> Is it the right moral choice to protect the privacy of a cheater?

Is this spyware used to find out if someone is cheating? If so, it means you'd install it, and violate their privacy, without knowing if they are a cheater, so the point is moot.

I was not referring to the app, but in general to discover a cheater you'll most likely violate their privacy.

My point is that privacy in a relationship is a relationship thing, and the moral choice for me would be to not interfere in other peoples relationships. This includes not judging you if you use spyware on your wife.

I'm not sure this is true. There are often clear boundaries, like secretly observing them in public versus accessing their private phones.

> privacy in a relationship is a relationship thing

but it's also a privacy thing. Is domestic abuse a relationship thing? That would also interfere with a relationship.
