Privacy
The short version: there is no account, no tracking, no analytics, and no database of anything you type. The calculation runs in your browser.
Calculations and URLs
When you pick a comune, the browser fetches that comune’s tax rules and then runs the whole calculation locally. The salary, the number of children, the payroll options and other inputs are used locally for interactive recalculations, rather than being submitted to the remote MCP server by the calculator.
The calculator updates the address with your comune and gross salary, even when you start from the home page. This address update does not itself submit the calculation. Opening, reloading or sharing an address such as /comune/milano/30000 sends that path to the server. The path can appear in browser history and hosting or network logs.
Share links
A share link encodes your inputs in the fragment of the URL, after the # character. Browsers do not send the fragment in HTTP requests, but the path before it still includes the comune and gross salary. The fragment is not encrypted: anyone you send the link to can read every input in it, including family and payroll options.
Receipt images are drawn in your browser and never uploaded.
What is stored on your device
Two preferences, in localStorage, both optional: your chosen theme and your comparison currency. They never leave the browser and clearing site data removes them. There are no cookies set by this application; the content delivery network in front of it may set its own bot-management cookie.
What leaves the server
The optional currency comparison fetches dated ECB reference rates from a public exchange-rate provider. That request carries no information about you. It asks for public rates and nothing else. No salary, no comune, no identifiers.
There are no analytics scripts, no tag managers, no advertising pixels and no third-party embeds on any page.
Agents and the API
The public API and the MCP server are stateless and keyless. Unlike interactive browser calculations, remote MCP calls send their arguments to this server for processing. The application does not save calculation inputs to a database. Hosting and network providers may process request metadata for delivery, security and diagnostics.
