Cookie & Browser Storage Policy

1. Calculator operation

The calculator code does not require a tracking cookie or an account. Calculations run in the current browser page. Server and network infrastructure may use technical measures for security or delivery; these are separate from storing calculation inputs.

2. Optional saved-tool preferences

Pressing a save/bookmark control stores calculator identifiers in local storage under ck-saved-tools. This keeps your preferred tools available on the same browser and device. The stored list contains no calculator values, personal profile or account details.

The list persists until you remove it, clear site data, or your browser deletes it. A blocked local-storage setting may prevent saving, but does not stop the calculations.

3. Advertising technologies

When Google advertising is enabled, Google and its partners may use cookies and similar technologies for ad delivery, measurement, fraud prevention and, where permitted and applicable, personalisation. These services may recognise browser activity across websites.

Where required, advertising consent must be managed through the applicable Google-certified consent platform. A saved-tools preference is not ad consent, and the browser storage button below does not withdraw third-party consent. Use the advertising privacy message or your browser controls where available.

4. Your controls

You can remove saved tools below or use the site-storage and cookie controls in your browser. Clearing saved tools affects this device’s saved calculator list only. If a third-party privacy message is active, its own controls manage the relevant advertising choices.

5. Policy updates

We may update this page when storage practices or enabled providers change. Refer to the effective and last-updated date for this version and contact us with questions.
