Sub-processors, and where data lives

Last updated 15 October 2026

Ruyo runs its backend, database and file storage in London. To transcribe conversations, write the coaching and answer questions, it sends data to the specialist providers below. Each one acts on our instructions, under its business or API terms, and only to provide its service to us.

Where data lives

Backend: Fly.io, London. Database and file storage, including recordings: Supabase, London. Data moves between the app, the backend and the providers over encrypted connections. Each business’s data is separated from every other business’s, recordings are in private storage, and provider keys are held only on our servers.

Where a provider processes data outside the UK, the transfer is made under a mechanism recognised by UK law: the UK International Data Transfer Addendum to the standard contractual clauses, or the UK-US data bridge where the provider is certified under it, as applicable to that provider. We do not use conversations to train AI models of our own, and we turn off model training where a provider offers that setting.

Changes to this list

We give businesses at least 30 days’ notice by email before adding or replacing a provider that processes their conversation data, and they may object on reasonable data-protection grounds in that period. The history of this page is in the date at the top. The full picture of what we collect and why is in the privacy notice.
