Subprocessors
Last updated: 4 November 2026
Current subprocessors
PortKnot uses the following subprocessors to provide the service. This list is incorporated into the DPA. We give at least 30 days' notice before adding a new subprocessor or materially changing its role.
| Subprocessor | Purpose | Data | Location / safeguard |
|---|---|---|---|
| Cloudflare, Inc. | Hosting, Workers, D1, R2, KV, rate limiting, Workers AI, email routing | Account, leads, communications, technical logs, backups | Global; SCCs / UK Addendum, DPF where certified |
| Resend, Inc. | Email delivery, inbound replies, domain and webhook management | Sender and recipient email, message content, delivery events, encrypted API key | United States; SCCs / UK Addendum, DPF where certified |
| OpenAI | AI drafting and reply classification | Product context, selected lead fields, email and reply text | United States; EU data residency available; SCCs / UK Addendum; API data not used for training by default |
| Lemon Squeezy, Inc. | Merchant of record, checkout, subscriptions, tax and receipts | Name, email, billing identifiers, plan and payment status | United States; SCCs / UK Addendum, DPF where certified |
| Apify | Public website crawling and lead discovery | Public URLs and extracted public business data | EU / United States; SCCs / UK Addendum |
Optional services are enabled only when configured by the customer: Postmark (email delivery; currently hidden), Slack (operational alerts), and Cloudflare Access (admin SSO). They appear here when active and are covered by the same safeguards.
Not subprocessors by default
Your own Resend account, DNS provider, email provider and cloud storage are your own services, not PortKnot subprocessors. PortKnot does not control their terms, retention or security.
Changes and objections
We publish changes on this page and notify workspace owners by email where required. You may object on reasonable data-protection grounds by emailing hello@portknot.com within 30 days. If we cannot resolve the objection, you may terminate the affected service and receive a pro-rata refund of prepaid fees.
