Privacy & data protection.
How GBX Circle Ltd collects, holds and protects the personal data entrusted to the Circle — held to the same discretion as the room itself.
Last updated · February 2027
1 · Who we are
GBX Circle Ltd ("GBX", "the Circle", "we") is the data controller for personal data processed through this forum and its related sites. We are registered in England & Wales (Co. No. 16685118), with a registered office at 80 Strand, London WC2R 0RL. For any question about this notice or your data, contact hello@gbxcircle.com.
2 · What we collect
We collect only what the conversation requires:
- Identity & contact — name, organisation, job title, email and telephone number, provided when you request access or correspond with us.
- Curation detail — the priorities, challenges and interests you share so we can assess relevance to the room.
- Technical data — anonymised analytics (pages viewed, approximate region, device) gathered to understand how the site is used.
3 · How we use it
- To assess and administer requests for access to Circle forums.
- To curate the room — matching participants by relevance and seniority.
- To communicate with you about the forum you have expressed interest in.
- To meet our legal, accounting and reporting obligations.
4 · Lawful basis
We rely on legitimate interests (convening a relevant, senior audience), consent (where you opt in to the Signal or other updates — withdrawable at any time), and legal obligation where the law requires us to retain records.
5 · Who sees it
Your data is treated with the discretion of the room. We do not sell it. We share it only with trusted service providers acting on our instructions (for example, secure hosting, form processing and email delivery), each bound by contract to protect it, and only where the law requires.
6 · How long we keep it
We retain personal data only as long as necessary for the purpose it was collected, and thereafter as required for legal and accounting obligations. When it is no longer needed, it is securely deleted.
7 · Your rights
Under UK GDPR you may request access to, correction of, or erasure of your personal data; object to or restrict its processing; and withdraw consent at any time. To exercise any right, write to hello@gbxcircle.com. You also have the right to complain to the Information Commissioner's Office (ico.org.uk).
8 · Cookies & analytics
We use privacy-respecting analytics to understand site usage in aggregate. These do not identify you personally. You can control cookies through your browser settings.
