I've published a simillar app to the play store (a calculator for keeping track of your stats in a game) and it got denied because it had no privacy policy, and I had to add one. Maybe that's why they need to include it?
I would believe that but I'm pretty sure this is the default Google calculator. It looks like the same one that's on my Pixel. And when I click on the privacy policy thing it takes me to Google's privacy policy so who knows what the calculator is doing.
Then perhaps it's because Google should follow their own rules? I mean, I still think it's dumb to have a privacy policy on a calculator, but if that's what they ask from other devs maybe they do this to look good?
Otherwise, getting tracked by a calculator is really a low 😅
Yeah I really hope this is just them following the rules and instead of putting in the work hours for their lawyers to make a privacy policy for their calculator they just have a standard one they use and not them using the calculator to gather data. But it is Google so I wouldn't be surprised.
