# About PrivacyKit: Independent Zero-Knowledge Security Tools

> Built by SystemRootMedia. Free Forever. Zero Data Tracking.

## AI Overview — Our Core Mission
PrivacyKit is an independent, non-commercial cybersecurity and privacy research initiative engineered by SystemRootMedia. Our goal is to provide enterprise-grade privacy audit utilities—such as password entropy checking, IP geolocation lookup, and email breach scanning—to everyone completely free, with zero account registration and zero data collection.

## What Are PrivacyKit's Core Privacy Guarantees?
- **100% Free Forever:** All security tools on PrivacyKit are free for personal, commercial, educational, and developer use. No hidden fees or paywalled features.
- **No Accounts or Registrations:** We never ask for your email address, phone number, or credentials to use our software suite.
- **Zero Third-Party Ad Trackers:** We do not host invasive ad networks, cross-site tracking pixels, or data-broker profiling scripts.
- **Client-Side Zero-Knowledge Privacy:** All password checks, entropy calculations, and string parsing run locally in your web browser. No data ever reaches our servers.

## Who Develops and Maintains PrivacyKit?
PrivacyKit was conceived and built by the cybersecurity and information engineering team at **SystemRootMedia**. Frustrated by online tools that require accounts, monetize user queries, or send sensitive credentials over unencrypted endpoints, we built PrivacyKit to set a standard for zero-knowledge web security software.

## What Standards and Cryptographic Methods Are Used?
- **NIST SP 800-63B Compliance:** Password strength scoring evaluates Shannon entropy and dictionary vulnerability rather than forcing arbitrary character rules.
- **W3C Web Cryptography API:** Cryptographic hashing operations utilize high-performance, native browser APIs (`window.crypto.subtle`).
- **k-Anonymity Privacy Model:** Email breach verification uses 5-character SHA-1 prefix matching to search historical leak databases without revealing the user's email.

## Feature Comparison
| Security Feature | PrivacyKit Architecture | Typical Security Websites |
| :--- | :--- | :--- |
| **Data Processing** | 100% In-Browser (Client-Side) | Sent to Cloud Backend |
| **User Account** | None Required | Often Required / Paywalled |
| **Cryptography Standards** | NIST SP 800-63B & k-Anonymity | Arbitrary Complexity Rules |
| **Query Logging** | Zero Server Logs Stored | Logged in Database / Analytics |

## Editorial Standards & Security Review Protocols
- **Primary Authority Grounding:** Every guide, benchmark, and mathematical recommendation is grounded in official, peer-reviewed standards published by NIST, CISA, and IETF.
- **Zero-Fluff Technical Accuracy:** We avoid generic security clichés, sponsored tool bias, and manufactured scare tactics. All password crack times, hash entropy ratings, and breach vectors are verified through reproducible cryptanalysis and GPU benchmark data.
- **Open Architecture Auditing:** Users and developers can inspect our network traffic in browser developer tools (F12) to confirm that no queries, passwords, or IP lookups are transmitted to private tracking backends.

## Frequently Asked Questions
- **Who owns and operates PrivacyKit?**
  PrivacyKit is owned, developed, and maintained independently by SystemRootMedia, a digital security and information architecture media group.
- **How does PrivacyKit fund its operations?**
  PrivacyKit is privately funded by SystemRootMedia as a public interest open security project. We do not accept advertising sponsorships that require tracking user activity.
