On Kik Messenger, if i block someone can they still view me on their contacts & see our conversations?

Blocking someone on Kik Messenger will not delete you from their contact list. They will still be able to view your previous conversations.

When a message is sent from you to another Kik user, the message exists on your device and their device separately. Once Kik servers have relayed the message, they delete it from their system. Blocking a user will not delete the messages that have already been delivered to them.

Kik Messenger was the first product produced by Kik Interactive. It is a cross-platform, customizable, fast-operating messaging app available for most smartphones including iPhone and Android based devices. The first goal of Kik Interactive was a music sharing app exclusively for BlackBerry. Along the way, they accidentally created the breakthrough app Kik Messenger.
