Privacy Policy

For the purposes of the UK GDPR and EU GDPR (where applicable), Calcaroo is the data controller of the personal data described in this Privacy Policy.

If you have questions about this policy or your data, please contact us through the Calcaroo Contact page.

Unlike many online platforms, Calcaroo does not require you to sign up or create a profile.

No Personal Identifiers — We do not collect your name, email address, physical address, or phone number during the normal use of our calculators.

Local Processing (Calculator Inputs) — The numbers and details you enter into our calculators (such as financial figures, health metrics, or DIY dimensions) are processed locally within your web browser (client-side). We do not receive or store these calculator inputs on our servers during normal tool usage.

To maintain website performance, security, and usability, we collect limited non-identifying technical information automatically through our servers and trusted third-party providers.

Log Data — This may include your IP address (anonymized where possible), browser type, operating system, referring URLs, and visit timestamps.

Usage Data — We may collect anonymous usage information to understand which calculators and guides are most useful and how visitors navigate the website.

Approximate Location Data — We may determine your approximate country or city-level location to provide regionally relevant settings such as currency or measurement units.

Calcaroo uses cookies and similar technologies to improve user experience and website functionality.

Essential Cookies — Required for the website to function properly.

Analytics Cookies — Used to understand traffic patterns and improve performance and usability.

Advertising Cookies — Third-party advertising partners, including Google AdSense, may use cookies to display personalised or contextual advertisements based on your browsing behaviour.

Your Choices — You can manage cookie preferences through the consent banner presented when you first visit the site. You may also manage advertising preferences via Google Ad Settings or aboutads.info.

For users located in the United Kingdom or European Economic Area (EEA), we process information under the following legal bases:

Legitimate Interests — To maintain website security, prevent abuse, understand site usage, and improve our services.

Consent — For non-essential cookies, analytics tracking, and personalised advertising where legally required.

Calcaroo may link to third-party websites including banks, lenders, government services, analytics providers, or advertising partners.

We do not control these third-party services and are not responsible for their content, policies, or practices. We encourage users to review their privacy policies separately.

We use reasonable technical and organisational measures to protect the limited information we collect.

Because Calcaroo does not store calculator inputs or personal user profiles during normal usage, the risk of personal data exposure is significantly reduced.

Technical logs and analytics data are retained only as long as reasonably necessary for security, analytics, and operational purposes.

Depending on your location, you may have rights under applicable data protection laws, including:

• Right of access
• Right to rectification
• Right to erasure
• Right to restrict processing
• Right to object
• Right to data portability
• Right to withdraw consent

As Calcaroo generally does not collect directly identifiable personal information during normal use, we may not always be able to identify individual users from technical usage data alone.

If you contact us directly, you may request access to or deletion of correspondence associated with your communication.

UK users also have the right to lodge a complaint with the Information Commissioner’s Office (ICO): https://www.ico.org.uk.

Some third-party services used by Calcaroo, including analytics and advertising providers, may process data outside the United Kingdom or European Economic Area.

Where applicable, these providers are expected to use appropriate safeguards and data protection mechanisms.

Calcaroo is a general-purpose utility website and is not directed at children under the age of 13 (or 16 where applicable by local law).

We do not knowingly collect personal information from children.

We may update this Privacy Policy periodically to reflect operational, legal, or regulatory changes. Any significant updates will be reflected by updating the “Last Updated” date at the top of this page.

If you have questions about this Privacy Policy or how your information is handled, please contact us through the Calcaroo Contact page.
