Privacy Policy
Short version: the numbers stay in your browser.
Short version
The area figures you type are read by the script in this page and written back into the same page. Nothing is uploaded, stored or shared, and there is no account.
What happens to your inputs
- They stay in the page. The script reads the gross area, the shared-area percentage, the wall allowance and the unit, computes three areas and updates the result panel.
- No upload. There is no request carrying the numbers. The calculator works with the network disconnected once the page has loaded.
- No storage. Nothing is written to local storage, cookies or a database. Reload and the 100 m² example returns.
- No analytics of inputs. The page does not record which areas were entered or how often the form was used.
Why a floor plan is sensitive
The size and layout of a home are the kind of detail that can identify a household when combined with an address. The arithmetic needs none of that, so there is no reason to collect it. If you use the tool on a shared device, closing the tab is enough to remove the values from the page.
Browsers sometimes offer to remember form values as part of their own autofill. That is a browser feature outside this page's control, and it can be cleared in the browser's settings.
What the server sees
Like any website, the server receives the request for the page: URL, time, IP address and user agent. Those requests are used to serve pages and to count aggregate traffic. They do not contain the areas you typed.
Third parties
The pages load no third-party scripts, fonts, images or embeds. There is no advertising network and no analytics service. The only requests are for this site's own stylesheet, script and icons.
Children
Nothing is collected, so there is nothing to collect from a child. The tool is a household budgeting aid, not a service directed at children.
