It might be a good idea to specify which version you're playing. It's usually very easy to back up save files when playing PC versions, but when it comes to smartphone or console versions, I'm totally clueless.

Unfortunately, they don't support such a feature on mobile, except for PC and consoles with cloud saving and manual backup on PC.

And their local data are located in the Android/data directory, which has been restricted on newer Android OS versions for security reasons.

Even if you manage to access /data, since KEMCO games and Rideon uses Unity lately, it's pretty much inaccessible and the files inside of it are usually blanks and that it has a different directory compared on PC.

Trust me, I tried this before many, many times.
