The short version
Calcaroo is a free calculator and conversion website. You don't need an account, and we don't ask for personal details to use any tool. The numbers you type into our calculators stay in your browser.
What we collect
When you visit Calcaroo, we (and our service providers) may collect basic technical information such as your device type, browser, approximate location (country / region), pages visited, and referring site. This helps us understand which calculators are useful and how to improve them.
Cookies and similar technologies
We use a small number of cookies for essential functionality, analytics, and — where applicable — advertising. You can accept or reject non-essential cookies using the banner shown on your first visit, and you can change your choice at any time by clearing your browser storage.
Advertising
Calcaroo may display ads from third-party networks such as Google AdSense. These partners may use cookies to show ads based on your previous visits to this and other websites. You can opt out of personalised advertising via Google Ad Settings or YourAdChoices.
Analytics
We may use privacy-respecting analytics to count visits and understand which calculators are most helpful. We do not try to identify individual visitors.
Your data, your control
Because Calcaroo doesn't require an account, we don't store personal profiles. If you contact us by email, we'll only use that information to reply. You can request deletion of any message you've sent us at any time.
Children
Calcaroo is a general-purpose utility site and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy from time to time. When we do, we'll update the "Last updated" date at the top of this page.
