Privacy Policy

1. Introduction

Calculators Online (“we”, “us”, “our”) operates calculatorsonline.co.uk (the “Site”), providing free online calculators for UK users. This Privacy Policy explains what information we collect, how we use it, and the choices you have.

By using the Site, you agree to the collection and use of information in accordance with this policy. We do not require you to create an account or provide personal information to use any calculator on the Site.

2. Information We Collect

We aim to collect as little personal data as possible. The information we may process includes:

• Calculator inputs: figures you type into a calculator (e.g. salary, weight, distance) are processed in your browser to generate a result. We do not store or link these inputs to you personally.
• Usage data: standard technical data such as your IP address, browser type, device type, pages visited, and time spent on the Site, collected automatically via analytics tools.
• Cookies and similar technologies: small files stored on your device to remember preferences and measure site performance (see Section 4).
• Contact information: if you email us or use a contact form, we collect the details you voluntarily provide, such as your name and email address.

3. How We Use Information

We use the information described above to:

• Operate, maintain, and improve the Site and its calculators;
• Understand how visitors use the Site so we can fix issues and prioritise new tools;
• Respond to enquiries, feedback, or calculator suggestions;
• Detect, prevent, and address technical or security issues;
• Comply with legal obligations.

We do not sell your personal data to third parties.

4. Cookies & Tracking

The Site may use cookies and similar technologies (such as local storage) for the following purposes:

• Essential cookies: required for the Site to function correctly (e.g. remembering your search filters).
• Analytics cookies: help us understand aggregate visitor behaviour (e.g. Google Analytics or a similar service).
• Advertising cookies: if the Site displays advertising, third-party ad networks may set cookies to serve relevant ads and measure performance.

You can control or delete cookies through your browser settings. Blocking some cookies may affect how parts of the Site function.

5. Third-Party Services

We may use third-party services to help run the Site, including hosting providers, analytics providers, and (where applicable) advertising networks. These providers may process data on our behalf under their own privacy policies. We encourage you to review the privacy policies of any third-party service linked from this Site.

6. Data Retention

We retain personal information (such as contact form submissions) only for as long as necessary to fulfil the purpose it was collected for, or as required by law. Aggregated, anonymised analytics data may be retained for longer periods to help us understand long-term trends.

7. Your Rights (UK GDPR)

If you are a UK resident, you have rights under the UK General Data Protection Regulation, including the right to:

• Access the personal data we hold about you;
• Request correction of inaccurate data;
• Request deletion of your data;
• Object to or restrict certain processing;
• Request a copy of your data in a portable format;
• Lodge a complaint with the Information Commissioner’s Office (ICO).

To exercise any of these rights, please contact us using the details in Section 11.

8. Children’s Privacy

The Site is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can remove it.

9. Data Security

We take reasonable technical and organisational measures to protect the information we hold. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
