> The providers BYOM relies on, and what each one does.

## Infrastructure

Google Cloud Platform. Hosting, database and build, with durable data held in the UK.

## Model providers

Model providers are selected per workspace. Merchant data is not used to train models shared with other merchants. You approve every change, whichever model drafted it.

## Operations

Transactional email for approval notices and account mail. Error and performance monitoring for the runtime.

## Notice

We give notice before adding a subprocessor. To receive that notice, write to hello@byom.co.
