This page explains what cookies are, which cookies StampDutys.com and its advertising partners (including Google AdSense) may use, and how you can control, delete or opt out of them.
Cookies are small text files that a website can place on your computer, phone or tablet when you visit it. They let a site (or a third party the site works with, such as an advertising network) recognise your browser on later visits, remember simple choices you've made, or collect information about how a device is used across the web. A cookie on its own usually isn't enough to identify you by name, but it can be used to recognise the same browser over time.
Similar technologies — such as local storage, pixels and tags — can do comparable jobs to cookies. For simplicity, this policy refers to all of these collectively as "cookies".
Most of the interactivity on StampDutys.com — including every calculator on this site — runs entirely client-side in your browser using JavaScript. The calculators read what you type, do the maths, and show you the result without sending your inputs to a server or needing a cookie to function. In plain terms: you can use the calculators with cookies switched off entirely and they will still work.
Where this site does use its own ("first-party") cookies, they are limited to strictly necessary or functional purposes — for example, remembering that you've closed the mobile navigation menu, or basic settings that make the site easier to use on a repeat visit. These cookies don't track you across other websites and aren't used to build an advertising profile.
StampDutys.com displays advertising served through Google AdSense. To serve ads, measure how they perform, and limit how often you see the same ad, Google and its advertising partners may set third-party cookies in your browser — for example, cookies associated with doubleclick.net or other Google ad-serving domains, including the cookie commonly used for ad personalization and conversion measurement across Google's ad network (sometimes referred to as the "DoubleClick"/Google Ads cookie).
Depending on your location and the consent choices you make, these cookies may be used to show you ads based on your general browsing activity across sites that use Google's advertising products, rather than ads chosen purely at random. Google's own policy on how it uses cookies for advertising, and the specific cookies and technologies involved, is explained on Google's "How Google uses cookies in advertising" page.
If and when we add a usage-analytics tool to this site — for example, Google Analytics — it would use its own cookies to tell us, in aggregate, things like how many people visited a page, which calculators are most used, and roughly where visitors are browsing from, so we can improve the site. We do not currently combine analytics data with anything that identifies you personally. If this changes, this policy will be updated to reflect it.
The table below is a general, illustrative guide to the categories of cookies a site like this may encounter — it is not a guarantee that every category is active at all times, and exact cookie names can change as Google and other providers update their systems.
| Category | Set by | Purpose | Typical duration |
|---|---|---|---|
| Strictly necessary / functional | StampDutys.com (first-party) | Remembering menu state and basic interface preferences | Session, up to a few months |
| Advertising | Google AdSense / doubleclick.net and ad-tech partners | Serving ads, frequency capping, and personalizing ads based on browsing activity | Typically up to 13 months, some shorter |
| Ad measurement | Google and advertising partners | Measuring ad clicks and conversions, fraud prevention | Typically 30 days to a few months |
| Analytics (if enabled) | Google Analytics or similar | Aggregate, non-identifying usage statistics | Typically up to 13–26 months |
You can allow, block or delete cookies at any time through your browser's settings. Broadly:
Blocking all cookies may stop some parts of some websites from working, though as noted above, this site's own calculators will still function without cookies.
To opt out of personalized advertising from Google specifically, visit Google's Ad Settings page. To opt out of interest-based advertising from many participating companies at once, visit the Digital Advertising Alliance's consumer choice tool at www.aboutads.info/choices. Opt-outs set this way are themselves stored as cookies in your browser, so they may need to be re-set if you clear your cookies or switch browsers/devices.
Some browsers offer a "Do Not Track" (DNT) setting that asks sites not to track you. Being honest about it: there is no single, universally agreed standard for how websites should respond to DNT signals, and browser support for the feature is inconsistent — many major browsers and ad networks, including Google's advertising products, do not currently act on DNT signals in a consistent way. For that reason, this site does not currently respond differently based on a DNT signal; use the browser and opt-out controls described above instead for a more reliable result.
Cookies set by Google AdSense, any analytics tool, or other advertising partners are controlled by those third parties, not by StampDutys.com directly — we don't have access to, and can't directly manage, the cookies they set in your browser. For details on how Google specifically uses cookies across its advertising products, see Google's advertising technologies policy.
We may update this Cookie Policy from time to time — for example, if we add a new analytics tool, change advertising providers, or if the law around cookies and tracking changes. Any updates will be posted on this page. This policy was last updated on 12 November 2026.
This Cookie Policy covers cookies and similar tracking technologies specifically. For the fuller picture of what data we collect, why, and your rights over it, see our Privacy Policy.
