Terms of Service

Last updated: April 18, 2026

User agreement and acceptance

By accessing and using PassGuard Check (the “Service”), you accept and agree to be bound by these Terms of Service (“Terms”). If you do not agree to these Terms, you must not use the Service.

These Terms constitute a legally binding agreement between you (the “User”) and PassGuard Check. We reserve the right to modify these Terms at any time. Continued use of the Service after changes are posted constitutes acceptance of the modified Terms.

You must be at least 13 years old to use this Service. By using PassGuard Check, you represent and warrant that you meet this age requirement.

Permitted use and restrictions

PassGuard Check is provided as a free educational tool for testing password strength and generating secure passwords. You are granted a limited, non-exclusive, non-transferable license to use the Service for personal, non-commercial purposes.

Permitted uses

• Testing the strength of passwords for personal accounts
• Generating secure passwords for your own use
• Learning about password security best practices
• Checking passphrases against common password databases

Prohibited uses

You agree not to:

• Use the Service to test passwords you do not own or have authorization to test
• Attempt to reverse engineer, decompile, or extract source code from the Service
• Use automated tools, bots, or scripts to access the Service at scale
• Interfere with or disrupt the Service’s infrastructure or servers
• Use the Service for any illegal or unauthorized purpose
• Redistribute, resell, or create derivative works based on the Service
• Remove or obscure any copyright, trademark, or proprietary notices

Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.

PassGuard Check makes no warranties or representations about:

• The accuracy, reliability, or completeness of password strength assessments
• The security of passwords generated by the Service
• The Service’s availability, uptime, or freedom from errors
• The suitability of the Service for any particular purpose

While we strive to provide accurate password strength analysis, the Service is an educational tool and should not be relied upon as the sole method for evaluating password security. We recommend using established password managers and following industry best practices for credential management.

The Service analyzes passwords based on common patterns, dictionary words, and entropy calculations. However, no password strength checker can guarantee absolute security, and determined attackers may use methods not accounted for in our analysis.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, PASSGUARD CHECK SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SERVICE.

This includes, but is not limited to, damages for:

• Loss of data, passwords, or account access
• Unauthorized access to your accounts or systems
• Security breaches resulting from weak passwords
• Reliance on password strength assessments provided by the Service
• Service interruptions, errors, or unavailability

In no event shall PassGuard Check’s total liability to you exceed the amount you paid to use the Service (which is zero, as the Service is free).

You acknowledge that you use the Service at your own risk and are solely responsible for:

• Choosing and managing your passwords
• Securing your accounts and devices
• Following security best practices
• Using trusted password managers for storing credentials

Intellectual property rights

All content, features, and functionality of PassGuard Check, including but not limited to text, graphics, logos, icons, images, audio clips, digital downloads, data compilations, and software, are the exclusive property of PassGuard Check or its licensors and are protected by international copyright, trademark, patent, trade secret, and other intellectual property laws.

The PassGuard Check name, logo, and all related names, logos, product and service names, designs, and slogans are trademarks of PassGuard Check. You may not use these marks without our prior written permission.

You retain all rights to any passwords or content you input into the Service. We do not claim ownership of your data, and as stated in our Privacy Policy, we do not store or have access to the passwords you test.

User responsibilities

As a user of PassGuard Check, you are responsible for:

• Maintaining the security of your devices and internet connection
• Using the Service in compliance with all applicable laws and regulations
• Not testing passwords that belong to others without authorization
• Understanding that the Service is educational and not a substitute for professional security advice
• Implementing proper password management practices beyond using this tool
• Not relying solely on this Service for critical security decisions

We strongly recommend:

• Using a reputable password manager to store your actual passwords
• Enabling two-factor authentication on all accounts that support it
• Never reusing passwords across multiple accounts
• Regularly updating passwords for sensitive accounts
• Being cautious about testing real passwords on any online tool, including ours

Service modifications and termination

We reserve the right to:

• Modify, suspend, or discontinue the Service at any time without notice
• Change these Terms of Service at our discretion
• Refuse service to anyone for any reason
• Update features, algorithms, or functionality of the password checker

We will make reasonable efforts to notify users of significant changes to the Service or these Terms, but we are not obligated to do so. Your continued use of the Service after changes constitutes acceptance of the modified Terms.

We may terminate or suspend access to the Service immediately, without prior notice or liability, for any reason, including if you breach these Terms.
