Sub-processors
Last updated: 2026-07-22.
These are the third parties that help us run Blockjay, what each one does, and roughly where it operates. We impose data-protection terms on each, and we keep this list current. To be notified of changes, contact [email protected].
| Sub-processor | Purpose | Region |
|---|---|---|
| Anthropic | Fallback AI classification of the uncertain mail band, when our own self-hosted model defers. Zero-retention, no-training. | United States |
| Stripe | Payment processing and subscription billing. | United States |
| Cloudflare | Network ingress, DNS, WAF/rate-limiting, access control, and transactional/report email delivery. | Global |
| Self-hosted / on-premises | Compute, database, and object storage for the service, including our own AI classification model. | United States |
For how these fit our data-protection commitments, see the data processing addendum, privacy policy, and security pages.
