Nope, nope, nope. You said you “can confirm” which indicates that the details have been shared with you which is the bit I’m calling bullshit on. Possibly these folks are silly enough to share with you, I guess anything’s possible.
Non-disclosure agreements are used for a variety of reasons mate, are not an admission of anything, and are an ‘agreement’ between 2 or more parties. I’m going to go ahead and assume you understand what an agreement is since you English so well.
