The direct answer

A crawler instruction does not require a browser or unauthorized visitor to stay out. Private content needs authentication and authorization, not merely a robots rule.

Start with the evidence

Open protected routes without signing in and inspect their actual responses using approved tests. Confirm that sensitive content is not included in publicly served HTML or data files.

Make the change deliberately

Protect private resources server-side. Use crawler controls for crawl policy separately, and never describe a page as secure solely because a robots file disallows it.

Platform guidance can change. Consult the current official documentation before making platform-specific changes.
