Who this policy covers
This Privacy Policy explains how CalculatorPro.co.uk ("this site", "we", "us") collects, uses and protects information when you visit calculatorpro.co.uk. The site is operated by Michaela Watkins, based in the United Kingdom. If you have any questions, see the Contact page.
The calculators themselves collect nothing
The mortgage, percentage and BMI calculators on this site run entirely in your browser using JavaScript. Any figures you enter — loan amounts, income, height, weight, and so on — are processed on your own device only. They are never transmitted to, stored on, or seen by us or any third party. Refreshing or closing the page clears everything you entered.
Cookies and similar technologies
This site uses cookies set by third-party services to understand site traffic and to show advertising. A cookie is a small text file stored on your device. The main cookies used on this site are:
| Service | Purpose | More information |
|---|---|---|
| Google Analytics | Measures site visits and usage in aggregate, so we can see which pages and calculators are useful | How Google uses data |
| Google AdSense | Selects and serves advertising, and may use cookies to personalise the ads you see based on your browsing | How Google uses advertising cookies |
You can control or delete cookies through your browser settings at any time, and you can manage the ad personalisation Google shows you using Google's own tools:
- Google Ads Settings — control or opt out of personalised advertising from Google
- Digital Advertising Alliance opt-out — manage personalised ads from other participating networks
Where required for visitors in the UK and EEA, a cookie consent banner is shown on first visit, allowing you to accept or reject non-essential cookies before they are set.
Google AdSense
This site is a participant in the Google AdSense programme, which uses cookies to serve ads based on a user's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings.
Google Analytics
We use Google Analytics to understand, in aggregate and anonymised form, how visitors use this site — for example which pages are viewed and roughly how long visitors spend on them. This data helps us improve the site. Google Analytics data is not used to identify you personally. You can opt out of Google Analytics tracking across all websites using the Google Analytics Opt-out Browser Add-on.
What we don't do
- We don't require registration or accounts, so we don't hold any login details.
- We don't sell personal data.
- We don't store the figures you enter into any calculator.
Your rights under UK GDPR
If you are in the UK, you have rights under the UK General Data Protection Regulation and the Data Protection Act 2018 in relation to any personal data held about you, including the right to:
- be informed about how your data is used;
- access the personal data we hold about you;
- request correction of inaccurate data;
- request erasure of your data;
- restrict or object to certain processing, including for direct marketing or ad personalisation; and
- data portability, where applicable.
Because this site does not collect or store personal data directly, most of these requests will relate to Google's processing via Analytics and AdSense, which you can manage using the opt-out links above. You can also complain to the UK's data protection regulator, the Information Commissioner's Office (ICO), if you believe your data has been mishandled.
Children's privacy
This site is not directed at children, and we do not knowingly collect data from anyone under 16.
Changes to this policy
We may update this Privacy Policy from time to time, for example to reflect changes in the law or the services we use. The "Last updated" date at the top of this page shows when it was last revised.
