You recently calculated 34*5+1. Do you want to buy a new washing machine?

It's because of the log function

Something about this just doesn't add up.

"Continue to use of all the numbers you love!*

Starting August 1st, numbers 9, 7 3, 2 and 0 will only be available to members subscribed to our premium Calc+ tier.

Please don't log my calculator inputs it's more embarrassing than my browser history is.

My calc app also has its privacy policy there. It says

OpenCalc does not collect any user data.

"=" [locked] Infix subscription required

...

"base ten" [locked] subscription required, reverting to octal

GrapheneOS + network permission toggle
Or just use a FOSS app from F-Droid

They want to monetize any proofs you find.

Now get to work crunching numbers.

It's possibly compliance. I know google requires you to have a privacy policy to even publish an app, no matter what.

In fairness, I've had to write a privacy policy due to store restrictions. It boiled down to "everything stays on your phone. I don't collect your data, I don't want your data, I don't even have a backend server that could be collecting your data. If you find my app sending telemetry of any kind, please tell me immediately because that should not be happening"

That being said, this doesn't exactly inspire confidence

Why didn't every privacy concerned people switched to foss already?

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?

material you colors are pretty ugly

Is this even material you it looks like it

Gotta love that internet access is implicitly provided in Android now /s

They want your equations on the off chance you accidentally solve one of the Millenia Prize problems.

Yes!

My Xiaomi Redmi 11 keeps telling me the Calculator can't use the network (why?) and keeps asking me to accept the privacy policy.

Also the app wallpaper - the one that changes the locked screen background image (important complex stuff /s) - also keeps asking me to accept the privacy policy.

And, as far as my reading of the policy goes, these privacy policies are just the one, it's not a different one for each app.

They are just promising not to share with the government or any private entity that you are the idiot who had to use a calculator to find half of 17, just in case you were worried about someone finding out.
