Subprocessors of Formius
Formius declares 13 subprocessors, including AI providers Anthropic, Google Gemini, OpenAI.
| Subprocessor | Purpose |
|---|---|
| Runs the Claude model for form generation and the form chat agent when Vercel AI Gateway routes the request with EU inference | |
| AI form generation, the form chat agent and its checks (Claude), and the fallback for lesson text generation. Form generation runs on one provider at a time, chosen in configuration: this one, Google Cloud or Vercel AI Gateway. Production uses this one through Vercel AI Gateway with inference pinned to the EU, so the model runs on Amazon Web Services Bedrock in Frankfurt. Also the fallback model for lesson text generation | |
| Error monitoring. We run GlitchTip, a Sentry-compatible error tracker, ourselves on Fly.io. The Sentry SDK in the app sends its reports to that server, not to Sentry | |
| AI form generation and editing. Form generation runs on one provider at a time, chosen in configuration: this one, Anthropic or Vercel AI Gateway | |
| Lesson text generation, optional AI feedback on lesson answers, and lesson illustration generation and validation, with inference pinned to the EU (Vertex AI EU) | |
| Not used by default since 2026-10-01, when lesson models moved to EU inference. Used only if a lesson model setting names an OpenAI model, which the EU inference option then refuses | |
| Product analytics | |
| Transactional email: submission confirmation links to respondents, and new response and form deletion emails to form owners | |
| Subscription billing, checkout, tax and customer portal | |
| Database, file storage and admin sign-in (one-time email codes) |
