This page lists the third-party providers ("Sub-processors") that CallGuard AI uses to deliver the Services. Each of these Sub-processors may Process Customer Personal Data on our behalf. We have entered into a written data-protection agreement with each Sub-processor that contains obligations no less protective than those set out in our Data Processing Agreement.

We notify customers of any addition or replacement of Sub-processors at least 30 days before the change takes effect. Customers may subscribe to updates by emailing privacy@callguardai.co.uk.

Reading this page: we group Sub-processors by purpose so customers can quickly assess data-protection risk for their use case. Where a Sub-processor is headquartered or processes data outside the UK, we identify the transfer safeguard that applies.

Customer-configured integrations

Where a customer chooses to integrate the Services with a third-party platform of their own (e.g., Twilio, AWS Connect, Vonage for live audio streaming; their own CRM or webhook endpoint), that third party is acting on the customer's instruction, not on ours. CallGuard AI does not enter into a Sub-processor relationship with these third parties on the customer's behalf. The customer is responsible for any DPAs or transfer safeguards required between themselves and those parties.
