For its part, Facebook says that it isn't going to “commingle” the data by merging information in order to identify the Move users who also are on Facebook. “Facebook is not adding Moves user data to a Facebook user’s Facebook account,” a spokesperson says in an email to MediaPost. “But, Facebook will be providing support and services to the Moves app and to be able to do this, we have to have access to the data that Moves already collects from its users.”
Regardless of the company's current plans, the new policy's wording appears to enable Facebook to draw on data about Moves' users in ways they couldn't have anticipated when they began using the app.
Given that history, it wouldn't be surprising if the FTC intervenes again, and persuades the company to promise that it won't use Moves' trove of data in ways people didn't expect.
