Calculations happen on your device
Heights, waist measurements, formula selections and optional comparison names are processed in your browser. This version does not submit them to a server, put them in page URLs or save them to cookies or local storage. Refreshing the page clears the inputs.
The light/dark theme choice is saved locally as a preference. It contains no body measurements or names. Language is selected by page URL, with English as the default.
No analytics in this version
We have not installed Google Analytics, advertising scripts or other third-party tracking. There are no accounts, payments or database records. If analytics are added later, this notice must be updated; body measurements, names and complete form values must not be sent as analytics events.
Downloaded images
Height comparison PNGs are generated locally. They contain the displayed names and heights, and are saved where your browser downloads files. You decide whether to share them.
Ordinary web requests
Loading any hosted website sends technical request information, such as IP address, requested path, browser information and time, to the hosting provider. Hosting access logs and retention depend on the eventual deployment settings. They are separate from calculator inputs. This local version does not configure a hosting service.
External sources
Source links open external sites governed by their own privacy policies. No external fonts or media are needed for our tools.
Future changes
Changes to data handling will be reflected here before those features are released. There is no contact address published in this initial version.
