TL;DR: We don't collect, store, or track your files. All conversions happen in your browser. We respect your privacy completely.
1. Introduction
Welcome to MRPACK to ZIP Converter ("we," "our," or "us"). This Privacy Policy explains how we handle information when you use our website at mrpacktozip.blog (the "Service").
2. Information We Do NOT Collect
We want to be crystal clear about what we don't do:
- We do NOT collect your MRPACK files: All file conversions happen entirely in your browser using JavaScript. Your files never leave your computer.
- We do NOT store converted ZIP files: Generated ZIP files are created locally in your browser and downloaded directly to your device.
- We do NOT track your conversions: We don't log which modpacks you convert or how often you use our service.
- We do NOT require registration: You can use our service completely anonymously without creating an account.
- We do NOT use cookies for tracking: We don't use tracking cookies or similar technologies.
3. How Our Service Works
Our MRPACK to ZIP converter operates entirely client-side:
- You upload a .mrpack file or provide a Modrinth project ID/URL
- Your browser downloads the necessary files from Modrinth's servers
- JavaScript code in your browser processes and converts the files
- The converted ZIP file is generated locally and downloaded to your device
- No data is sent to our servers during this process
4. Third-Party Services
Our service interacts with the following third-party services:
4.1 Modrinth API
When you convert a modpack, your browser makes requests directly to Modrinth's API (api.modrinth.com) to fetch modpack metadata and download mod files. These requests are subject to Modrinth's privacy policy and terms of service.
4.2 CDN Services
Mod files are downloaded from various CDN services (such as Modrinth's CDN) directly by your browser. We have no control over these services.
5. Server Logs
Our web hosting provider may collect standard server logs, which may include:
- IP addresses
- Browser type and version
- Pages visited
- Date and time of access
- Referring website
These logs are used solely for technical purposes (security, performance monitoring) and are not used for tracking individual users.
6. Data Security
Since we don't collect or store your files, there's no risk of your modpack data being compromised through our service. However, we recommend:
- Only download modpacks from trusted sources
- Keep your browser and operating system updated
- Use HTTPS connections (our site uses HTTPS)
7. Children's Privacy
Our service does not knowingly collect information from children under 13. Since we don't collect personal information at all, our service can be used by anyone. However, we recommend parental supervision for younger users.
8. Your Rights
Since we don't collect personal data, there's no data to access, modify, or delete. You have complete control over your files at all times.
9. CORS and External Downloads
Due to browser security restrictions (CORS), some mod files hosted on external servers may not download automatically. In these cases:
- Your browser may open new tabs to download files directly from the source
- You may need to manually download certain files
- This is a browser security feature, not a limitation of our service
10. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify users of any material changes by updating the "Last Updated" date at the top of this policy.

Summary: We built this tool with privacy as a core principle. Your files stay on your computer, and we don't track what you do. It's that simple.
