 This is a purposefully "simple" application backend made specifically for _my_ apps. It's purpose is to collect minimal (only what's absolutely necessary) amounts of data while still fulfilling all my needs. I've found that other, off the shelf options such as Firebase are a bit heavy on the data collection. Plus I like to make things :P.

+  key: "API Key",
+  death: -1, // unix timestamp when the key is no longer valid. -1 means there is not expected expiration (that can change in the future)
+  perm: {
+    user: true, // create and login users
+    log: true, // log users
+    crash: true, // crash reports
+    // further permissions can be added as needed
+  }
