Does viveport allow customs saves like SteamRemoteStorage

[mjean]

With Steam you can save data bytes with 

SteamRemoteStorage.FileWrite(filename, data, size);

Is there something similar in Viveport?

Or am I forced to use the Stats API?

@mjean No, Viveport does not currently have Cloud saves. You can use the Stats API if the functionality works for your use case.
