Terms of Service

The service

Calculatrixe provides free online calculators. They are offered “as is” and “as available”. Features may change, be improved or be removed at any time without notice.

Accuracy of results

We work to make every calculator correct and describe each one’s formula, conventions and known limits on its page. Calculations involve choices, for example how a result is rounded or how a month is added to a date, and results can differ from other software or from the rules of a particular institution. Check anything important before you rely on it. The calculators are aids, not advice: do not rely on them alone for legal, medical, tax, financial or safety-critical decisions, and do not use them as proof of age or identity.

What you enter

The values you enter remain yours. Because they are processed in your browser and not sent to us, we do not receive them, claim any rights in them or take responsibility for them. You are responsible for keeping copies of results you need.

Acceptable use

You agree not to:

• use the site for anything unlawful;
• interfere with or disrupt the site or its hosting, for example by sending automated traffic that burdens it;
• attempt to gain unauthorised access to the site’s systems;
• copy the site’s content or design and present it as your own.

Advertising and third parties

The site is supported by advertising provided by third parties. We are not responsible for the content of advertisements or for the practices of advertisers. See the Privacy Policy for how advertising may affect your data.

Intellectual property

The site’s name, design, text and software are protected by copyright and other laws. You may use the calculators freely, including for commercial work, but you may not reproduce the site itself.

Disclaimer and limitation of liability

To the fullest extent permitted by law, we make no warranties of any kind, express or implied, including fitness for a particular purpose and uninterrupted or error-free operation, and we are not liable for any loss or damage arising from your use of, or inability to use, the site. Nothing in these terms limits any liability that cannot be limited by law.

Changes and contact

We may update these terms; the “Last updated” date above shows the latest version, and continued use means you accept the changes. Questions can be sent through the contact page.
