We created Sesame because we believe private ownership and nuanced control leads to better communication. Sesame's Cognitive Messengers audit every message and their attendant permissions independently for you, and give you the ability to take back your messages from any device, whenever, forever.
...So if you break up two years from now, you can take all of your messages and pictures back :)
Any plans for an Android app? This sounds like something I want to try out.
