Can a hotspot owner see your search history?

I recently started working for TELUS and received an iPad with unlimited data for as long as I work there. I'm currently using that iPad to hotspot the device I'm using to post this. Will Telus be able to see what I'm using the hotspot for?

Is it possible to create e-book for both iPad and Kindle on InDesign?

I'm wanting to create and sell an e-book, ideally being able to compile it in one InDesign document, sell it, and make sure it looks good on both iPad and Kindle.

What dimensions should I make the document? What works best across both platforms?

Thanks!

If I use a small drawing tablet, but large canvas size, will the picture be able to be enlarged/printed at high quality?

I'm used to working on small screens for artwork but as I want to take my digital art a little more seriously I'd like to buy a decent tablet. I often see professionals with large tablets (around A3 size) to make sure that their work can be printed on a large scale at high quality… But I would much prefer working on a smaller screen, around the size of an iPad mini or maybe a little bigger.

I was thinking if I used Adobe Photoshop for example, if I simply adjusted the canvas size to A3 (And obviously worked on it zoomed out to fit the whole thing on my smaller screen), if the picture would be able to be printed out at A3 in high quality and non pixelated. It seems like a simple enough idea to me, but I'm not sure if it would work or if problems like lagging would arise because of this.

Any ideas, experience or information is appreciated. Thank you.
