I’ve sideloaded for ages and never got any spam emails or phone calls because of it. I do of course get some spam, I’m sure most people do, but to me that’s just a normal part of being active online. Never in my life got a spam call because my number isn’t publicly available.

And by the way, there are no App Store versions of emulators or cracked apps such as YouTube, which is the main reason I sideload. I don’t use my emulator that much, but I use my cracked YouTube app every single day because it has no ads.
