Pathetic. I was totally in love with this app until I changed my phone. I lost the phone, and when I installed the app in my new phone, everything was gone. My habits, data for last one year, every damn thing. And I have purchased premium of the highest cost. There's no way to restore my data or contact the devs. If you cannot save on JSON file of mine in your cloud, please explain why I should buy premium? There is a sync option in the app. Don't tell me I should have manually "synced" my stuff
