I don't know exactly. Appear in Mouse post. But I suppose is sensible or privative information or information that third persons may use.
Usually are the metadata, but I don't know if Mouser includes something else.
I fail to see how mouser is involved here or in your request...
he didn't even post in this thread (yet).
The term 'sensitive information' is IMHO too broad to be generalized into a 'simple tool', that's why I ask for context and more details. You haven't really clarified anything yet.
