By accessing or using the QVS (Quantum Vulnerability Scanner) service, you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the service.
QVS is a free, web-based tool that analyzes URLs, uploaded files, and pasted source code for cryptographic algorithms and assesses their vulnerability to quantum computing attacks. The service provides a quantum readiness score and recommendations based on NIST post-quantum cryptography standards (FIPS 203, 204, 205).
QVS is provided "as-is" and "as-available" without warranties of any kind, whether express, implied, or statutory. We specifically disclaim all implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
We do not warrant that:
QVS is an informational tool designed to provide a preliminary assessment of quantum cryptographic readiness. It is not a substitute for a comprehensive, professional security audit. Organizations should engage qualified security professionals for thorough cryptographic assessments, especially for critical infrastructure, regulated industries, or compliance requirements.
To the fullest extent permitted by applicable law, in no event shall QVS, its creators, contributors, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, use, goodwill, or other intangible losses, arising out of or in connection with your use of or inability to use the service.
This limitation applies regardless of the legal theory on which the claim is based, whether or not we have been advised of the possibility of such damages, and even if a remedy set forth herein is found to have failed its essential purpose.
You use QVS entirely at your own risk. You are solely responsible for any decisions or actions taken based on the results provided by the service. No liability is accepted for any damages, losses, or adverse outcomes arising from the use of this tool or reliance on its output.
You agree to use QVS only for lawful purposes. You shall not:
QVS does not store uploaded files, pasted code, or scan results beyond the duration of the active session. URL scans connect directly to the target server to retrieve TLS certificate information. No personal data is collected or retained unless you voluntarily provide it (e.g., email sign-up).
We reserve the right to modify these terms at any time. Continued use of the service after changes constitutes acceptance of the revised terms.
