Facebook Connect De-Auth rules

It was claimed that when a user de-authorizes your Facebook application, the Facebook API terms of service require you to delete all data about the user that you got from the API. This includes fields you pre-filled that the user then submitted.

Facebook does provide you with a de-auth callback if you want one, but there is no explicit mention of it in the ToS. The ToS does say you must remove user data “upon request” and that you have to provide a way to make such a request.
