Data We Collect
WaterIntakeCalc is a static website with no user accounts and no backend database. The calculator runs entirely in your browser: the numbers you enter (weight, sex, exercise, climate) are used to compute your result on your device and are optionally saved in your browser's local storage so your inputs are remembered next visit. This information never leaves your device and you can erase it at any time by clearing your browser's site data for this domain.
