First Arké push notification ever! The text obviously needs work, but very cool that it works now (this was an intimidating piece of code for me to work on). The bark mailbox system makes this very convenient to implement (those Second people seem to know what they are doing). Privacy-wise, this requires a relay to connect the app, Ark server and Apple push notification servers. The relay can connect your device ID, mailbox ID, and incoming Ark payment VTXOs. Don't like it, don't turn on notifications. I'll have to see how I can only store the least amount of data possible, since I really don't care to know what people do. The only interesting thing to know maybe would be a simple counter that tracks how many payments were made. That would at least give some broad insight into activity.
