When you use a dating app, or many other apps for that matter, you’re also giving away data in less obvious ways. (You can use your phone's permissions settings to limit some of that tracking.)
Most ask for access to your location, and many sponge up details such as your contacts, your photos, WiFi and network connections, and files on your device. They gather a lot of data from your smartphone, too.
There’s what you tell them directly, such as your name, occupation, what you’re looking for in a partner, and your sexual preferences. As you swipe, type, and meet up with online matches, dating apps are collecting all sorts of information.
