-    If you sign-up at <https://on-air.nicegui.io> you get a token which could be used to identify your device: `ui.run(on_air='<your token>'`).
-    This will give you a fixed URL and the possibility to protect remote access with a passphrase.
-
-    Currently On Air is available as a tech preview and can be used free of charge (for now).
-    We will gradually improve stability, introduce payment options and extend the service with multi-device management, remote terminal access and more.

+    fixed URL (`https://on-air.nicegui.io/<my-org>/<my_device_name>`).
+    The device is then identified by a unique, private token which you can use instead of a boolean flag: `ui.run(on_air='<your token>'`).
+    If you [sponsor us](https://github.com/sponsors/zauberzeug), 
+    we will enable multi-device management and provide built-in passphrase protection for each device.
