You can’t, generally. Any program you install can do just about everything you can. As such, the main methods of defence against apps misbehaving are a) don’t install things if it can be avoided, and b) use open source software where possible.
We live in an era where there are various patchwork fixes to most glaring dangers, like, antivirus software, that protect user just enough from consequences of their own actions that the whole world won’t go down in flames, but I do recommend anyone trying to take a step back and just take steps protecting their devices on their own. Don’t run code you haven’t checked yourself, or have some other reason to trust. Meaning, open source software if possible, and that only if you cannot avoid installing the app.
