Privacy Policy

Last Updated: December 20, 2025

Overview

G-coder is a browser-based tool that helps you generate 3D printing specifications from G-code files. This Privacy Policy explains how the application handles your data.

TL;DR: We do not collect, store, or transmit any of your data. All processing happens locally in your browser.

Data Collection

G-coder collects ZERO personal data. We do not:

❌ Collect your IP address
❌ Track your usage or sessions
❌ Store G-code files you upload
❌ Store generated specifications
❌ Use cookies or tracking pixels
❌ Share data with third parties
❌ Use analytics or telemetry
❌ Build user profiles
❌ Sell or monetize your data

How Your Data Is Processed

1. File Upload

You select a .gcode file from your computer using your browser’s file picker
The file is read into your browser’s memory only
The file never leaves your device

2. Parsing & Analysis

Your browser runs JavaScript code that:
- Reads the G-code file contents (stored in browser memory)
- Extracts specification comments using pattern matching (regex)
- Calculates print time and filament weight
- Formats the data into Markdown tables
No data is sent to any server during this process

3. Output & Copy/Download

The formatted specifications are displayed in your browser
When you copy to clipboard, your browser’s clipboard API handles it locally
When you download a file, it’s generated and saved by your browser locally
No data is transmitted over the internet

What Is NOT Stored

Your G-code files
Generated specifications
Browser history (beyond your normal browser cache)
Session data (unless you manually enable localStorage in a future version)
Any metadata about your usage

Technical Implementation

G-coder is a 100% client-side application:

No backend server – Everything runs in your browser
No external API calls – The app does not communicate with any remote servers
No dependencies – Pure HTML, CSS, and JavaScript (no third-party libraries)
Open source architecture – The code is available on GitHub for audit

Hosted On

G-coder is hosted on GitHub Pages, which means:

GitHub can see that you visited the app (standard web server logs)
GitHub does not have access to your G-code files or the data you process
GitHub’s privacy policy applies to their hosting service: https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement

Browser-Level Privacy

Your browser may cache:

The G-coder HTML, CSS, and JavaScript files
Your browser history
Any files you download (to your Downloads folder)

These are normal browser functions and fall under your browser’s privacy controls, not G-coder’s.

Clipboard & Downloads

Copy to Clipboard: Uses browser’s native clipboard API. Your copied content stays on your device.
File Download: Your browser downloads a .md file to your local device. G-coder does not receive notification of this action.

Security Practices

What We Do

✅ Serve the app over HTTPS (enforced by GitHub Pages)
✅ Use no external scripts or libraries (reducing attack surface)
✅ Process all data locally (eliminating transmission risks)
✅ Validate file types (only accept .gcode files)

What Attackers Cannot Do

❌ Intercept your G-code files (they never leave your device)
❌ Extract your data from G-coder (no data stored remotely)
❌ Track your usage (no tracking code)
❌ Compromise your data through G-coder (no server to hack)

Your Rights

Access & Deletion

Since we do not collect or store any data about you or your G-code files, there is nothing for us to access, correct, or delete.

Data Portability

Your G-code files and generated specifications remain entirely in your control. You can:

Download specifications as Markdown files
Copy output to any other application
Delete your browser cache to remove any cached files

Right to Know

You have the right to know what happens to your data. This document provides complete transparency.

Third Parties

G-coder does not share data with, sell data to, or use services from third parties for data processing. The only exception is:

GitHub Pages (hosting provider) may see that you accessed the app, but cannot see your G-code or processed data

Changes to This Policy

If we make changes to this Privacy Policy, we will update the “Last Updated” date at the top of this document. Since G-coder does not collect data, major changes are unlikely, but we may clarify or expand this policy.

Legal Compliance

This Privacy Policy is provided in good faith to ensure transparency. G-coder complies with:

GDPR – No personal data is processed
CCPA – No personal data is collected or sold
HIPAA, COPPA, etc. – Not applicable (no personal data collection)

Summary

Your G-code files and data belong to you and stay with you. G-coder is a tool that runs entirely on your device. We do not see, store, or use your data in any way. Your privacy is not compromised by using G-coder.
