Privacy Policy
How UK Calculator Ltd collects, uses and protects your personal data
1. Introduction
UK Calculator Ltd (“we”, “us”, “our”) operates the website https://ukcalculator.com (the “Service”). We are registered in England and Wales under company number 15847293, with our registered address at 128 City Road, London, EC1V 2NX.
This Privacy Policy explains what information we collect when you visit our website, how we use that information, and your rights in relation to it. We are committed to protecting your privacy and handling any personal data we obtain with care, transparency and respect for your rights.
This policy applies to all information collected through our website and any related services, communications or content. It was last reviewed and updated on 1 February 2026.
We act as the data controller for personal data processed in connection with this website. Our processing is carried out in accordance with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.
By using our website, you acknowledge you have read and understood this Privacy Policy. If you do not agree with our practices, please do not use our website.
2. Data We Collect
UK Calculator provides free online calculators. We do not require users to create an account, register, or provide any personal information to use any of our calculators. No personal data is submitted through our calculator tools — all calculations happen locally in your browser.
We do, however, collect certain usage data automatically when you visit our website, including:
- IP address (anonymised before storage — see Google Analytics section below)
- Browser type and version (e.g. Chrome 120, Safari 17)
- Operating system (e.g. Windows 11, macOS, Android)
- Pages visited and time spent on each page
- Referring website (the site that directed you to us)
- Date and time of your visit
- General geographic location (country/region level, derived from anonymised IP)
This data is collected via Google Analytics (described below) and is used solely to understand how our website is used so we can improve it. We do not use this data to identify individual users.
No sensitive data collected. We do not collect names, email addresses, financial details, health data, or any other personally identifying information through our calculators or any other part of our website (other than if you voluntarily contact us via email).
If you contact us by email at [email protected] or [email protected], we will receive and store your email address and any personal information you choose to include in your message. We use this solely to respond to your enquiry.
The legal basis for processing usage data is legitimate interests (Article 6(1)(f) UK GDPR) — specifically, our interest in understanding how our website is used in order to improve it. Where you have given consent via our cookie banner, the legal basis is consent (Article 6(1)(a) UK GDPR).
3. Google Analytics
We use Google Analytics 4 (GA4), a web analytics service provided by Google LLC (“Google”). Google Analytics uses cookies and similar technologies to collect and analyse information about the use of our website and to report on website activities and internet usage.
We have implemented Google Consent Mode v2 on our website. This means:
- Analytics tracking is disabled by default when you first visit our website
- Full analytics data collection only begins if you accept analytics cookies via our cookie consent banner
- If you decline or do not interact with the consent banner, Google operates in a limited (cookieless) modelling mode
When Google Analytics is active, it may collect the following information:
- Pages visited and navigation paths through the site
- Time spent on pages and overall sessions
- Events such as button clicks and calculator interactions
- Device type, browser and operating system
- Approximate geographic location (country/city level)
We have enabled IP anonymisation in Google Analytics. Your IP address is truncated before any geographic analysis, and the full IP address is never stored by Google on our behalf.
We have set the data retention period in Google Analytics to 14 months. Google Analytics data is processed by Google on servers which may be located outside the UK. Google participates in the EU-US Data Privacy Framework and provides appropriate safeguards for international transfers.
For more information about how Google uses data when you use our site, please visit: policies.google.com/privacy. To opt out of Google Analytics across all websites, you can install the Google Analytics Opt-Out Browser Add-on.
4. Google AdSense
We display advertising on our website provided by Google AdSense, operated by Google LLC. Advertising revenue allows us to provide our calculators free of charge to all users.
Google AdSense uses cookies and web beacons to show you advertisements. Google may use the data it collects to personalise the ads you see, based on your interests and your browsing history across websites that use Google advertising services.
We have enabled Google Consent Mode v2 which means:
- Personalised advertising is only served if you have consented to advertising cookies via our consent banner
- If you decline advertising consent, you may still see ads, but they will be non-personalised (contextual only)
Our Google AdSense publisher ID is ca-pub-2828507912890700.
You can opt out of personalised advertising from Google at any time by visiting adssettings.google.com. You can also opt out of interest-based advertising from other participating companies via the Your Online Choices tool.
For more information about how Google uses data in connection with advertising, please visit: policies.google.com/technologies/ads.

We use the following categories of cookies:

6. Your Rights under UK GDPR
Under the UK General Data Protection Regulation and the Data Protection Act 2018, you have a number of rights in relation to your personal data. These rights are summarised below:
Right of Access
You have the right to request a copy of the personal data we hold about you (commonly known as a “Subject Access Request”).
Right to Rectification
You have the right to request that we correct any inaccurate or incomplete personal data we hold about you.
Right to Erasure
You have the right to request deletion of your personal data in certain circumstances (the “right to be forgotten”).
Right to Restriction
You have the right to request that we restrict the processing of your personal data in certain circumstances.
Right to Portability
Where processing is based on your consent or a contract, you have the right to receive your data in a structured, machine-readable format.
Right to Object
You have the right to object to processing of your personal data where we rely on legitimate interests as our legal basis.
Right to Withdraw Consent
Where processing is based on your consent, you may withdraw that consent at any time without affecting the lawfulness of prior processing.
Right to Complain
You have the right to lodge a complaint with the UK’s supervisory authority, the Information Commissioner’s Office (ICO), at ico.org.uk.
To exercise any of these rights, please contact us at [email protected]. We will respond to all requests within one calendar month. We may need to verify your identity before processing your request.
Please note that because we collect very limited personal data (primarily anonymised analytics data), some of these rights may have limited practical application in the context of our website.
7. Data Retention
We retain personal data only for as long as necessary to fulfil the purposes for which it was collected and to comply with our legal obligations.
- Google Analytics data: We have set the retention period to 14 months, after which data is automatically deleted from Google’s servers.
- Email correspondence: If you contact us by email, we retain your correspondence for up to 2 years in case of follow-up enquiries, after which it is deleted.
- Cookie consent records: Your consent preferences are stored in a cookie on your device for up to 2 years.
We do not store any other personal data on our own servers. We do not run a user database, and no personal information entered into our calculators is ever transmitted to or stored on our servers.
8. Third Party Links
Our website contains links to external websites, including official government and regulatory sources such as HMRC, GOV.UK, the NHS, the Office for National Statistics (ONS), and other reputable organisations. We link to these sources to provide accurate, up-to-date information for our users.
We are not responsible for the privacy practices or content of these external websites. We encourage you to review the privacy policy of any external site you visit. Once you leave our website, this Privacy Policy no longer applies.
External links are clearly marked and open in a new browser tab where appropriate. We do not have any control over and are not liable for the content or privacy practices of any third party website.
9. Children’s Privacy
Our website is not directed at children under the age of 13. We do not knowingly collect personal data from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at [email protected] and we will delete such information promptly.
While some of our calculators (such as BMI calculators for children) are designed to be useful for parents calculating metrics for their children, the service itself is intended to be used by adults or under adult supervision.
10. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements or other factors. When we make significant changes, we will update the “Last updated” date at the top of this page.
We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information. Your continued use of our website after any changes to this Privacy Policy constitutes your acceptance of the revised policy.
If we make any material changes that significantly affect your rights or how we use your data, we will make reasonable efforts to notify you, such as by displaying a prominent notice on our website.
