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 some kinds of tools online, you have to ask for information.
