ClassAdLister will not share any information about anything you do while using ClassAdLister period.
Why would you believe such a statement? Because there is no way for us to gather your information even if we wanted to. ClassAdLister has no server component. There is no information sent to the cloud or anything else for that matter. ClassAdLister uses information you store on your device to populate web pages via a custom browser derived from the same libraries used by the stock browser. It is very simple, lightweight, and not really any different than browsers saving your username and password when logging in to sites. ClassAdLister uses similar techniques to populate the rest of the information needed to post an ad like title, price, and description for example. It uses a database stored on your device with information you enter to populate these fields.
