Well, maybe not everything. But the first time I encountered this river and someone 'fell in,' he completely forgot about Retrospec. No memories of his past life and no memories about the app or any of the stuff that'd happened. He got it all back, but not until we made it back to the city. So if you have any useful skills or memories, kindly don't wipe them.
