Is Cuik SEO Extension safe?

Clean risk

Cuik SEO Extension sends audit URLs and Cuik account details to crawl.cuik.io when a user starts an SEO audit.

When you start an audit from the popup, the extension posts the target URL and page count to crawl.cuik.io. If you have connected a Cuik account, the request also includes your account email and an Authorization bearer token, then the extension connects to the same service for audit progress.
