Job ID: 31289713

Budget: $250 – $750 USD

I need a website checked by a team or a professional to see how it functions how it collects data and how it sends the data out after collecting . What programs it uses.

how it functions how it collects data
what data saves
what info it takes about the user; if it saves something on the device;
info about users device, how does it knows the user is using same device upon new registration
upon what criteria does they allow users to make transactions
geolocation - with what service does it works, what it takes from the ip or from the device and if the ip is a decision in the
transaction. do they save it for the user itself or for the transaction made. how do they track the ip and do they use the dns of the ip?
about the device - does it takes the physical location? or the ip is more important? they use canvas webgl user agent etc???

with what third party do they check the data about the user ( the email phone number , background checks)
what third party websites works with
anything relevant to this concerns.
