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.
