Now all of that data is in the hands of Match.com's parent company, InterActive Corp (IAC). In addition to Match.com, IAC owns more than 50 Web properties, including such popular sites as Ask.com, The Daily Beast, College Humor, and City Search. It also owns Mindspark, which markets a range of browser toolbars, cursors, emoticons, screensavers, avatars, and online sweepstakes sites.

According to , the company reserves the right to share personally identifiable information with "other IAC businesses" and "other businesses with which we partner or which we carefully select to offer you products, services, and promotions through our website or offline." Users can opt out of receiving promotional e-mail and phone calls via their account settings.

However, Yagan insists that --which limits the amount of data it shares with third parties--will continue to govern the data that the site collects.

"We are not planning to share any personally identifiable information with anyone," he says. "Just because we were acquired doesn't mean we're handing over any user data. Can I sign in blood and tell you that our privacy terms will not change for all of eternity? No. Can I tell you we have no plans to do anything with any of that data? Absolutely."

Match.com declined our request for an interview, but offered the following statement via a spokesperson: "Post-acquisition, the OkCupid privacy policy will continue to apply to OkCupid user data, just as it did pre-acquisition. At this time, we have no current plans to change the policy."
