Self-hosted (not third-party SaaS)
Sync API, Postgres, y-sweet multiplayer, GlitchTip crash reporting, and this marketing site run on infrastructure operated by Informal Content Agency in the United States.
03
Customer-directed AI providers
When you connect OpenAI, Anthropic, OpenRouter, ComfyUI, or similar via BYOK or workspace keys, those providers process prompts as you direct under their terms. They are not default Informal subprocessors for all users.

Change process
We update this page and the repository list when material subprocessors change. Business customers may request notice at the legal contact on the Privacy Policy. Vendor DPAs are executed where required (counsel / ops residual for countersignatures).
