Please do not provide sensitive personal information through the website contact form unless it is necessary.

5. Lawful bases for processing

Depending on the circumstances, I process personal information under one or more of the following lawful bases:

Steps before entering into a contract
When you ask about my availability, request a proposal or discuss possible work.

Performance of a contract
When processing is necessary to provide agreed services or manage our professional relationship.

Legitimate interests
Where it is reasonably necessary to respond to business enquiries, manage professional relationships, operate my business, protect the website or improve my services, provided those interests are not overridden by your rights.

Legal obligation
Where I must retain or disclose information to meet legal, accounting, tax or regulatory requirements.

Consent
Where you have actively agreed to the use of non-essential cookies or to receive particular communications. You may withdraw your consent at any time.

6. Sharing your information

I may share relevant information with trusted service providers where necessary, including:

  • Squarespace, which hosts and supports this website

  • email, calendar and cloud-storage providers

  • website analytics providers, where you have consented

  • accountants, insurers and professional advisers

  • subcontractors or professional collaborators involved in delivering agreed work, where appropriate

  • public authorities or regulators where disclosure is legally required

These parties may only receive the information reasonably necessary for the relevant purpose.

7. International transfers

Some service providers may process or store information outside the United Kingdom.

Where this occurs, I will rely on appropriate protections required by UK data protection law, such as an adequacy decision, approved contractual safeguards or another valid transfer mechanism.

Further information about the safeguards used by individual providers can be found in their privacy notices.

8. How long I keep information

I keep personal information only for as long as reasonably necessary for the purpose for which it was collected.

As a general guide:

  • enquiries that do not lead to work may normally be retained for up to 24 months

  • records relating to clients, projects, contracts, invoices and payments may normally be retained for up to seven years after the end of the relevant financial year or professional relationship

  • cookie and analytics information is retained according to the settings and retention periods of the relevant technology provider

Information may be retained for longer where this is necessary to comply with a legal obligation or establish, exercise or defend a legal claim.

9. How I protect information

I take reasonable technical and organisational measures to protect personal information against accidental loss, unauthorised access, alteration, disclosure or misuse.

However, no internet-based system can be guaranteed to be completely secure.

10. Your rights

Depending on the circumstances, you may have the right to:

  • be informed about how your information is used

  • request access to your personal information

  • ask for inaccurate or incomplete information to be corrected

  • request deletion of your information

  • request restriction of processing

  • object to particular uses of your information

  • request transfer of information you provided in a portable format

  • withdraw consent at any time where processing is based on consent

  • complain about the way your information has been handled

These rights are not absolute and may be subject to legal exceptions.

To exercise a right, contact me at [insert business email address]. I may need to verify your identity before completing a request.

11. Complaints

Please contact me first if you have any concern about how your information has been used, so that I can try to resolve it.

You also have the right to complain to the UK Information Commissioner’s Office.

Further information is available from the Information Commissioner’s Office at ico.org.uk.
