Semantic-Privacy-Guard is a tool that scans your text to find personal information. It then hides sensitive data before it can leave your company or reach large language models. The software works quietly in the background and handles large files without slowing your computer. It uses a mix of methods like pattern matching, machine learning, and language processing to spot private details.
You do not need to know any programming to use this. It runs on Windows and protects your data in a simple way.
- AI safety and firewall
- Compliance with privacy laws
- Data privacy protection
- Support for EU AI Act and GDPR rules
- Java-based middleware
- Detection and redaction of personal info
- Stream-based, memory-friendly processing
- Use of machine learning and regex
- No extra software required beyond Java
Before you start, make sure your PC has:
- Windows 10 or later
- At least 4 GB of RAM
- 100 MB free disk space
- Java Runtime Environment (JRE) version 11 or newer installed (Get it from java.com)
- A stable internet connection to download the software

Download Semantic-Privacy-Guard
The link takes you to the project’s GitHub page. Look for the Releases section on the right or in the main repository area. This page holds the latest versions of Semantic-Privacy-Guard.
Find the Windows installer file, usually named like Semantic-Privacy-Guard-Setup.exe or similar. Click on it to download.
Once downloaded, open the file by double-clicking it. Follow the simple instructions on the screen:
- Choose your installation folder (the default is usually fine)
- Accept the license terms
- Wait while the program installs
After installation finishes, you will find a new icon on your desktop or in the Start menu:
- Click the Semantic-Privacy-Guard icon to run the program
- The app will open its main window and is ready to use
The application has a simple interface designed for ease of use.
- You can drag and drop large text files or log files into the window
- Or copy-paste text directly into the input area
Press the Scan button. The program begins checking the text. It looks for common types of personal data like:
- Names
- Emails
- Phone numbers
- Addresses
- Identification numbers
This detection happens through patterns, statistical predictions, and language models working together.
The program creates a new version of your text with personal data hidden. It replaces sensitive details with placeholders to keep the meaning but protect privacy.
You can save the redacted file or copy the safe text to use elsewhere. This ensures private information never leaves the company network or goes to large language models vulnerable to leaks.
- Privacy-first: Stops sensitive info before it travels beyond your network.
- Hybrid detection: Uses pattern matching, machine learning, and natural language tools for accuracy.
- Handles large data: Stream processing means it works well with big files without eating memory.
- Easy to use: No programming needed. Simple buttons and clear options.
- Works offline: After download, you can run it without internet.
- Customizable: Options to adjust detection sensitivity and file handling.
- Java-based: Runs on any system with Java, making it flexible.
If the app fails to start, check that Java is installed:
- Open Command Prompt (type
cmdin the search bar) - Enter
java -version
If it does not show a version number, install Java from java.com.
Large files may take some time. To improve performance:
- Close other heavy applications
- Use the stream processing options in settings
- Restart your computer and try again
Make sure the text format is supported (plain text or common logs). If the text format uses unusual encoding, convert it to UTF-8.
Semantic-Privacy-Guard works locally on your computer. Your data does not get sent to external servers. This design helps you meet data privacy rules like GDPR and the EU AI Act. The software processes text right where you run it, reducing risk from leaks or exposure.
Within the app, use the Help menu for more guides and tips.
