An elegant yet powerful calculator app.

Privacy policy

The Calculabo app functions entirely offline. Your activities inside the calculator are never sent over the internet. If you are connected to the internet, this connection is only used to check for updates, to count usage (but not the nature of the usage), and to show the documentation if the help button is clicked.

To protect your privacy, the app and website are available over a secure HTTPS connection.

Google uses cookies, including the DoubleClick cookie, to serve relevant advertisements on this website, based on your prior visits to both this website and other websites on the internet.

If you prefer, you can disable the use of the DoubleClick cookie for interest-based advertising via Google Ads Settings. This sets an opt-out cookie to remember that preference.

It is always possible to block cookies or clear previously set cookies in your browser. See the help files of your browser for information. Be careful not to accidentally clear the opt-out cookie mentioned above, if set.

Note that some browsers offer an alternative mechanism to indicate a preference not to be tracked. Unfortunately, Google currently does not support this mechanism.
