Question about Secure Folder

[Android Central Question]

OK, this may be quite a funny question, but just wondering how it works.

I have Tinder and a few other dating apps within my Secure Folder (no, I don't have a partner, basically it's for reasons as this is a work phone)

I have used Tinder lots of times before, and I know that it connects through your facebook to get bio, info, photos, etc.. well, everytime I used tinder previously, it never ever showed any of my facebook friends as potentical matches on tinder.

However, since I installed Tinder in the Secure Folder, it shows lot's of my facebook friends, would this be because facebook isn't in my Secure Folder?

I don't think you need to be an expert in Tinder of Facebook to work it out, but I thought it might be because one of them is in secure, and one isn't. Do apps within the secure folder interact with apps outside it at all?

Random question maybe, but hope someone can help!

Swiftkey works in both for some reason. The email address I set up in secure folder comes up as a word prediction outside of it. What I really found odd is that I didnt even install Swiftkey in Secure Folder so didnt think it would be an option to even use.
