Privacy Policy

Calculation processing. The calculator processes inputs and results in your browser rather than submitting them to a calculation service. Browser history storage is optional, as described below.

History. Recent calculations are kept in memory and cleared when you close or reload the page. If you tick “Save history on this device”, up to 20 recent entries are stored in your browser's localStorage. Untick the option or clear history to delete them.

Preferences. Your light or dark theme choice is saved in localStorage.

Analytics. Lovable analytics is enabled for this website to report visits and page views. This is separate from the calculator's local arithmetic. This policy does not claim that website visits are untracked.

Hosting and fonts. Loading pages creates requests to the hosting service. Web fonts are loaded from Google Fonts, so your browser also contacts Google. These requests are separate from local calculation processing.
