Privacy Policy

Last updated: 7 September 2026

This policy explains how I collect, use and protect your personal information when you visit this website or work with me as a client. I take your privacy seriously, particularly given the sensitive nature of therapy.

Who I am

This website is operated by Tom Warmerdam, a Cognitive Behavioural Hypnotherapist providing online therapy.

For the purposes of UK data protection law, I am the data controller for the information described in this policy.

What information I collect

When you contact me

If you complete the enquiry form or contact me by phone or email, I collect your name, email address, telephone number, your preferred method of contact, and whatever you choose to tell me about what you would like help with.

You do not need to share detailed personal or medical information at this stage. A brief description is enough.

When you become a client

If we go on to work together, I will collect further information as part of your assessment and ongoing sessions. This may include your contact details, date of birth, GP details, relevant medical and mental health history, current medication, and notes recording the work we do together.

When you visit this website

This website does not use tracking or advertising cookies, and no cookie banner is required. My hosting provider, Netlify, records standard technical information such as IP addresses and pages requested in order to deliver the site securely.

Special category data

Information about your physical or mental health is treated as special category data under UK GDPR, which means it receives a higher level of protection.

I process this information on the basis of Article 9(2)(h) — the provision of health and social care — and I handle it under a duty of confidentiality. It is never used for marketing and never shared for commercial purposes.

Why I use your information, and my lawful basis

How long I keep it

Who I share it with

Your information is confidential and is not sold, rented or shared for marketing. I use a small number of service providers who process data on my behalf under written agreements:

Some of these providers are based outside the UK. Where that is the case, transfers are protected by UK-approved safeguards such as the International Data Transfer Agreement or adequacy regulations.

Clinical supervision

As is standard professional practice, I discuss my work in supervision to maintain the quality and safety of the therapy I provide. Clients are referred to anonymously and identifying details are not shared.

When I may need to break confidentiality

In rare circumstances I may need to share information without your consent — where there is a serious risk of harm to you or another person, where a child or vulnerable adult may be at risk, or where I am required to do so by law or a court order. Wherever it is safe and appropriate, I will discuss this with you first.

Your rights

Under UK data protection law you have the right to:

To exercise any of these, email hello@tomwarmerdam.co.uk. I will respond within one month.

How your information is kept safe

Electronic records are stored on password-protected, encrypted devices. Any paper records are kept in a locked cabinet. Records are stored separately from identifying details where practical, and I review my security arrangements regularly.

Complaints

If you are unhappy with how I have handled your information, please contact me first so I can try to put it right. You also have the right to complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.

Changes to this policy

I may update this policy from time to time. Any changes will be posted here with a revised date at the top of the page.
