Privacy

Last updated 8 November 2026

This page explains what the membook waitlist collects, why, and how to have it changed or removed. It follows the Stag.ai privacy policy, narrowed to what this site actually does.

1. Who we are

membook is run by Stag.ai Ltd, a private limited company registered in England and Wales, company number 15031121. Registered office: 167–169 Great Portland Street, 5th Floor, London W1W 5PF.

Stag.ai Ltd is the data controller for the waitlist: we decide what’s collected and what it’s used for.

2. What we collect

When you join the waitlist we store:

• your email address
• the line about what you could write about, if you gave one
• the date you joined, and the link that sent you here if it had a tag on it

To stop the form being abused we also keep a one-way hash of your IP address for a day. We can’t turn it back into your IP address.

3. Why we collect it

To invite you when it’s your turn, and to choose who to invite first. We read the lines people leave; that’s how we pick the first writers. We don’t send newsletters, and we do not sell or monetise the list or share it with anyone else.

We send at most two emails: one confirming you’re on the list, and your invite when it’s your turn. Each has a link that removes you straight away.

4. Analytics and cookies

This site sets no cookies and runs no trackers or analytics scripts, so there’s nothing to opt out of. (The wider Stag.ai policy describes telemetry and performance cookies on other Stag.ai services; none of that runs here.)

5. Third-party services

The site and the waitlist are hosted on Microsoft Azure, in the UK and EU, and our emails are sent through Azure Communication Services, with data kept in the UK. Microsoft runs these for us and doesn’t use the data for anything of its own. Emails carry no tracking pixels or tracked links. No other service receives your details.

6. Data retention

We keep your entry while you’re on the waitlist. When membook opens and you’ve had your invite, or when you ask us to remove you, we delete it. You can ask for that at any time.

7. Your rights

Under UK and EU data protection law (GDPR), and the CCPA if you’re in California, you can ask to access, download, correct or erase what we hold about you, or ask us to stop using it. If you’re unhappy with how we handle it, you can complain to the Information Commissioner’s Office at ico.org.uk.

8. Contact

For anything about your data, including removal, emailadmin@stag-ai.com from the address you signed up with, and we’ll deal with it.
