Sub-processors

Last updated 11 September 2026

These are the third parties that process data on our behalf to run Inkhost. It is the list referred to by the Data Processing Addendum and the privacy policy.

A note on the AI providers

Anthropic, OpenAI, Google and Firecrawl only receive data when you invoke a feature that needs them. A blog that never uses an AI action and never requests a business brief sends them nothing.

Providers you bring yourself

If you connect your own email provider account, mail for your blog is sent through your account under your contract with that provider, not ours. In that arrangement they are your processor rather than our sub-processor.

Changes to this list

We will update this page before a new sub-processor starts handling customer data, and the date at the top will change with it. If you have a signed data processing addendum with us and want advance notice by email, write to privacy@inkhost.app and we will add you to the notification list.
