Privacy
Figures typed into calculators are not sent to our servers. The maths runs in your browser.
Your browser keeps pay and margin in localStorage on this device only, to pre-fill the next tool. Values never go in the URL, so they do not leak through history, analytics or referrers.
We do not ask for CPF, phone, email, payslips or a login. There is no user account.
Who handles data
CalculaBR is run by its editorial owner, who acts as controller under Brazil’s General Data Protection Law (LGPD, Law 13.709/2018). The site does not publish a company name, tax ID or address; the channel for any privacy matter is the contact email shown below and in the footer.
Because the maths runs in your browser, the site does not receive or store the figures you type into the calculators.

What is saved on your device
When you use the net-salary calculator, the margin calculator or the home-page simulator, the site automatically writes a localStorage entry named calculabr.session.v1. It holds gross pay, number of dependents, net pay, INSS, income tax, estimated margin and the time of the last update, so the next calculator can be pre-filled.
This record stays on your device, is not sent to our servers and never appears in the URL. To remove it, clear the site’s data in your browser settings or use a private window.
Cookies and tracking
The site sets no cookies of its own, has no sign-up or login, and uses no audience analytics, advertising pixels or profiling. If we ever add audience measurement, this page will be updated first and we will only receive aggregate data such as pay bands, never the exact figure.
Third-party services
To deliver pages the site uses Cloudflare infrastructure, which processes technical connection data such as IP address and browser type. Text fonts (Figtree, Fraunces and IBM Plex Mono) are loaded from Google Fonts, and a platform script is loaded from the grok.com domain. In those requests the providers receive your IP and browser details under their own policies. The site does not send them what you type.
If you write to us
If you email us, we process your address and the message only to reply, on the basis of your consent (LGPD, article 7, I), for as long as needed to resolve the matter. Do not send a CPF, payslip, bank details or internet-banking screenshots.
Your rights
LGPD article 18 gives data subjects, among other rights, confirmation of processing, access, correction, anonymisation, blocking or deletion of unnecessary data, portability, deletion of data processed with consent, information about sharing, and withdrawal of consent. To exercise any of them, write to the contact email. You may also petition Brazil’s data protection authority (ANPD).
