Cookie Policy
Last updated: 16 April 2026
What are cookies?
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work, or to work more efficiently, and to provide information to the site owner.
Cookies we use
We use two categories of cookies: strictly necessary cookies (which do not require consent) and optional analytics cookies (which require your consent before being set).
| Cookie name | Category | Purpose | Duration |
|---|---|---|---|
sc_cookie_consent |
Required | Stores your cookie consent preference so we do not ask again on every visit. | 12 months |
Analytics cookies (e.g. _ga) |
Optional | Anonymous analytics to understand how pages are used — number of visitors, pages viewed, referral source. No personal data is collected or individual users identified. | Up to 26 months |
Strictly necessary cookies
Strictly necessary cookies are essential for the website to function. They do not collect any personal information and do not require your consent under UK PECR (Privacy and Electronic Communications Regulations). You cannot opt out of these cookies without affecting the functioning of the site.
Optional analytics cookies
We use anonymous analytics to understand how visitors use the site. This helps us improve the calculators and content. Analytics cookies are only set if you have consented. The data collected is aggregated and anonymised — no individual user profiles are created, and no data is shared with advertising networks.
You can withdraw your consent to analytics cookies at any time by clearing your cookies in your browser settings. You can also opt out of Google Analytics across all sites by installing the Google Analytics Opt-out Browser Add-on.
Cookies we do not use
We do not use:
- Advertising or targeting cookies
- Social media tracking cookies
- Cookies that identify you as an individual
- Third-party cookies (other than Google Analytics when consented)
How to manage cookies
Most web browsers allow you to control cookies through their settings. You can set your browser to refuse cookies, delete existing cookies, or notify you when a cookie is being set. Note that refusing strictly necessary cookies may affect the functionality of the site.
