An opt-in study of how TinyTower players are connected.
Your friends list is never read until you sign in and say yes, for that specific tower. You can stop and erase everything at any time.
We only record a friendship when both players have joined. If your friend hasn't, that connection is never stored, not even as a hint.
Older versions of this study needed you to add a bot account. That's gone. Permission travels through your Tinyburg account instead, so you can leave "Only Friend Visits" switched on.
