Nothing for me.

This is a Drift chat widget so they have your information stored somewhere, probably from some interaction you had with it on a different site. They also appear to do IP lookup as well.

Thanks, it looks like it is IP lookup, I used another phone (not mine) and they also showed my name there.

ip lookup seems like a weird way to do name lookups...

They probably check the ISP to determine if the IP is static or not, and then map the name if it is.
