creating the temporary appearance of a presidential win — looks like a sort of Potemkin village agreement.

How it works: Potemkin villages were fake-storefront towns stood up to impress a visiting czar and dignitaries. When the visitors left, the stage set got struck.

  • Similarly, many elements of this plan look hastily erected and easily abandoned once the spotlight moves on.

An estimated 2.5 million+ Americans have registered to vote on Facebook, Instagram, and Messenger, Facebook announced Monday. More than 733,000 Americans have registered to vote so far via Snapchat.

Why it matters: The broad reach of social media platforms makes them uniquely effective at engaging voters — especially younger voters who may not know how to register to vote or be civically engaged.
