Privacy policy

This page explains, in line with Brazil's General Data Protection Law (LGPD, Lei nº 13.709/2018), which personal data Calcula Já processes, why and for how long. The short version: almost none.

Who is responsible

The data controller is Juliana Costa, who runs the site from Curitiba, Paraná, Brazil. For any privacy matter: hello@canivetotool.com.

No account, no cookies, no tracking

There is no sign-up or login. The site uses no cookies, no analytics tools, no social media pixels and no ads, and it loads no third-party scripts.

The values you type

Salaries, dates, number of dependants, revenue, phone numbers and messages entered in the calculators and WhatsApp tools are processed only in your browser, with JavaScript. They are not sent to our server or stored by us.

Values only become part of the page address (URL) when you yourself use the “Copy simulation link” button. That link stays with you and whoever you send it to. If someone opens it, the server receives the page request like any other visit (see “Server logs”), but we do not store simulations in a database.

Local storage in your browser

We use your browser's localStorage only to remember your chosen language and whether you have dismissed the notice shown on the site. This information stays on your device, is not sent to us and can be deleted at any time by clearing the site's data in your browser.

Language suggestion (/api/geo)

To suggest a suitable language, your browser calls /api/geo. The server looks up the country for your IP address in a local database (DB-IP, see the credits), uses the IP only in memory for that lookup and does not record it. The response contains only the country code.

Server logs

As with any website, the hosting server keeps standard technical access logs: IP address, date and time, page requested and browser identification (user agent). They are used for security, troubleshooting and aggregate usage statistics, on the basis of legitimate interest. They are kept only as long as needed for those purposes, are not used to identify visitors and are never sold.

E-mails

If you write to us, we use your address and the content of your message only to reply and fix whatever is needed. We do not add anyone to mailing lists.

Sharing

We do not sell or hand over personal data. It may only be disclosed to authorities where required by law or court order.

Your rights

Article 18 of the LGPD gives you, among others, the right to confirm whether we process your data, access it, correct it, request anonymisation, blocking or deletion, know who it was shared with and withdraw consent. To exercise any of these rights, write to hello@canivetotool.com. You may also complain to Brazil's National Data Protection Authority (ANPD).

Changes

This policy may change when the site changes; the date below shows the version in force. See also the terms of use.
