Google acquired Bump -- developer of an NFC-like file sharing app with the same name and a photo sharing service called Flock -- back in September, and both projects will shut down January 31st. CEO and cofounder David Lieb announced the discontinuation of both products on the Bump blog, saying his team is "deeply focused on our new projects within Google." That bodes well for their mission of enhancing sharing on mobile devices, but the bad news for Bump and Flock users is that this shut down means everything must go.

After January ends the apps will no longer function, they'll disappear from the App Store and Google Play and all stored data will be deleted from servers (locally saved files or photos will remain in place). Any of those millions of users can still keep their data though, just open up the app anytime in the next month, and follow the instructions shown (tap the "i" menu on iOS or "More" on Android). Afterwards, Bump will send over an email with a link to let you download all of your stored data.
