I just gave it a test run with a nonsense vin, to see if they wanted more info. they don’t. Your vin is not private information - its connection to you is (sort of, the dmv’s records are actually public). So if you cared to use this tool, just use a vpn and you’re all set.

It’s probably wise to assume everyone on the internet is out to get you. But to provide tools online, you have to ask for information.
