Privacy

Privacy Policy

Cornerstones collects only the information needed to operate account access, API keys, billing status, product support, and abuse prevention for hosted and client-facing surfaces.

Information we process

This can include sign-in profile details from managed OAuth providers, API-key metadata, subscription state, contact form messages, request metadata needed for rate limits, and operational logs used to keep the service reliable.

How we use it

We use this information to provide the dashboard, issue and verify API keys, apply plan gates, process support requests, improve reliability, and protect the service from misuse.

What we do not ask for

Cornerstones API keys are separate from broker, exchange, OpenAI, or upstream data-provider credentials. Do not paste those third-party secrets into contact messages or prompts unless a secure support workflow has been explicitly arranged.
