Privacy notice

Last updated 16 October 2026

The short version. I only collect what I need to reply to you, run your audit or membership, and keep the records the law asks for. I never sell your data or add you to a mailing list.

If I emailed you first: I found your work details in public business sources, and I'll stop the moment you say "no thanks".

Who I am

Turnglass is a trading name of Colin Henderson, a sole trader. I decide how your personal data is used, which makes me the “controller” under UK data protection law.

Contact: hello (at) tryturnglass.com
Address: 20-22 Wenlock Road, London N1 7GU

If I contacted you first

I write to owners of online shops and small businesses about the audit. This section covers that outreach.

Your right to object. You can tell me to stop at any time and I will. Reply “no thanks” to any message, or email me. I’ll keep your email address on a short do-not-contact list so I never contact you again by mistake. That’s the only thing I keep.

Why I use it

I won’t add you to a mailing list, and I never sell your data.

Who sees it

Me, plus the services that make this work: Namecheap, which hosts this website and the form; Google Workspace, my email provider; the form, file and document tools I use to run the audit; and AI tools that help me sort and summarise logs and draft messages. I only use AI tools on terms that don’t let the provider train its models on what I send. If you become a member, the people on my team who work on your jobs see only what they need for those jobs, under confidentiality terms. If I ever bring in someone to help with your audit, I’ll tell you first.

Some of these providers may store data outside the UK, including in the USA. When they do, I rely on the safeguards UK law requires, such as the UK-US data bridge or standard data protection clauses.

How long I keep it

Your rights

You can ask to see the data I hold about you, correct it, delete it, or object to or limit how I use it, and you can ask for a copy to take elsewhere. You can object to marketing at any time. Just email me. If you’re unhappy with how I’ve handled your data, you can complain to the Information Commissioner’s Office at ico.org.uk/make-a-complaint.

If I change this notice, I’ll update the date at the top.
