This policy explains what personal data Poundsum collects, why, and your rights under UK data protection law (the UK GDPR and the Data Protection Act 2018). Last updated: 5 November 2026.
Who we are
Poundsum is the controller of personal data collected through this website. You can contact us at contact@poundsum.co.uk.
Information you type into calculators
Our calculators run entirely in your web browser. The figures you enter, such as your salary or mortgage balance, are not sent to us and are not stored on our servers.
Information we collect
- Emails you send us: your email address and message, used only to reply to you.
- Technical data: like most websites, our hosting provider records basic server logs (IP address, browser type and pages visited) to keep the site secure and working.
- Analytics: if you agree to analytics cookies, we use Google Analytics to understand how visitors use the site, for example which pages are popular. This data is aggregated and does not identify you directly.
- Advertising: if you agree to advertising cookies, Google and its partners may use cookies to show ads (see below).
Cookies and consent
When you first visit, a consent message lets you accept or refuse non-essential cookies. You can change your choice at any time using the cookie settings link in the footer. Essential cookies needed for the site to work do not require consent.
Advertising
We use Google AdSense to show ads, which helps keep the site free. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet.
You can opt out of personalised advertising in Google Ads Settings, and learn more about how Google uses data at How Google uses information from sites that use its services.
Legal basis
We rely on your consent for analytics and advertising cookies, and on our legitimate interests to reply to your messages and keep the site secure.
How long we keep data
We keep emails for up to two years unless we need them longer to deal with a query. Analytics data is kept for 14 months. Server logs are kept by our host for a short period for security.
Your rights
You have the right to ask for a copy of your data, to have it corrected or deleted, to object to or restrict how we use it, and to withdraw consent at any time. Email us to make a request; we will reply within one month.
If you are unhappy with how we handle your data, you can complain to the Information Commissioner’s Office (ICO).
