Sub-processors

Last updated: 22 April 2026

Who we use to deliver the service

ChatIFA relies on the third-party services below to operate. Each one processes a specific, documented slice of data — we don't share customer or visitor data with any party outside this list without telling you first.

If we add or change a sub-processor, we'll update this page and notify customers at least 14 days before the change takes effect, unless the change is required urgently for security or legal reasons.
