I've used "Bill Me Later" exactly once via Paypal, to take advantage of a promotion that got me a $20 discount or credit or something (I don't remember the details exactly.)
Now, if you're anything like me, you rarely take the time to read through all the details of these things. For some reason, though, I decided to do so this time, and I was shocked
at some of the stuff I found in there. Here are a couple of my favorites:
"...we collect information sent to us by your computer, mobile phone or other access device. The information sent to us includes data on the pages you access, your computer IP address, device identifiers, the type of operating system you’re using, mobile network information, standard web log data and other information."
"In order to help protect you from fraud and misuse of your personal information, we may collect information about your use and interaction with our website or Bill Me Later Services. For example, we may evaluate your computer, mobile phone or other access device to identify any malicious software or activity."
Wow. No thanks.
