Subprocessors
Last updated: July 24, 2026
A subprocessor is a third party we engage to process personal data on our behalf while providing Port Zero. This page lists every subprocessor currently in use, what it does for us, and where it processes data. It is referenced from our Privacy Policy and our Data Processing Addendum, and we keep the three documents in sync.
| Subprocessor | Purpose | Processing location |
|---|---|---|
| DigitalOcean | Application hosting, database, and log storage | United States (nyc3 region) |
| Stripe | Payment processing, billing, and invoicing | United States |
| SendGrid | Transactional email (verification codes, account notices) and optional marketing email | United States |
| PostHog | Product analytics and error tracking, loaded only after you accept analytics cookies | United States |
| Cloudflare | DNS for our domains | Global anycast network |
| GitHub | OAuth sign-in and identity verification | United States |
Where a subprocessor processes personal data of individuals in the European Economic Area or the United Kingdom, that transfer is covered by the European Commission's Standard Contractual Clauses (SCCs), as described in our Privacy Policy.
We will update this page before adding a new subprocessor or materially changing an existing one. If you want to be notified of changes, email legal@portzero.net.
