Last updated: January 21, 2026

Introduction

Welcome to wvtou.com ("we," "our," or "us"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we handle information when you use our website and tools.

This website is operated by an independent developer specializing in password security and cryptography education tools. We are committed to transparency about our data practices.

Information We Collect

Data You Provide Through Our Tools

We do not collect or store the data you input into our tools. Our security tools are designed to process all data locally in your browser. This means:

  • Passwords you generate or analyze are never sent to our servers
  • Encrypted/decrypted content remains on your device
  • Hash values are calculated locally
  • No user accounts or registration required

Automatically Collected Information

When you visit our website, we may automatically collect certain information through cookies and similar technologies:

  • Browser type and version
  • Device type (desktop, mobile, tablet)
  • Operating system
  • IP address (anonymized where possible)
  • General geographic location (country/region level)
  • Pages visited and time spent on pages
  • Referring website or source

Cookies

Our website uses cookies for the following purposes:

  • Essential Cookies: Required for basic website functionality (e.g., theme preference)
  • Analytics Cookies: Help us understand how visitors use our website

We do not use tracking cookies or share data with third-party advertisers. For detailed information about the cookies we use, please see our Cookie Policy.

How We Use Information

Data Sharing

We do not sell your personal information. We may share anonymized, aggregated data with third parties for analytics purposes. Information may be shared with:

  • Service Providers: Who help us operate our website (hosting, CDN)

Data Security

Since all cryptographic operations occur in your browser, your sensitive data (passwords, encryption keys, etc.) never leaves your device. We use HTTPS encryption for all communications to ensure the security of our website.

While we implement reasonable security measures, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security of any information transmitted to our website.

Children's Privacy

Our services are not directed to children under 13 (or 16 in certain jurisdictions such as the European Economic Area). We do not knowingly collect personal information from children. If you believe we have collected information from a child, please contact us immediately.

International Data Transfers

Our website may be accessed from various countries. If you access our website from outside the United States, please be aware that your information may be transferred to, stored, and processed in the United States where our servers are located.
