What the site does not collect
There are no contact forms, user accounts, comments, uploads, advertising trackers or analytics scripts on this site. The site does not set cookies and does not use browser local storage.
Calculator inputs
Values entered into a calculator are processed inside the browser tab. They are not sent to this site, saved between visits or used to build a profile. Closing or reloading the page clears the current values unless the browser itself restores a form as part of normal navigation.
Hosting logs
The hosting provider may create ordinary technical request logs containing an IP address, requested URL, browser information and timestamp. The site does not add a separate analytics or tracking layer to those requests.
External links
The sources page contains ordinary links to public guidance and manuals. Following one leaves this site and is governed by the destination's own privacy practices.
If the site changes
If a form, analytics, storage or another data-processing feature is ever added, this page will be updated before that feature is made public.
