Subprocessors
Subprocessors
The companies that process data on RelayLink's behalf, where they do it, and for what. The privacy policy summarises this list and the data processing addendum refers to it. Last updated 5 September 2026.
The list
| Company | What it does for us | What it can see | Where |
|---|---|---|---|
| Microsoft Corporation (Microsoft Azure) | Hosts the application, the database, the secrets store, the logs and the performance telemetry. | Everything the service stores, encrypted at rest with Microsoft's keys. Microsoft's staff do not have standing access to customer data under its own terms. | United States (Central US region; backups replicated to a second US region). |
| Mailgun Technologies, Inc. (part of Sinch) | Sends every email the service sends and receives every reply sent to it by email. | The address, name and content of each notification and each emailed reply, and delivery logs. Open and click tracking are turned off. | United States. |
| Cloudflare, Inc. | Hosts the DNS zone for relaylink.ai. | The DNS lookup your network makes for the domain. No traffic, no content: every record is set to point directly at Azure, not through Cloudflare. | Global (a DNS lookup is answered from the nearest location). |
| GitHub, Inc. (a Microsoft subsidiary) | Holds the source code and runs the deployment pipeline that builds the service and applies database schema changes. | The pipeline holds an identity that can reach the database during a deployment. It changes the database's structure and never reads correspondence; no personal data is stored at GitHub. | United States. |
Who is not on it, and why
- The assistant you connect — Claude, ChatGPT, Claude Code, an agent framework — is not our subprocessor. You chose it, you connected it, it acts for you, and you can disconnect it at any moment from your connections page. Its provider's terms govern what it does with what it reads; the privacy policy says so.
- A payment processor will be added here before the first charge is ever taken. Nothing bills today and no card details are held anywhere.
- No analytics, advertising, support-desk, chat-widget or marketing-email provider, because the service uses none. The founding-list notice is sent by a person, through the same email provider above.
When the list changes
We update this page at least thirty days before a new subprocessor begins processing personal data, except where one has to be replaced urgently to keep the service secure or running, in which case we update it as soon as we can. An account holder who wants to be emailed about changes can ask at the address below; a business customer's rights to object are in section 6 of the data processing addendum. Each of the companies above processes under a written contract that includes data protection terms and, for transfers from the EEA, the UK and Switzerland, the standard contractual clauses.
