Contardias.com was built to be simple and honest, and this page will be no different. Here’s exactly what happens to your data when you use the site .

The calculations you perform here happen directly on your device. The dates you enter never reach our servers — we don’t store, see, or have access to what you’ve calculated.

We use Google Analytics to understand how people navigate the site — which pages are most accessed, which countries visitors come from, and which devices are used. This data is anonymous and aggregated. No information identifies you as an individual, and nothing is sold to third parties.

Google Analytics uses cookies to distinguish visits and measure sessions. You can disable cookies in your browser settings at any time without losing any functionality of the tool.

Currently, contardias.com does not display ads. In the future, we may use Google AdSense to keep the site free. If this happens, this policy will be updated before any changes take effect, and AdSense will use its own cookies to display relevant ads. You can manage your preferences at myadcenter.google.com .

If you live in Brazil, the LGPD — Law No. 13.709/2018 — guarantees your right to know what data is processed, request correction or deletion, and revoke consent. If you access this from Europe, the GDPR guarantees equivalent rights. For any questions related to your data, please contact us through our contact page .
