This Cookie Policy explains what cookies and similar tracking technologies are used in connection with the Buff CRM Platform, operated by DASE Systems Limited, and how you can control them.
This policy should be read alongside our Privacy Policy, which provides further information about how we handle your personal data more broadly.
If you have any questions about our use of cookies, please contact us at [email protected].
Cookies are small text files that are placed on your device when you visit a website or use a web application. They are widely used to make websites and applications function correctly, to improve efficiency, and to provide information to the operators of those sites.
Session cookies — temporary cookies deleted when you close your browser or end your session. Used to keep you logged in during a single visit.
Persistent cookies — cookies that remain on your device for a set period of time even after you close your browser. Used to remember your preferences across multiple visits.
First-party cookies — cookies set directly by DASE.
Third-party cookies — cookies set by a domain other than the website you are visiting, typically by third-party services the site uses.
We may also use similar technologies such as local storage, session storage, and pixels. Where this policy refers to "cookies", it includes all such technologies unless the context otherwise requires.
This section covers cookies used within the Buff CRM application at app.buffcrm.co.uk.
Strictly necessary cookies are essential for the Platform to function. These do not require your consent under PECR because they are strictly necessary for a service you have requested.

We use analytics tools on the marketing site to understand how visitors find and navigate the site. We are committed to privacy-friendly analytics. We will seek your consent before placing any non-essential analytics cookies.
When you arrive via a referral or affiliate link, we set a short-lived session storage entry to preserve attribution parameters through to signup. This is stored in your browser's session storage, not as a cookie, and is transmitted to us only when you complete the signup process.
We may in future introduce additional cookies on the marketing site. We will update this Cookie Policy before introducing any new cookie categories and will seek your consent for any non-essential cookies before placing them.
When you first visit the Buff CRM marketing site or the application, you will be presented with a cookie consent banner. You can change your preferences at any time using the cookie settings link in the footer.
You can control cookies through your browser settings. Guidance for common browsers:
Where your browser sends a Do Not Track signal, we will honour that preference and will not set optional analytics or functional cookies.
Cloudflare cookies are governed by Cloudflare's own privacy policy at cloudflare.com/privacypolicy.
Where cookies involve the processing of personal data, that processing is governed by our Privacy Policy. Cookies that do not involve personal data are still governed by the Privacy and Electronic Communications Regulations 2003 (PECR).
We may update this Cookie Policy from time to time. We will notify existing Subscribers of material changes via the Platform or by email. Previous versions are available on request by emailing [email protected].
