Seventy3 OS — Cookie Policy
Seventy3 Group Ltd Effective date: 13 July 2026 · Last updated: 13 July 2026 · Version 1.0
This Cookie Policy explains how Seventy3 Group Ltd ("Seventy3", "we", "us") uses cookies and similar technologies on our website and platform. It should be read alongside our Privacy Policy. It is provided in accordance with the Privacy and Electronic Communications Regulations (PECR) and UK GDPR.
1. What cookies are
Cookies are small text files placed on your device when you visit a website. Similar technologies (such as local storage, pixels, and SDKs) work in comparable ways. They let a site remember your actions and preferences, keep you signed in, and understand how the site is used.
2. How we use cookies
We use cookies to:
- keep you securely signed in and maintain your session;
- remember your preferences and settings;
- keep the site and platform secure and detect misuse;
- understand how our website is used so we can improve it (analytics);
- (only with your consent) measure the effectiveness of our marketing.
3. The categories of cookies we use
3.1 Strictly necessary cookies — always on
These are essential for the website and platform to function (for example, authentication, session management, security, and load balancing). They do not require consent because the service cannot be provided without them. You can set your browser to block them, but parts of the site will not work.
3.2 Analytics cookies — consent required
These help us understand how visitors use our website (pages visited, time on page, general location, device type) so we can improve it. They are set only if you accept them via our cookie banner. Analytics data is aggregated and, where identifiable, retained for no longer than 13 months.
3.3 Marketing cookies — consent required
These may be used to measure and improve the performance of our marketing and, where applicable, to show relevant content. They are set only with your consent.

5. Managing your preferences
- Cookie banner. When you first visit, our banner lets you accept or reject non-essential cookies. Strictly necessary cookies are set by default; analytics and marketing cookies are set only if you accept.
- Change your mind at any time. You can revisit your preferences via the "Cookie preferences" link in our website footer.
- Browser controls. Most browsers let you block or delete cookies. See your browser's help pages. Blocking strictly necessary cookies may stop parts of the service working.
6. Third-party cookies and international transfers
Some analytics or marketing tools we may use are operated by third parties who may process data outside the UK. Where that happens, we rely on an appropriate transfer mechanism (UK IDTA / EU SCCs + UK Addendum) as described in Section 7 of our Privacy Policy. We only enable such tools with your consent.
7. Changes to this Policy
We may update this Cookie Policy from time to time. The current version is always available on our website with the date last updated.
