# Privacy

Calcgrid is a public, account-free calculator service. It does not set cookies, use browser tracking scripts, require names or email addresses, or intentionally persist raw calculator input values or calculation result values in its application analytics dataset.

## Operational telemetry

For reliability, abuse prevention and measurement of genuine AI/Agent use, Calcgrid records limited request metadata in Cloudflare Analytics Engine: timestamp, request method and path, response status and content type, processing time, country code supplied by Cloudflare, user-agent string and a coarse client class, referrer when sent by the client, protocol method, tool name or calculator id, declared MCP client name/version, optional `Calcgrid-Client` header, and Cloudflare-provided verified-bot or signed-agent signals when available.

The application telemetry does not write the raw client IP address, request parameter values, MCP tool arguments, calculation outputs, authorization secrets or message text. Cloudflare may process network identifiers independently to deliver and protect the service under its own terms.

## Purpose and sharing

Telemetry is used to diagnose errors, maintain the service, enforce fair-use limits, distinguish discovery traffic from completed calculations, and improve tool selection. Calcgrid does not sell this telemetry. Data may be processed by Cloudflare as the hosting and analytics provider or disclosed when legally required.

Do not send personal, confidential or regulated information in calculator inputs. See [support](https://tttkmbb.com/docs/support.md) for operational questions.
