Privacy policy
This version processes names and dates of birth entirely in your browser. They are not transmitted to CalcularRFC or saved in a database.
Form details
Values remain in the page’s memory while it is open. They are not included in URLs, saved to local storage or sent to SAT services. The tool does not restore the previous result after reloading the page.
Appearance preference
If you choose light or dark mode, only that preference is saved in your browser’s local storage. You can remove it by clearing site data. The published version uses Ezoic for advertising and associated measurement. Its scripts may use cookies and technical data according to consent choices and applicable rules. The calculator does not include your names, birth date or amounts in advertising or analytics events.
Hosting and external links
The hosting provider may process technical connection information, such as IP addresses, to serve and protect the site. Links to SAT, IMSS and other services lead to websites with their own policies. Those institutions handle details you enter there.
Contact messages
If you email the project, your email provider and the recipient process the message to respond to it. Do not include personal identifiers or documents. Martin Kreitl is responsible for the project and can be reached through the contact page.
