Privacy Policy
Updated on July 6, 2026
This Privacy Policy explains what data Contania processes when you use our calculators, why, and your rights under the Brazilian General Data Protection Law (LGPD).
Who we are
Contania is a free online calculator site. We are the data controller. For any privacy matter, contact us at contato@contania.app.
What we collect
You do not need an account or personal data to use the calculators — the values you type are processed in your browser and are not sent to or stored by us. We only collect aggregated navigation data (via analytics) and cookies/identifiers used by measurement and advertising services, subject to your consent.
How we use data
We use navigation data to run and improve the site and, with your consent, to display ads that fund the free service. Our legal bases are legitimate interest (essential metrics and security) and consent (non-essential analytics and advertising cookies).
Cookies
We use essential cookies (e.g., to remember your theme and consent choice) and, with permission, analytics and advertising cookies. See our Cookie Policy for details and controls.
Advertising and Google AdSense
We may show ads via Google AdSense and partners, which may use cookies to serve and measure ads. We use Google Consent Mode: until you accept, advertising and analytics cookies stay disabled. Learn more at Google Ad Settings (adssettings.google.com).
Data sharing
We do not sell your data. We may share it with providers operating the site on our behalf (hosting, analytics, advertising), or when required by law. Some providers (such as Google) may process data outside Brazil with appropriate safeguards.
Your rights (LGPD)
You may request confirmation, access, correction, anonymization, portability or deletion of your data, and withdraw consent, at any time via contato@contania.app. You may also complain to the Brazilian data protection authority (ANPD).
Security and retention
We apply reasonable technical and organizational measures. As we keep no accounts, the data we process is mostly aggregated and temporary, retained only as needed.
Children
The site targets a general audience and does not knowingly collect data from minors. Contact us if you believe a child provided data so we can remove it.
Changes
We may update this policy. The current version is always the one published here, dated at the top.
