Subprocessors
Last updated 27 September 2026
These are the services that help us run Kairo Post. We give each one only the data it needs for its purpose.
| Service | Purpose | Data |
|---|---|---|
| Railway | Application hosting, databases and job queues | Account, workspace and content data; operational logs |
| Whop | Hosted checkout, subscriptions and payment processing | Purchaser identity, payment and subscription status |
| X Corp. | Publishing and account authorization via the official API | Posts, media and actions you authorize for connected accounts |
| Resend | Transactional email delivery | Email address and message content for notifications |
| Object storage provider (S3-compatible) | Private storage for uploaded and generated media and exports | Media files and export archives |
| AI model providers you select | Drafting text and images when you request it | Only the material you choose to send with each request |
Where you connect your own AI provider key, that provider processes requests under your agreement with them. We'll update this list before adding a new subprocessor. To be notified of changes, email privacy@kairopost.com.
