Is checkpoints legit? If it is I just scored 25$!?

So I downloaded the app "checkpoints" and entered hotpink797 for a bonus code that was supposed to give me extra points and it did and Im using the points for bath and body works gift card but I have to input my adress for it to be shipped to. So my question is is it safe to input my adress or am I gonna en up with a bunch of spam mail. Thanks!
