Subprocessors
Last updated 22 August 2026
The service providers Kaizo Ltd uses to deliver Kaizo, what each one does for us, and the data each one touches.
Dental practices using Kaizo are the data controllers for their patient and enquiry data. Kaizo Ltd is their data processor and, as permitted under Article 28 of the UK GDPR, uses a small number of service providers (“subprocessors”) to deliver parts of the service. Each subprocessor is bound by a written data processing agreement and processes data only for the purpose shown below.
