sencha.com, activestate.com, sandisk.com, clustrix.com, and about 2000 others use LandLander. I checked the privacy policies of those four sites and none of them say they are giving away your personal information. On the contrary, they all explicitly say they aren't.
"We do not share any information about you or your company to unaffiliated third parties, except as necessary to administer the communications we offer and as permitted by law. We may use a third party service provider to for communications; that company is prohibited from using our users’ personally identifiable information for any other purpose. If you follow us on Twitter, Facebook or on other social media services, we may use information provided by these services to customize our communications to you. We will not share the personally identifiable information you provide with other third parties unless we give you prior notice and choice." - http://www.sencha.com/legal/privacy/
Nearly every company using LeadLander is breaking the law because their posted privacy policies do not state that they are giving a third party your personal information, and that third party is giving it to others.
Edit: It looks like http://formalyzer.com/formalyze_call.js is the specific js file that uploads personal information. Of the sites I listed only clustrix.com is loading that (on the contact form). The other sites seem to be using LeadLander without the form tracking.
As I understand it, in the US the FTC enforces privacy policy violations. If you don't promise your customer anything, then you're more or less off the hook (as far as I know). But if you do have a privacy policy, and you violate it, then you're misleading consumers.
And then it says: "that company is prohibited from using our users’ personally identifiable information for any other purpose."
It turns out that sencha.com might not be sending personal information. clustrix.com appears to be, their privacy policy says:
"The Personal Information we collect is not shared, rented, or sold to any third-parties. We may provide your Personal Information to companies that provide services to help us with our business activities such as shipping your order or offering customer service. These companies are authorized to use your personal information only as necessary to provide these services to us." - http://www.clustrix.com/privacy-policy
I'm not a lawyer, but as a normal native English speaker I read that as they are not going to send my name, email, and phone number to another company, who will in turn share it with with anyone who pays them. But that's what they are doing. They are selling your personally identifiable information.
