Terms of Use

The service

CalculaBoa provides free tools with no sign-up, "as is" and without warranties.

Results are estimates

Calculators use public formulas and tables and show when each table was last updated. Results are still estimates for guidance and do not replace an official calculation or a professional.

Acceptable use

You agree not to use the tools to:

• send spam or unsolicited messages;
• harass or deceive others;
• violate WhatsApp's or other services' terms;
• do anything illegal.

Trademarks

CalculaBoa is not affiliated with, endorsed or sponsored by WhatsApp or Meta Platforms, Inc. WhatsApp is a trademark of its owners.

Advertising and partner links

The site shows ads and, on some pages, partner links. If you buy something through a partner link, we may earn a commission at no extra cost to you. Ads and partner links are always labelled as such, never sit between a tool's inputs and its result, and never change a result.

Embedded calculators

Any site may embed, free of charge, the calculators offered on “Calculadoras para o seu site” (Portuguese only), as long as the “Calculadora por CalculaBoa” link stays visible and the content and results are not changed. We may change or stop the embedded calculators at any time. Results remain estimates, as everywhere on the site.

Changes

We may update these terms. The date below shows the current version. Questions: [email protected].
