Cookie Policy
Last updated: June 12, 2026
This Cookie Policy explains how Online Calculator.tools uses cookies and similar browser storage technologies, and the choices available to you.
01What are cookies?
Cookies are small text files stored on your device by your browser. Similar technologies, such as local storage, let a site remember information between visits. We use a minimal set of these to make the site work and to remember your preferences.
02How we use them
We keep our use of cookies and storage deliberately small:
- Preferences: we store your light/dark theme choice in your browser's local storage so the site remembers it.
- Analytics: we may use privacy-respecting analytics cookies to measure aggregate, anonymised traffic and improve the site.
- Essential: some storage may be required for core functionality and security.
03Categories of cookies
Essential cookies are necessary for the site to function and cannot be switched off in our systems. Preference cookies remember choices like your theme. Analytics cookies help us understand how visitors use the site in aggregate.
04Managing your preferences
You can control and delete cookies and local storage through your browser settings. Blocking some types may affect how the site works — for example, your theme preference may not be remembered between visits.
05Changes to this policy
We may update this Cookie Policy as our practices evolve. The date at the top of this page shows when it was last revised.
