How long can a facebook application store your personal data after you quit?
I’ve been wondering about this question for some time because if you quit and re-join an application, the application somehow remembers everything about you. This doesn’t seem to respect user privacy at all. I did a few searches to find the answer to my question, and found some answers at the Facebook Developers Wiki on Storable Information.
User data you receive from Facebook that you can store indefinitely:
uid User ID
nid Primary network ID
eid Event ID
gid Group ID
pid Photo ID
aid Photo album ID
flid friend list ID
listing_id Marketplace listing ID
page_id Facebook Page ID
proxied_email Placeholder email addresses for your users
notes_count Total number of notes written by the user
profile_update_time Time that the user’s profile was last updated
When you delete an application, Facebook tells you this “If you remove XXX application, it will no longer have access to your data and be removed from your profile, bookmarks, and Applications Page,” so why is there this contradiction? Why are applications permitted to store user’s personal data indefinitely, while we are told the application will no longer have access to our data?
Indefinitely is a long time.
