Privacy Policy

Last updated 30 September 2026

In short

The trades you paste in or import, and the savings you enter, stay in your own browser. They are never sent to us or stored on our servers. We use Vercel Web Analytics to count visits and a few actions, such as importing a file. It uses no cookies and never sees your trades or figures. We don't use advertising trackers, and you don't need an account. Some guides have a video hosted on YouTube, and nothing is loaded from YouTube unless you press play.

Who we are

This policy covers ukcapitalgains.com ("UK Capital Gains Tax Calculator", "we", "us"). You can contact us at hello@ukcapitalgains.com.

The trades and figures you enter

All calculations happen in your web browser, on your own device. The trades, prices, income and other figures you enter are not sent to us, and we can't see them. If you import a file from your broker, it is read on your device and is never uploaded.

So that your trades are still there when you come back, your browser saves them in its local storage on your device. You can remove them at any time by clicking "Reset example" on the calculator, or by clearing your browser's data for this site.

The savings calculator works the same way. The amounts, rates, tax band, dates and spending you enter stay on your device and are never sent to us. Your plan is saved in your browser's local storage so it's there when you come back. You can remove it by clicking "Start again" on the savings calculator, or by clearing your browser's data for this site.

Cookies and tracking

We don't use cookies, and we don't use advertising or social media trackers. YouTube may set cookies if you play a guide's video: see "Videos on guides" below. A broker, or an affiliate network, may set cookies once you follow a link to its site: see "Links to brokers" below.

We use Vercel Web Analytics to understand how the site is used. It counts the pages people visit and a small set of actions, such as importing a file from a broker, changing the tax year, seeing a result, adding and comparing savings in the savings calculator, playing a guide's video, or following a link to a broker. With each one it records the page, the site you came from, your country, and your browser, operating system and device type. For imports, it records which broker the file came from and roughly how many trades it had, such as "11 to 50". For the savings calculator, it records only the type of savings, such as "fixed-rate account", and roughly how many holdings a plan has. For a link to a broker, it records only which broker and which page the link was on.

Analytics never receives the trades, prices, amounts, rates, dates or other figures you enter, or the names of the files you import. It doesn't use cookies or store anything on your device. Visits are grouped using a short-lived code that Vercel discards after 24 hours, so we can't identify you or follow you across other websites. We only see totals. You can read more in Vercel's Web Analytics privacy information.

Apart from guide videos, described below, we don't load content from other third-party services. If this changes, we'll update this policy first.

Videos on guides

Some guides have a short explainer video hosted on YouTube, which is run by Google. Until you press play, the guide shows our own image of the video, and nothing is loaded from YouTube or Google.

When you press play, the video loads from YouTube in its privacy-enhanced mode (youtube-nocookie.com). YouTube then receives your IP address and information about your browser and device, and it may store cookies or similar information on your device, for example to remember your settings or measure how the video is watched. Google handles this information under Google's privacy policy, and may process it outside the UK. If you'd rather not share this with Google, don't play the video. The guide covers everything the video does.

Links to brokers

Our broker comparison and some guides link to brokers' websites. Some of these links may be affiliate links: if you open an account through one, the broker may pay us a commission. Each affiliate link is labelled next to it.

We don't load any affiliate or advertising scripts, and following a link sets nothing on our site. The link takes you straight to the broker, or to an affiliate network that passes you on to the broker. Once you're there, the broker or the network may set cookies and record your visit, so that the broker knows we referred you. They handle that information under their own privacy policies, not ours.

Our hosting provider

The site is hosted by Vercel Inc. Like any website host, Vercel automatically records basic technical information when you visit, such as your IP address, browser type and the pages you request. This is used to deliver the site and keep it secure, and it is kept only for a short period.

Vercel may process this information outside the UK, including in the United States. Where it does, it uses the safeguards required by UK data protection law. You can read Vercel's privacy policy.

If you email us

If you contact us, we'll use your email address and message only to reply to you. We'll keep them only as long as we need to deal with your message, and we won't add you to a mailing list or share your details.

Your rights

Under UK data protection law you have the right to ask what personal information we hold about you, and to ask us to correct or delete it. Because we don't collect your trades, the only personal information we're likely to hold is an email you've sent us.

If you're unhappy with how we handle your information, please contact us first. You can also complain to the Information Commissioner's Office (ICO).

Changes to this policy

If we change how we handle information, we'll update this page and the date at the top.
