What Information Do We Collect?
The PCalc applications on iOS and OS X do not in general collect any individual information, or connect to the internet. They're just calculators!
The one exception is that if you use the currency conversion feature, PCalc will talk to the pcalc.com website, in order to download the latest set of exchange rates.
During this, some information about your copy of PCalc is logged as part of the conversation. This is strictly limited to your device's IP address, the version of PCalc you are using, the type of device PCalc is running on (e.g. iPhone or Mac), the version of the OS, and your primary language setting. That's pretty much the same kind of thing we'd get if you just visited our website with your browser.
Automatic downloading of the currency rates can be switched off in the Advanced section of the settings, and this will prevent PCalc from connecting to the internet at all.
What Do We Do With The Information?
This information is occasionally used in an aggregated fashion to see what kind of devices people are running PCalc on. This helps us decide such things as how far back to support various operating systems, which languages we might want to add in the future, and so on.
Most of the time, we forget to look at it anyway.
If you have iCloud Drive enabled and create any user functions, conversions, constants, or key layouts, these will be uploaded to Apple's iCloud servers, so they can automatically sync across to your other devices. We don't have any access to that information. You can switch off iCloud syncing in the same section of the settings.
If you have any more questions, please feel free to get in touch.
