Online dating: Your profile's long and scary shelf life

Online dating: Your profile's long and scary shelf life

Online dating services have privacy policies that offer some assurances about how your personal information will be used and not used, but they don't necessarily delete your data after you've canceled your subscription and moved on

Most services use this profile data to try to convert customers who are just looking into paying subscribers. But what else can they do with it?

More are planned.
