Calculator Suite

Privacy

Calculator inputs and results are processed in your browser. Calculator Suite does not send those values to its server and does not include advertising or analytics scripts.

Local preferences

The site uses browser local storage to remember your theme, last-used calculator, recent scientific calculations, recent games, favourites, and a short-lived cache of currency reference rates. These values stay on your device and can be removed using the in-app history controls or your browser’s site-data controls.

Currency requests

When you use the currency converter, the selected currency pair is requested from the keyless Frankfurter reference-rate API. The amount you enter is not included in that request.

Access session

If the optional game area is enabled by the site operator, a secure, HTTP-only session cookie is used to protect it. The cookie contains no calculator values and expires automatically.

External game content

Games are isolated in restricted frames where practical. Individual legacy games may store their own progress locally or load required assets from their original content providers.
