Privacy Policy

What You Enter

The calculator runs in your browser. The incomes, deductions and contributions you enter are used there and aren't sent to us.

Your income is added to the page address, for example ?income=100000, so you can bookmark or share a result. Anyone you send that link to can see the figure, and opening the link sends the address to our host like any other web request.

Analytics

We count visits with Cloudflare Web Analytics, which doesn't use cookies or follow you across other sites. It records things like the page you viewed, the site that linked you here, your browser and your country.

Hosting

The site is hosted by Cloudflare, which processes your IP address and request details to deliver pages and protect the site from abuse, under the Cloudflare privacy policy.

API and MCP Server

The figures sent to the API or MCP server are used to compute the response and aren't stored. Cloudflare limits how many requests one IP address can make.

Stored on Your Device

Your choice of light or dark mode is saved in your browser. The browser also keeps copies of pages you've visited, so the calculator works offline. Clearing your browser's site data removes both.
