Pushed by recent legislation and smart disclosure initiatives, the Personal Cloud emerges and holds the promise of giving the control back to the individual on her data. However, this shift leaves the privacy and security issues in user's hands, a role that few people can properly endorse. This demonstration illustrates a new sharing paradigm, called SWYSWYK (Share What You See with Who You Know), dedicated to the Personal Cloud context. It allows each user to physically visualize the net effects of sharing rules and automatically provides tangible guarantees about the enforcement of the defined sharing policies. The usage and internals of SWYSWYK are demonstrated on a running prototype combining a commercial Personal Cloud suite (Cozy Cloud) and a secure hardware reference monitor (PlugDB).
