You already know the answer to this question.
I figured as much, just that I'm still very unfamiliar with linux and wanted to double-check what is and isn't cause for alarm
WiFi scanning itself does require location permissions, but I have no idea why a DNS app needs to also scan WiFi. Also, a closed-source app like that just doesn't inspire confidence. Consider using Rethink DNS from F-Droid.
I guesa location might be needed to scan WiFi, stay still, if the app is unknown and closed source it's still better to avoid it
The only thing I can think of is geolocation for CDNs. Basically to find the geographically closest server based on your location.
1000 downloads, no reviews, and just someone’s name
Regarding privacy, security, and anonymity, your own common sense will take you a long way.
Some people don't realise it immediately, though. What would you say for that one?
Well, for one, I'm not giving OP the piss for downloading the app. We all get suckered at one time or another. However, as I highlited, 1000 downloads, no reviews, and just someone’s name, is cause to pause and do some diligent searches regarding the app. If it were legit, most likely you'll find someone who has used the app and voiced their opinion. For instance, when I go to github, the first thing I want to see is when was the last activity, how many stars, how mature is the project, read the issue tracking section, etc. After a while you get a spidey sense about stuff.
Be cautious and verify.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
