Subprocessors
The complete list. It's short because the platform is genuinely self-operated — most vendors on a typical email platform's list simply don't exist here.

| Subprocessor | Purpose | Data touched | Location |
|---|---|---|---|
| Hetzner Online GmbH | Dedicated server hosting (hardware; we operate the stack) | All platform data at rest, on our encrypted volumes | Germany (EU) |
| Stripe, Inc. | Payment processing — our billing, and reader payments for paid newsletters (arms at launch) | Payment details (never stored by us), billing contact | US/EU |
That's the list. Notably absent: no upstream email-delivery provider (we run our own mail infrastructure), no third-party analytics on customer data, no advertising systems, no AI-model vendors touching message content.
Changes are announced to DPA customers before a new subprocessor is added, with a right to object — see the DPA.
