Hello everyone, maybe someone came across this question, where can the user data be stored, that is, for example, there is currency in the game, the user earned some money, then deleted applications, then after a week he installed again and the old data was pulled, maybe there was some then a data storage service or something like not having to do it yourself and not to rent a server. on Android

    You need each user to have a unique identifier. For example, ID in a social network. After that you can save somewhere a key / value pair of the form ID:value

    You can save in different ways. For example, you can simply edit a text file in your cloud (GDrive, DropBox etc). But it is better to use a free (conditionally) cloud type FireBase. In the latter, the data is stored as a JSON file and there is a library for simple recording / receiving values. But for free there is a certain threshold for the number of connections to the cloud per second.
