Alexey this is the issue i have been trying to bring up before and never received a solid answer from UNA. OneSignal saves the messages in their database. None of us want our users messages saved on any 3rd parties website, it's a HUGE issue. Look at what is happening with FB and other social media platforms, i had an account with OneSignal and when i saw that they save my chats with other members i immediately deleted my account over at OneSignal. As a matter a fact if UNA uses them, i am going to try to distant myself from using the Jot messenger here as much as i can, cause that means that my messages with your team and others are being stored over at OneSignal. As long as UNA uses OneSignal i can not promote my site and ask people to join. I won't lie to my friends nor will i lie to any potential client/company that wants to leave FaceCrook and those other rip offs. Please don't take this personal, but this is one of those issues that scare users away and prevent others from joining. This is a HUGE PROBLEM THAT NEEDS ATTENTION IMMEDIATELY PLEASE.
