Privacy Policy

Last updated: February 6, 2026

At LightDarkTools.com, we take your privacy seriously. This policy explains how we treat your data across our entire platform and suite of tools, including our Universal Diff Tool and Secure QR Code Generator.

1. Our Privacy Philosophy

We believe that your data belongs to you. Our tools are designed from the ground up to be "Privacy-First," meaning we process as much as possible directly on your device rather than on our servers.

2. Data Collection and Usage

2.1. 100% Client-Side Processing

The core functionality of our flagship tools operates entirely within your web browser.

• Universal Diff Tool: Your files and text comparisons are processed locally. We never upload, see, or store your content.
• Secure QR Code Generator: All QR code generation happens locally in your browser using JavaScript. No text, URLs, or Wi-Fi credentials are sent to any server.

2.2. No Account Required

You can use all our features, including the Secure QR Code Generator, without ever creating an account, logging in, or providing personal information like your name, email, or phone number.

3. Storage and Tracking

3.1. Local Storage

We use your browser's local storage solely to save your preferences (such as your theme choice). This data stays on your device and is never synchronized to our servers.

3.2. Cookies & Analytics

We do not use tracking cookies to follow you across the web. We may use anonymized, server-side traffic logs for security and performance monitoring, which do not identify you personally.

4. Third-Party Services

We use trusted Content Delivery Networks (CDNs) to deliver the libraries and fonts needed for our tools to work. These providers may handle standard technical data (like IP addresses) required for these requests in accordance with their own privacy policies.

5. Security

While our tools are designed to keep your data local, we encourage you to maintain a secure browser environment. We implement standard security practices on our website to ensure a safe experience for all users.

6. Changes and Contact

We may update this policy as we add new tools. If you have questions about your privacy at LightDarkTools, please reach out to us at lightdarktools@gmail.com.
