🔄 Major Update: All Tools Now 100% Offline capable & Privacy-First!

January 26, 2026 – I've completely overhauled Prism.Tools to be 100% offline-capable and privacy-focused, with significant improvements to multiple tools.

📥 For Users Who Cloned/Downloaded This Repo

If you downloaded Prism.Tools before January 26, 2026, you must update to get the latest version:

Option 1: Git Users (Recommended)

# Navigate to your prism.tools directory
cd /path/to/prism.tools

# Pull the latest changes
git pull origin main

# Verify the folder structure
ls -la lib/               # Should show library files
ls -la lib/license/       # Should show license files
ls -la tools/fonts/       # Should show font files

Option 2: Manual Update

    Backup your current prism.tools folder
    Download the latest release from GitHub
    Replace all files – The folder structure has changed significantly
    Verify the new folders exist:
        /lib/ and /lib/license/
        /tools/fonts/

Option 3: Fresh Install
bash

# Remove old version
rm -rf prism.tools-old

# Clone fresh
git clone https://github.com/blgardner/prism.tools.git

🌐 For GitHub Pages Visitors

If you access via https://blgardner.github.io/prism.tools, you're already using the latest version but be sure to 'Refresh'! Enjoy the improved tools with complete privacy.

🧪 Testing Offline Functionality

To verify everything works offline:

    Download the complete repository
    Disconnect from the internet
    Open index.html in your browser
    Test all tools – they should work normally

Pro tip: Use Chrome's "Application" tab in Developer Tools to verify no network requests are made.
🔒 Privacy-First Philosophy

This update embodies our core principles:

    Your Data, Your Device – Nothing is sent to external servers
    Transparency – All libraries and licenses are included
    Control – You decide where and when to use the tools
    Sustainability – Tools won't break when external services change

🚨 Important Notes for Upgraders
If Tools Don't Work After Update:

    Clear browser cache – Old CDN files might be cached
    Check console errors – Look for missing file errors
    Verify folder structure – Ensure all folders exist as shown above
    Use local server – Some browsers restrict file:// protocol

Running Locally:

For best results, use a local server:
bash

# Python 3
python3 -m http.server

# Node.js
npx serve .

# PHP
php -S localhost:8000

📊 Impact Summary
Metric	Improvement
Privacy	100% client-side processing
Dependencies	0 external CDNs
Offline capability	100% functional
File size	~5MB larger (one-time download)
Load time	50-80% faster (after initial load)

❓ Frequently Asked Questions

Q: Why did you make these changes?
A: To ensure your privacy and provide a reliable, always-available toolset that works regardless of internet connectivity.

Q: What if I don't update my local copy?
A: Old versions will eventually break when CDNs change or shut down. They also send data to third parties. Update is strongly recommended.

Q: Are the fonts and libraries legally included?
A: Yes! All libraries include their original license files in /lib/license/. All fonts are either open source or included with permission.

Q: How do I report issues?
A: Open an issue on GitHub with:
    Browser version
    Error message from console
    Steps to reproduce
