TudoCalc is run by one person, not a call centre — which has an upside: whoever reads your message is the person who writes and fixes the calculators.

Responsible: Rafael Rossi
Email: rafaelrossi.apps@gmail.com
Response time: usually within 3 business days; 15 days at most for personal-data matters.
Languages: English and Portuguese.
Where we are: Brazil. The site is operated remotely; there is no walk-in office.

Found a calculation error?

This is the most valuable email you can send us, and it takes priority over everything else. So we can reproduce and fix it the same day, please include:

• the page address (for example, tudocalc.com.br/en/bmi);
• the values you entered, exactly as you entered them;
• the result you got and what you expected instead;
• if possible, the source for the correct figure (an official table, a payslip, a standard).

When an error is confirmed, the calculator is fixed and the page's revision date is updated — that is how you can tell the correction actually shipped.

Suggest a calculator or a topic

Tell us which calculation you needed and could not find. Suggestions that describe the real situation ("I need to know what's left of my pay after switching to contracting") are far more useful than just naming a formula, because they reveal which fields the calculator needs.

Embedding a calculator on your site

Any calculator can be embedded via iframe from /en/embed/<calculator>, free of charge, as long as the credit link stays visible — the conditions are in the Terms of Use. If you run an accountancy, an agency or a firm and want a calculator tuned to your case, write and describe the scenario.

Press, partnerships and advertising

For quotes in reporting, use of the site's data, or commercial proposals, start your subject line with "Press" or "Partnership". Ads shown on the site come from Google AdSense and are not negotiated directly with us.

Privacy and personal data

Access, correction and deletion requests, and any privacy question, go to the same address — but read the Privacy Policy first, which explains why in practice the site has almost no data of yours to hand over: the calculations run in your browser.

What we don't do

We don't give individual advice. We can't tell you what your severance will be in your specific case, whether a mortgage is right for you, or what a test result means — for that, see an accountant, a lawyer, a financial adviser or a doctor. The calculators exist so you walk into that conversation knowing the order of magnitude.
