1. Introduction
This Cookie Policy explains how Gain Function Ltd ("we", "our", or "us") uses cookies and similar technologies on our website (the "Website").
By using the Website, you consent to the use of cookies in accordance with this policy. If you do not agree to our use of cookies, you should adjust your browser settings or discontinue use of the Website.
This policy should be read in conjunction with our Privacy Policy.
2. What Are Cookies?
Cookies are small text files that are placed on your device (computer, smartphone, or tablet) when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.
Cookies can be "session cookies" (temporary, deleted when you close your browser) or "persistent cookies" (remain on your device for a specified period or until manually deleted).
3. Cookies We Use
We use the following categories of cookies on our Website:
3.1 Strictly Necessary Cookies
These cookies are essential for the Website to function properly. They enable core functionality such as security, accessibility, and cookie consent preferences.
Legal basis: These cookies are necessary for legitimate interests in operating the Website and do not require consent.
| Cookie Name | Purpose | Duration |
|---|---|---|
| cookieConsent | Stores your cookie consent preferences | 1 year |
Error Monitoring (Sentry)
We use Sentry for error monitoring and performance tracking. This service helps us identify and fix technical issues to maintain website functionality and security. Sentry is classified as essential because it supports the legitimate operation of the Website rather than tracking user behaviour for marketing purposes.
Data collected: Error messages, stack traces, browser type, device information, and page URL where the error occurred. No personal identifiers are collected unless an error contains user-submitted data.
For more information, see Sentry's Privacy Policy.
3.2 Analytics Cookies
These cookies help us understand how visitors interact with our Website by collecting and reporting information anonymously. We use this data to improve the Website and user experience.
Legal basis: These cookies require your explicit consent before being set.
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| _ga | Google Analytics | Distinguishes unique users | 2 years |
| _ga_* | Google Analytics | Persists session state | 2 years |
| _gid | Google Analytics | Distinguishes users | 24 hours |
Note: Google Analytics is configured with IP anonymisation to protect your privacy.
3.3 Marketing Cookies
We currently do not use marketing or advertising cookies on our Website.
If we introduce marketing cookies in the future, we will update this policy and seek your consent before setting such cookies.
4. Third-Party Cookies
Some cookies on our Website are set by third-party services we use:
Google Analytics
We use Google Analytics to analyse Website usage and improve user experience. Google Analytics uses cookies to collect information about visitor behaviour.

Privacy measures: IP anonymisation enabled, data retention set to 14 months, data sharing with Google disabled.
For more information, see Google's Privacy Policy.
Google Tag Manager
We use Google Tag Manager to manage website tags (including analytics scripts). Tag Manager itself does not set cookies but facilitates the loading of other services.
For more information, see Google's Privacy Policy.
