Fast2SMS (BYOK) — Privacy Policy

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

What Fast2SMS (BYOK) is. Fast2SMS (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Fast2SMS data: Read your Fast2SMS wallet balance, SMS delivery summary, DLT sender IDs and WhatsApp Business numbers, quality ratings and health with your own API key. You bring your own Fast2SMS Fast2SMS API authorization key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Fast2SMS 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 www.fast2sms.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Fast2SMS 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 Fast2SMS receives. The request we make on your behalf, including the key and the arguments, under Fast2SMS's own terms and privacy policy (https://www.fast2sms.com/terms-conditions). Fast2SMS acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Fast2SMS 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 Fast2SMS 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. Fast2SMS (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 Fast2SMS at any time to end all access.

Children. Fast2SMS (BYOK) is a general-audience service operated by the adult using the assistant, under Fast2SMS's own age rules.

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