-# Tools App
+# Tools App 🛠️
+
+A collection of useful developer tools in one place. Built with Vue 3 and Vite.
+
+**Live App:** [https://tools.7u.pl/](https://tools.7u.pl/)
+
+## Available Tools
+
+### 🔐 Bulk Passwords Generator
+Generate strong, secure passwords in bulk.
+- Customizable character sets (lowercase, uppercase, digits, special characters).
+- Option to skip similar characters (e.g., `l`, `1`, `I`, `O`, `0`).
+- Adjustable length and quantity.
+- Generates thousands of passwords instantly.
+
+### 📋 Clipboard Sniffer
+Monitor and capture your clipboard history in real-time.
+- **Web Mode:** Works when the tab is active and focused.
+- **Background Mode (with Extension):** Captures clipboard changes even when you are working in other applications or tabs.
+- Clears history on demand.
+- Privacy-focused: Data is processed locally and never sent to any server.
+
+---
+
+## Chrome Extension 🧩
+
+To unlock the full potential of the **Clipboard Sniffer**, you can install the companion Chrome Extension.
+
+### Why install the extension?
+By default, web browsers restrict clipboard access to when the tab is active and focused. The **Tools App Extension** runs in the background, allowing the application to detect clipboard changes even when you are using other apps or browsing different websites.
+
+### Features
+- **Background Monitoring:** seamlessly captures copied text while you work.
+- **Smart Integration:** automatically connects to the Tools App when open.
+- **Privacy First:** The extension only communicates with the Tools App (`tools.7u.pl` or `localhost`). No data is sent to third-party servers. [Privacy Policy](https://tools.7u.pl/extension-privacy-policy)
+
+### Installation
+1. Download the latest release or build from source.
+2. Open Chrome and navigate to `chrome://extensions/`.
+3. Enable "Developer mode" in the top right.
+4. Click "Load unpacked" and select the `extension` folder (or drag and drop the `.zip` file).
+
+---
+
+## Development
+
+### Project Setup
+```bash
+npm install
+```
+
+### Run for Development
+```bash
+npm run dev
+```
+
+### Build for Production
+```bash
+npm run build
+```
+
+### Build Extension
+To create a production-ready zip file for the Chrome Extension:
+```bash
+python3 scripts/build_extension.py
+```
+This will generate `extension-release.zip` in the project root.

+# Tools App Extension 🚀
+
+This is the companion Chrome Extension for **Tools App** ([tools.7u.pl](https://tools.7u.pl/)).
+
+## Overview
+**Tools App Extension** enhances your experience with the Tools App, specifically designed to power the **Clipboard Sniffer** tool. By default, web applications can only read your clipboard when the browser tab is active and focused. This extension runs in the background, allowing you to capture clipboard history seamlessly while you work in other applications or browse different websites.
+
+## Key Features
+- **Background Clipboard Monitoring:** Automatically captures copied text even when the Tools App tab is in the background.
+- **Privacy-First Design:** All clipboard data is processed locally within your browser and sent directly to the open Tools App tab. **No data is ever sent to external servers.**
+- **Smart Activation:** The extension only activates when you explicitly start the "Clipboard Sniffer" tool in the web app. It stops monitoring immediately when you stop the tool or close the tab.
+- **Visual Feedback:** The extension icon changes to indicate when it is actively monitoring your clipboard.
+
+## How it Works
+1. Open [tools.7u.pl](https://tools.7u.pl/) and navigate to the **Clipboard Sniffer** tool.
+2. The web app will detect the extension and show a "Connected" status.
+3. Click "Start Sniffing". The extension will begin monitoring clipboard changes in the background.
+4. Any text you copy (from any application) will appear in the Tools App list.
+5. Click "Stop Sniffing" to disable monitoring.
+
+## Permissions Explained
+- **Read data from the clipboard (`clipboardRead`):** Essential for detecting when you copy text.
+- **Run scripts on tools.7u.pl (`scripting`):** Allows the extension to communicate with the Tools App web page to send clipboard updates.
+- **Storage:** Used to save user preferences (e.g., sound notifications).
+- **Alarms:** Used to keep the background process alive while sniffing is active (to prevent timeout).
+
+## Privacy Policy
+We value your privacy. This extension does not collect, store, or transmit any personal data. Clipboard content is only temporarily read and passed to the local instance of the Tools App running in your browser tab.

+          <h2>1. Introduction</h2>
+          <p>
+            Welcome to Tools App ("we," "our," or "us"). We are committed to protecting your privacy.
+            This Privacy Policy explains how our Chrome Extension ("Tools App Extension") handles your data.
+          </p>
+        </section>
+
+        <section>
+          <h2>2. Data Collection and Usage</h2>
+          <p>
+            The Tools App Extension is designed with privacy as a priority.
+            <strong>We do not collect, store, or transmit any of your personal data to external servers.</strong>
+          </p>
+
+          <h3>Clipboard Data</h3>
+          <p>
+            The extension requires the <code>clipboardRead</code> permission to function.
+            It reads text from your clipboard <strong>only</strong> when you explicitly enable the "Clipboard Sniffer" tool in the Tools App web interface.
+          </p>
+          <ul>
+            <li>Clipboard data is processed locally within your browser.</li>
+            <li>Data is sent directly from the extension to the open Tools App tab via a secure local communication channel.</li>
+            <li>Once you close the tab or stop the tool, the extension stops monitoring the clipboard immediately.</li>
+            <li>We do not have access to your clipboard history, and it is never uploaded to any cloud storage or third-party service.</li>
+          </ul>
+        </section>
+
+        <section>
+          <h2>3. Permissions</h2>
+          <p>The extension requests the following permissions for specific functional purposes:</p>
+          <ul>
+            <li><strong>clipboardRead:</strong> To detect copied text when the Sniffer tool is active.</li>
+            <li><strong>scripting:</strong> To communicate with the Tools App web page.</li>
+            <li><strong>storage:</strong> To save local user preferences (e.g., sound settings).</li>
+            <li><strong>alarms:</strong> To maintain the background process active during monitoring sessions.</li>
+          </ul>
+        </section>
+
+        <section>
+          <h2>4. Third-Party Services</h2>
+          <p>
+            Our extension operates independently and does not use any third-party analytics, tracking scripts, or advertising networks.
+          </p>
+        </section>
+
+        <section>
+          <h2>5. Changes to This Policy</h2>
+          <p>
+            We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
+          </p>

+        <section>
+          <h2>6. Contact Us</h2>
