Using a Device Only

Device Only deployments

FREE

This kind of Deployment is available on the FREE tier.

With this kind of Deployment, you can run any Apps you create on mobile devices.

No backend

It is limited in the sense that no backend is connected, so data created on the device is not backed up in the cloud, and would be lost if the device is lost or the data on the device is corrupted in some way.

Authentication is via Google

Without a backend, there is also no platform to provide authentication, so for Device-only deployments, Google authentication is used.

This way, you can make use of User Profiles, email autofill fields, etc,
