We use the following third-party services that may process your personal data:

Each third-party service operates under its own privacy policy. We have satisfied ourselves that these providers maintain appropriate data protection standards.

7. Data sharing and transfers

We do not sell your personal data to third parties.

We may share your data with the third-party service providers listed in Section 6, solely for the purposes described. These providers act as data processors on our behalf and are contractually required to process your data only as we instruct.

Some of these providers (including Google and Vbout) may transfer data outside the United Kingdom. Where this occurs, we ensure appropriate safeguards are in place, such as Standard Contractual Clauses approved by the UK Information Commissioner’s Office, or transfers to countries recognised as providing an adequate level of data protection.

We may also disclose your data where required to do so by law, regulation or court order.

We retain your personal data only for as long as necessary to fulfil the purposes for which it was collected:

  • Contact form submissions and related correspondence: retained for 2 years from the date of your last interaction, unless a client relationship is established.
  • Mailing list data: retained until you withdraw consent by unsubscribing.
  • Analytics data: retained in accordance with the retention settings of our analytics provider (currently 14 months for Google Analytics).

Where a client engagement follows an initial enquiry, data retention is governed by the terms of that engagement and applicable legal requirements.
