What we collect

Calculations run in your browser. The numbers you enter are not sent to any server of ours.

Hosting

The site is hosted on Firebase Hosting (Google), which logs technical data (IP address, browser) for security.

Usage statistics

We count visits and actions (for example, "opened the IMT calculator") anonymously to improve the site. We don't use cookies for this or store your IP address: we only record the page, language, device type, country (from the connection) and a random identifier that exists only while the tab is open. The numbers you type into the calculators are not recorded.

Advertising and cookies

We may show Google AdSense ads. Google and its partners may use cookies to serve ads based on your visits to this and other sites. On your first visit we ask for consent through Google's privacy message, which you can change at any time. Learn more at policies.google.com/technologies/ads.

Your rights

Under the GDPR you can request access, correction or deletion of your data. Contact: Kodingit, Lda.

Disclaimer

Results are informative estimates and do not replace the Tax Authority, Social Security or a certified accountant.
