Subprocessors
Last updated: April 28, 2026
Every third party that processes customer data on System2's behalf is listed below. We notify customers at least 30 days before adding a new one.
What's a subprocessor
A "subprocessor" is a third party that processes Customer Content on System2's behalf to help us operate the Service. Hosting providers, error trackers, our LLM provider — all subprocessors. We use the minimum number needed.
Disclosure of subprocessors and prior notice of changes is required by Article 28(2) of the GDPR and by analogous provisions in our Data Processing Addendum.
Production subprocessors
| Provider | Purpose | Data processed | Location |
|---|---|---|---|
| Anthropic, PBC | Large language model inference (Claude) | Customer Content (chat messages, files attached to chats, tool inputs and outputs) | United States |
| Supabase, Inc. | Managed Postgres database, authentication, storage | All Customer Content; account credentials; encrypted Integration tokens | United States (us-east-1) |
| Fly.io (Fly Apps Inc.) | API server hosting, worker runtime | Request payloads in transit; ephemeral logs | United States, plus global edge as configured |
| Vercel, Inc. | Web (UI) hosting and edge delivery | Static assets and request metadata; no Customer Content stored at rest | Global edge (primary: United States) |
| Cloudflare, Inc. | DNS, edge network, DDoS protection | IP addresses, request metadata, TLS handshake data | Global edge |
| Functional Software, Inc. (Sentry) | Error monitoring and performance tracing | Stack traces, request URLs, user IDs. Authorization/cookie headers and sensitive body keys (passwords, tokens, secrets, API keys) are redacted server-side before events leave our process; stack-trace context can still incidentally include other Customer Content. | United States |
| Better Stack (Better Stack Sp. z o.o.) | Uptime monitoring and incident alerting | Endpoint response codes and latency only; no Customer Content | European Union |
| GitHub, Inc. | Source code repository, CI/CD | No Customer Content. Account-related metadata when employees act on issues that reference customer reports. | United States |
Integration providers (not subprocessors)
When you connect a third-party service to System2 (e.g. Linear, Notion, Slack, Gmail, HubSpot), that provider becomes a recipient of the data you direct System2 to send it.
These providers are not subprocessors— they are independent controllers governed by their own terms and privacy policies. You are responsible for reviewing each provider's terms before connecting and for the data you choose to share with them through the Service.
Anthropic data handling
Because Anthropic processes the largest portion of Customer Content (every chat goes through them), the specifics matter. Per our agreement with Anthropic and their published commercial terms:
- Customer Content sent to Claude is not used to train Anthropic's models.
- Anthropic retains API inputs and outputs for up to 30 days by default. Where a request is flagged for trust- and-safety review, Anthropic may extend retention up to 2 years for inputs/outputs and up to 7 years for the related trust-and-safety classifications. See Anthropic's data-retention documentation for current details.
- Anthropic operates from the United States; data may transit other regions Anthropic uses for inference capacity.
- Reference: Anthropic Commercial Terms.
How we add new subprocessors
Before engaging a new subprocessor that will process Customer Content, we:
- Review their security posture and data practices.
- Sign a data-processing agreement that imposes the same or stronger obligations than our DPA with you.
- Update this page at least 30 days before the new subprocessor begins processing Customer Content.
- Notify subscribed customers (see the next section).
Subprocessor change notifications
We notify customers of new subprocessors:
- By email to account admins at least 30 days before the new subprocessor begins processing Customer Content.
- By updating this page on the same day the email goes out.
- In our changelog (in-product release notes) for visibility.
To subscribe to subprocessor change notifications, email privacy@autono.sh with the subject line "Subprocessor notifications" and the email address(es) you want notified. We will add you to the announcement list.
Objecting to a new subprocessor
If you reasonably object to a new subprocessor on data-protection grounds, contact us within the 30-day notice period at privacy@autono.sh. We will work with you in good faith to find an alternative. If we can't, you may terminate the affected portion of the Service for cause without penalty.
