Best answer: FaceApp does collect some information from you, but it doesn't data mine you. It's no more dangerous than uploading photos to Facebook. The big difference is this company is Russian based, which could be a concern for some people.

Protecting your Privacy
FaceApp is the newest viral app thanks to its ability to show you what you might look like under different circumstances. This app first became popular a few years ago for its gender-swapping filters, and now it's having a resurgence thanks to an aging filter. However, along with it's renewed popularity, there are particular security and privacy concerns, precisely because the app is based out of Russia.
The thing to remember to begin with is that privacy is not always something that is easily achieved on the internet. Every time you upload a photo to Facebook or share your location on Instagram, you are chipping away at your personal privacy. In much the same way, FaceApp can be a privacy risk, but only if you're giving it more access than it needs. It's not doing anything different than several other apps available through Google Play; the big difference is where the company who owns the app is located.
Now, this isn't to say that FaceApp doesn't save any of your data. Specifically, it keeps the photos you upload to its servers. This means when you take a picture to apply aging or gender swap filters, it gets saved. However, there is no indication that something shady like saving every photo in your gallery occurs. Owners of the app have previously stated that user photos are deleted off of their servers, but there isn't any way to check on this, and users don't have the ability to delete their own data. However, what is happening is no more egregious than what occurs when you upload something to Facebook or Google.
