You can always password your device.

Lol, I had a family member spend gems too. I honestly just keep my device locked as @LilCricketPa said, doesn't matter how badly they wanna try playing it, the app stays locked.

Desktop is never logged in, nor is the password saved for the account, so that'll be a bust for anyone that tries as well.
