Session Timeout in Kinetic

We are starting testing Kinetic and I have 3 questions

On Kinetic thick client does the usual 15 minute license expiration happen after inactivity?

With the web client do you lose your work if your license expires? I thought I lost my work at one point while playing around. Wondering if it was due to timeout.

Is there any difference between the SAAS handling of this and private cloud?
