Just recently discovered shelter, too. I would have gotten it way earlier if I knew. Had to install an app that I knew was too grabby with data (luckily for one-time use) and only found out about shelter researching how to stop it from spying too much.
And then there’s me, always setting my alarm clocks to some odd numbers like 7:03 on purpose. Don’t really know what that purpose is, but hey :)
