Companies House Registry (BYOK) — Privacy Policy

Effective 16 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Companies House Registry (BYOK) is. Companies House Registry (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Companies House Registry data: Run advanced, alphabetical and dissolved company searches and read registered office, insolvency, exemptions and register locations from the Companies House public data API with your own key. You bring your own Companies House Registry Companies House API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Companies House Registry call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.company-information.service.gov.uk, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Companies House Registry rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Companies House Registry receives. The request we make on your behalf, including the key and the arguments, under Companies House Registry's own terms and privacy policy (https://developer.company-information.service.gov.uk/developer-guidelines). Companies House Registry acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Companies House Registry gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Companies House Registry data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Companies House Registry (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Companies House Registry at any time to end all access.

Children. Companies House Registry (BYOK) is a general-audience service operated by the adult using the assistant, under Companies House Registry's own age rules.

Changes. We will post changes here with a new effective date.
