Hello @tanasetaro, the real-time database has four main functions.

- The get function

- The save function

- The AddListener function

- And the RemoveListener function

To save someone’s data you will need to perform a sign-in function to get the users ID. Then you can perform a Save function using the ID from the sign-in as the key and store their data in an object form.

Have a look at this example I have made.

(Please note you will have to supply your own API key and database URL)
