I liked the one time I used quickshare from a phone to share an image. Then I realized it uploads the content to the manufacturer’s site. There’s no doubt whatsoever that’s why Google is offering this and you can look at the EULA I’m sure you’re giving them 100% authorization to use the content.

I have to say I like quickshare. I use it with my Linux machine where I installed https://henriqueclaranhan.github.io/rquickshare/
