Privacy Policy

What the editor processes, what the website may receive, and what never leaves your device.

Last updated: July 29, 2026
Chunkweave NBT Editor

A browser-local editor for Minecraft Java Edition NBT and region files.

Open a local file
Your Minecraft files stay in your browser.

Chunkweave does not upload, store, or receive the NBT, DAT, region, or schematic files you open in the editor.

1. Scope

This policy applies to the Chunkweave NBT Editor website and its browser-based editing tools. It does not apply to third-party websites linked from the service.

2. Local file processing

Files you select are parsed, edited, and rebuilt locally in your web browser. The current version does not provide accounts, cloud storage, server-side file uploads, or payment processing. Closing the tab clears the active working session from the application.

Downloaded copies are created by your browser. You decide where those files are saved and remain responsible for keeping backups of original worlds.

3. Technical data

Chunkweave is hosted on Railway. Railway may process standard connection and request-log data such as IP address, browser type, requested URL, time, and error information for security, reliability, and abuse prevention.

Google Analytics is enabled only after you permit analytics cookies. It may process device and browser information, approximate location derived from an IP address, pages viewed, interactions, and diagnostic data. You can reject analytics cookies without disabling the editor.

The site currently loads font resources from Google Fonts. Google may receive standard connection data when those resources are requested. Learn more in the Google Privacy Policy.

4. Third-party links

Links to Minecraft, Mojang, Microsoft, Google, or other websites are governed by those services' own terms and privacy practices. Following a link may allow that service to receive normal web request data.

5. Retention and sharing

Chunkweave does not retain or sell Minecraft file contents because the website does not receive them. Railway controls the retention of its infrastructure and request logs under its operational policies. If Google Analytics retention follows the configured Google Analytics retention period and Google's policies. Chunkweave does not sell personal information or use it for cross-context behavioral advertising.

6. Your choices and rights

You can avoid processing a world file by not selecting it. Depending on your location, privacy law may provide rights to request access, correction, deletion, or information about personal data. Because this release has no account system, email [email protected] with enough detail to understand your request without attaching private world files, credentials, or other confidential information.

7. Children's privacy

The service is a general-purpose file utility and is not designed to collect personal information from children. Do not submit personal or confidential information through unrelated public channels.

8. Contact and policy changes

Chunkweave is operated by an independent individual publisher. For privacy, support, or product questions, email [email protected]. Do not attach private world data, credentials, or other sensitive information.

This policy may change as hosting, analytics, accounts, or other features are introduced. The date above identifies the current version.
