The CalcuBoss name and logo, and the app’s text, exercises, tips, illustrations, sounds and code are protected by copyright.

You are welcome to use the app freely at home and in class. Any other reproduction or distribution of its content, in whole or in part, requires prior permission, which you can request using the contact form.

Credits

• Fonts: Nunito (© The Nunito Project Authors) and Lexend (© The Lexend Project Authors), distributed under the SIL Open Font License 1.1. They are bundled with the app and never loaded from another website.

Personal data and cookies

CalcuBoss shows no ads and uses no advertising trackers or third-party scripts. The site sets a single cookie, cb_session, which is strictly necessary to stay signed in to the parent account. CalcuBoss measures its own audience with usage statistics that contain no names or email addresses, and you can turn them off in the app settings. All the details are in the privacy policy.

Liability

CalcuBoss is ad-free. The trial without an account and the parent account are free; the Premium family subscription is paid. The offers, prices and subscription terms are set out in the terms of sale and use. The publisher takes care to keep the educational content accurate, but cannot guarantee that it is entirely error-free or that the service is always available. If you spot a mistake, please report it using the contact form.

Governing law
