iPad questions

[vanillacourage]

1. How do I sign out of the PB app on the iPad?

2. It somehow set up to sync with my iPhone and now my texts come through on the iPad. DH and I share the iPad and while I'm not up to anything illicit I don't need him reading all my texts. How to turn it off? (eta -I see where to get it to stop syncing but you can turn it back on with one swipe. Any way to disable?)
