[Feature request] Privacy policy link in FirebaseUI Auth sign-in flow

[WillieCubed]

I understand that one can add a Terms of Service URL to the sign-in flow like so:

AuthUI.getInstance()
    .createSignInIntentBuilder()
    .setProviders(...)
    .setTosUrl("https://superapp.example.com/terms-of-service.html")
    .setTheme(...)
    .build()

However, since Google Play policies require the disclosure of how personal data is used in apps, it would be nice to increase the visibility of this information during sign-up/sign-in. I'd be happy to add a method setPrivacyPolicyUrl(String url) to the sign-in builder if there aren't any major problems with the idea.

@TheCraftKid thanks for the suggestion. Let me ask a few people about this and get back to you.

Hey, @samtstern, what's the status on this?

[samtstern]

@TheCraftKid thanks for the reminder. I'd be happy to see this in version 2.0 if we can find the right place for it. Right now we show the termsOfServiceUrl only in the RegisterEmailFragment. Where do you propose putting the privacy policy URL?

Maybe we could add an overflow menu to the main auth method picker screen? Although that screen is skipped if you only enable a single provider.

[WillieCubed]

I think the privacy policy should be where the terms of service URL is. App developers should be putting the privacy policy in their apps anyway, right?

@TheCraftKid sounds good to me, want to submit a PR?

@TheCraftKid If you're busy, I'm happy to work on a PR for you. Just give me the green light and I'll go for it! 😄

@SUPERCILEX Could you check #727 out to see if there's any glaring problems? I didn't know the best way to handle the text spans for the separate terms of service and privacy policy.

I still appreciate the offer even if I ended up doing it in the end. 😄
