Privacy
Discretion is the product.
The Quantum Club is an invitation-only members club; confidentiality is not a feature, it is the premise. This notice explains what thequantumclub.com collects, why, and how you stay in control. Last updated July 2026.
What we collect
When you use Club AI (the concierge chat), we store the questions you type and the answers given, so we can improve the Club. We do not store your IP address in the clear, only a salted, irreversible hash used to prevent abuse. When you submit an application or a partner enquiry, we store what you provide (such as your name, email, and company) to follow up.
To understand how the site is used and to improve it, we also collect privacy-preserving usage analytics: page views, scroll depth, anonymous interaction and error signals, and web-performance measurements. It is cookieless: no tracking cookies, no cross-site tracking, and no advertising profiles. To recognise a returning browser we store one random first-party identifier on your device — it carries no name or contact details, never leaves this site, and clearing your browser's site data removes it. If you later submit an application, that identifier lets us see which pages mattered to you beforehand. Analytics are processed in the EU, in our own first-party store and through two cookieless, EU-hosted analytics providers: Umami Cloud (aggregate page views) and PostHog (product analytics).
Please don't share sensitive personal details in the chat. It is a concierge, not a secure intake form. A dedicated strategist will handle anything confidential privately.
Why we may contact you
If you give us your email through Club AI or a form, we may contact you about membership, a mandate, or your enquiry, on the basis of your request and our legitimate interest in responding. You can opt out at any time.
Who processes your data
We rely on a small set of trusted sub-processors:
How long we keep it
Club AI conversation records are retained for up to 180 days, then deleted. Applications and partner enquiries are kept only as long as needed to serve you, or as the law requires.
Your rights: access, correction, deletion
You may ask us at any time what we hold about you, to correct it, or to delete it. Write to experience@thequantumclub.com and we will action your request. We are based in Amsterdam and handle data in line with the GDPR.
