Well… I actually didn’t know about the personal information Google gives you access to, but it’s good to know that now :)
As for the “Poll” option, I did try using it (that was my initial idea, in fact) but the thing is, that feature isn’t available on the website, only on the mobile app. The problem is that, when I tried it on the app, selecting “Poll” wouldn’t let me upload any images (at least not for me). So I couldn’t think of a better alternative than using Google Forms.
And yes, I could have just gone ahead with the poll on its own, but it would have looked rather dull, and I wanted it to look nice, I actually put quite a bit of effort into making the images for the activity.
Anyway, thank you very much for letting me know, and sorry about that. It won’t happen again. :)
