This privacy policy explains how My Stamp Duty ("we", "us", "our") collects, uses, and protects information when you use our website at my-stamp-duty.co.uk.
All stamp duty calculations are performed locally in your web browser. The information you enter (property prices, buyer type) is:
We do not collect, store, or have access to any property price information or calculation data you enter.
We do not use any analytics or measurement service on this site. No tag or script records the pages you visit, how long you stay, or where you came from.
The only non-essential cookies on the site are the advertising cookies described below, and they are set only if you agree to them.
This site does not use cookies or local storage. All calculations are performed in real-time without saving any data.
Our site may use third-party cookies from one service only:
Google may use those cookies to choose the advertisements you see and to measure how they perform. You can control cookie preferences through your browser settings.
We use Google AdSense to display advertisements on our site. Google and its partners may use cookies and other tracking technologies to:
You can opt out of personalised advertising by visiting Google's Ads Settings or www.youronlinechoices.com.
Since we do not collect or store personal information or calculation data on our servers, there is minimal data security risk. All calculations occur in your browser and no data leaves your device.
Under UK data protection law (UK GDPR), you have the right to:
This calculator provides estimates based on current HMRC stamp duty rates. It is not financial or legal advice. The calculations are for informational purposes only. Always consult with a qualified solicitor, conveyancer, or tax advisor for advice specific to your property purchase.
We strive to ensure our calculator uses accurate and up-to-date stamp duty rates. However, tax legislation can change. We are not responsible for any financial decisions made based on calculations from this tool. Always verify stamp duty amounts with HMRC or your solicitor before completing a property purchase.
Our site may contain links to external websites (such as gov.uk and HMRC). We are not responsible for the privacy practices of external sites. Please review their privacy policies separately.
We retain data as follows:
Since we do not collect personal data directly, there is no personal data for us to delete from our servers.
We may update this privacy policy from time to time. The "Last updated" date at the top will reflect any changes. Continued use of the site after changes indicates acceptance of the updated policy.

Measurement cookies, which count visits so we can see which pages are worth keeping, are only set if you agree to them. When you first visit you are asked, and nothing is stored until you answer. Declining is a single click on the same footing as accepting.
Advertising cookies are a separate question, asked separately by Google's own certified notice rather than by us. Google is the advertising partner, the cookies are set by Google, and only its notice is certified to record that choice and pass it on, so we do not ask on its behalf.
You can change your mind at any time using the Cookie settings link in the footer of any page. Your measurement choice is kept in your browser's own local storage, on your device: it is never sent to us and is not used to identify you.
Cookies already set by an earlier choice can be cleared through your browser settings.
