About This Policy
This Cookie Policy explains how Cairnstone Capital Limited ("we", "us", or "our") uses cookies and similar technologies on our platform. This policy complies with the Privacy and Electronic Communications Regulations 2003 (PECR) and the UK General Data Protection Regulation (UK GDPR).
What Are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently and to provide information to the website owners.
Cookies We Use
We use only strictly necessary cookies that are essential for the operation of our platform. We do not use any tracking, analytics, or advertising cookies.

| sb-*-auth-token-code-verifier | PKCE code verifier for secure authentication flow | Session |

Why These Cookies Are Necessary
Our authentication cookies are strictly necessary for the following reasons:

- Session Management: They keep you signed in as you navigate between pages, so you don't have to log in repeatedly
- PKCE Protection: They implement Proof Key for Code Exchange (PKCE), an industry-standard security mechanism that protects against authorization code interception attacks
Under PECR, strictly necessary cookies do not require consent as they are essential for the service you have requested. However, we still inform you about their use for transparency.
No Tracking or Analytics Cookies
We want to be clear: we do not use any tracking, analytics, or advertising cookies. Your browsing activity on our platform is not monitored for marketing purposes, and we do not share any cookie data with third parties for advertising.
