Terms of Service

Last updated: 16 March 2026

These terms govern your use of StackFlag (stackflag.com), operated by StackFlag ("we", "us", "our"). By creating an account or using the service, you agree to these terms.

The service

StackFlag monitors public vulnerability databases and alerts you when vulnerabilities match the software you have defined in your stack. We provide plain-English summaries, severity ratings, and remediation guidance.

StackFlag is currently in free beta. Features, limits, and pricing may change.

Your account

  • You must provide a valid email address and verify it before using the service.
  • You are responsible for keeping your login credentials secure.
  • You must not share your account or create multiple accounts.
  • We may suspend or delete accounts that violate these terms.

Acceptable use

You agree not to:

  • Use the service for any unlawful purpose.
  • Attempt to access other users' data or accounts.
  • Interfere with the operation of the service (automated scraping, denial-of-service, etc.).
  • Misrepresent your identity or affiliation.

Data and content

  • Vulnerability data is sourced from public databases (NVD, GHSA, OSV, CISA KEV, EPSS, Vulnrichment). We do not guarantee its accuracy or completeness.
  • AI-generated summaries are provided for convenience and may contain errors. They are not a substitute for professional security advice.
  • Your stack definitions, alert configurations, and flag history are stored in our database and accessible only to you and your team.

Availability

We aim for high availability but do not guarantee uninterrupted service. We may perform maintenance, change features, or discontinue the service at any time with reasonable notice.

Limitation of liability

StackFlag is provided "as is" without warranty of any kind. To the maximum extent permitted by law, we are not liable for any damages arising from your use of the service, including missed vulnerabilities, delayed alerts, or inaccurate AI summaries.

Changes to these terms

We may update these terms from time to time. We will notify registered users by email of material changes. Continued use of the service after changes take effect constitutes acceptance of the new terms.
