Ji4Sub-processors
Last updated 29 July 2026
This page lists the sub-processors OS Informatics Limited uses to provide Ji4 on behalf of customer workspaces, and the service providers used for Ji4's own account and billing processing. It supplements the Ji4 Privacy Policy and Data Processing Agreement.
1. Sub-processors
The table below lists the sub-processors Ji4 currently uses to provide the Service. A Data Processing Agreement, including our current transfer mechanism per sub-processor, is available on request.
| Sub-processor | Purpose | Data received |
|---|---|---|
| Anthropic, PBC | AI assisted drafting of Linear issues and replies from support conversations (primary provider) | The ticket subject and the customer-visible message thread, for the ticket being drafted |
| OpenAI, L.L.C. | AI assisted drafting, as a failover provider if Anthropic is unavailable; embeddings for duplicate detection and semantic search | The ticket subject and the customer-visible message thread (drafting failover); ticket and message content used to generate embeddings |
| Postmark (AC PM, an ActiveCampaign company) | Inbound and outbound email: parsing inbound support email into tickets, and sending outbound replies and notifications to End Users | Email addresses, message content and attachments |
| Stripe, Inc. | Billing and payment processing for Ji4 subscriptions. Ji4 acts as controller for this processing (see the Privacy Policy); Stripe is not engaged as a GDPR Article 28 sub-processor for workspace support content | Billing name, address, email, VAT number and transaction records. Ji4 does not receive or store payment card numbers |
| [HOSTING PROVIDER] | Hosting of the application, database and file storage, on EU infrastructure | All Customer Data and account data held by Ji4 |
Linear is not a Ji4 sub-processor. When you connect your own Linear workspace, that is a transfer you initiate to your own Linear account, governed by your own relationship with Linear, and is not something Ji4 does as a sub-processor on a customer's instructions.
A Data Processing Agreement, including our current Standard Contractual Clauses position per sub-processor, is available on request.
2. Adding or changing sub-processors
We will give at least 30 days' notice before adding or replacing a sub-processor used to process Customer Data, as described in our Data Processing Agreement, so that customers can review the change before it takes effect.
