IIRC Google wants it to be accessible in one click, so I assume this would be out of the question.
Unless you need sensitive or restricted scopes (which aren’t needed for discourse), no. Although users with higher security settings may potentially run into problems signing in, but I expect this to be rare.
Most sites have a link in the footer, which is what I assume they were after.
That said Google is not known for consistent enforcement so it may have been an overzealous reviewer for my case.
Yeah I’m aware the guidelines only say it must he “accessible”, but they can and have been obnoxious because they deemed it “not prominent enough”.
There are other theme components that would allow people to put it somewhere else if needed? eg Custom Header Links The preview for that has a privacy link as an example. I’ve not gone through the Google review myself though, so I don’t know the intricacies of exactly what they want.
