Frequently asked

Where is the scientific keypad?
Rotate the phone to landscape. Sin, cos, tan, log, powers, roots and constants are all there.
How do I open the unit converter?
Use the converter button in the top bar. Length, weight, temperature, area, volume, speed, time, data and currency are included.
Why are the currency rates slightly different from my bank's?
Calc² uses the European Central Bank's daily reference rates, published once per working day. They are a reference, not a dealing rate, so a bank or a card will always differ a little.
Do the currency rates work offline?
Yes. The last downloaded table is kept on the device and keeps working without a connection. It refreshes itself once you are back online.
How do I clear the history?
Open the history, then use the clear button. It asks once before erasing, and it cannot be undone.
Can I change the language?
Calc² follows your phone's language automatically, in 30 languages. Change the phone's language, or the per-app language in your phone's settings, and Calc² follows.
Does Calc² collect anything about me?
No. See the privacy policy. No accounts, no analytics, no ads, no tracking. The only thing it ever downloads is a public exchange-rate file.
Is there a subscription?
No. Calc² is bought once and it is yours. No ads and no in-app purchases.
