Mozilla reviewed the privacy of a lot of dating apps. It isn’t very pretty, but there are some that are less bad than others. Article also gives some tips on how to improve your privacy while using them.

Privacy Guides also has a “Reducing the Risks while using dating apps” section in one of their articles.

Side note: I don’t think the commenters who are saying “go outside” have really dated in years. Like it or not, it’s by far the dominant way couples are meeting now, and unfortunately it’s becoming more and more of a requirement in the modern dating scene:

I love that video. One awesome solution he brings up is letting math draw the district lines, specifically the shortest-split line method. There’s also an updated version of the method called Impartial Automatic Redistricting, that uses an approach similar to SSLM, but will only make cuts along the boundaries of census blocks (the smallest geographic unit used by the Census Bureau) to avoid cutting towns/neighborhoods in half, although it can create some odd results sometimes.

However, I think both of these would currently be illegal in the US under the Voting Rights Act for not taking minority representation into account. That is one downside to these methods, even though they’re probably still an upgrade compared to the heavily-gerrymandered system in the US. So in the US’s current system, the algorithms would have to be updated to somehow take that into account.

There are also a few other neat district drawing rules on Wikipedia that he didn’t cover which are worth a read.
