Cookie Policy
Effective date: 1 January 2026 | Last reviewed: June 2026
This policy explains what cookies are, which ones we use on the Mainspring website, and the choices available to you. We have tried to keep it practical and plain.
1. What Are Cookies
Cookies are small text files that websites place on your device when you visit. They allow the site to remember your actions or preferences for a period of time, so you don't have to re-enter them every time you return or navigate between pages.
Some cookies are placed by us directly; others are placed by third-party services we use, such as analytics or advertising tools. Cookies set by parties other than Mainspring are referred to as "third-party cookies."
2. How We Use Cookies
We use cookies for four broad purposes:
- Essential operation — to keep the site and contact form working properly.
- Analytics — to understand which pages are visited and how people move through the site, so we can improve it.
- Marketing — to understand whether paid advertising has reached visitors before they arrive on our site.
- Preferences — to remember choices you make, such as your cookie consent decision.

The table below describes the main cookies and storage items active on this site.

4. Your Choices
When you first visit the Mainspring website, a notice is displayed at the bottom of the screen. You can choose to accept or decline non-essential cookies. Your choice is stored in your browser's local storage and applied on subsequent visits.
You may also manage or remove cookies through your browser settings at any time. Below are links to guidance for common browsers:
Please be aware that declining all cookies may affect some aspects of how the site displays or functions, as certain features depend on essential cookies.
5. Third-Party Services
Some cookies on this site are set by third-party providers including Google and Meta. Their use of data collected through those cookies is governed by their own privacy policies, which we encourage you to review:
6. Do Not Track
Some browsers offer a "Do Not Track" setting that sends a signal to websites asking them not to track your activity. There is no consistent standard for how websites should respond to these signals, and at present we do not alter our cookie behaviour in response to them.
7. Changes to This Policy
We may update this Cookie Policy when we add or change the tools we use, or when relevant rules change. When we make meaningful changes, we will update the effective date at the top of this page. We encourage you to review this page from time to time.
