I'd just like to see the extra info the app shows and change region to US which is intended by Shimano if you're in the right region.1. Because the app creator doesn't work for Shimano's warranty department.
2. Because the app is not officially approved for use by Shimano.
3. Because the app creator isn't in the business of holding people's hands LOL
Okay seriously though - the reality is this: apps that do derestriction/make downgrading possible to the end user are doing things that (here's that word again) obviously go beyond what Shimano intended. Shimano has their own official app that only does what they want user to do. It's like modding a car for higher performance; your factory warranty is void if something goes wrong as a direct result of the modifications you did that altered how the car was designed to do and made the car go beyond what was intended.
So just because the STUnlocker app (or the other apps available out there) can modify the STEPS system do these extra things, it doesn't mean that everyone who uses it will have 100% trouble-free success; case in point, the most recent "omg used the app and my bike got messed up!" thread of the week.
Thus, it's simple: if you're worried about voiding your warranty, don't do anything that puts you and your bike outside of the warranty policy. Enjoy your bike in stock unmodified form, and (one more time) obviously you'll stay covered.
But if you want to accept the risks and responsibility of wanting to modify your STEPS system to do things beyond what was intended by Shimano, then by all means download the app and enjoy the added customization.
Simple.
Obviously there is always a risk but I'm sure some options are more risky then others. Also I'm sure there is anti detection methods or tips to help make it more likely to be undetectable when needs servicing.
Some people have had problems others have gotten away with it, what are these people doing differently so that it is not detected when in for repair.
