These questions are easy to answer.
If female genital mutilation "direct harm"? Yes.
does the same apply to circumcision of males? Not to the same extent, because the harm is less - despite using the same word, cutting off the foreskin is objectively less harmful than cutting off the clitoris.
However, this is an area where the prevailing opinion is shifting as we speak. Male circumcision used to be normal (in the US), now it's considered in most polite circles to be somewhere between antiquated and barbaric. The loudest argument in favor seems to be "it's my religious tradition!" but ask the mormons how that argument faired WRT plural marriage and excluding blacks. Public opinion shifts slowly but it's not hard to imagine a future where even religion doesn't cut it as an excuse for cutting off bits of a baby's junk. We may revisit this question in a few more decades.
Is it ok for parents to see where their children are? Yes. Parents in every modern society are granted extremely broad powers over their children.
If in a culture the husband is viewed as the guardian of his wife, is it ok if the husband uses the same app for his wife? No. Women are not property. That's the moral judgement of modern society. Cultures which violate this moral judgement should do so without our help.
These are not thorny issues or deeply philosophical problems.
