Last Updated: January 24, 2026

Introduction

Welcome to UltraBox (ultrabox.blog). This Privacy Policy explains how we handle information when you use our online music creation tool. UltraBox is committed to protecting your privacy and being transparent about our data practices.

Information We Collect

Information You Provide

UltraBox operates entirely in your browser. We do not collect, store, or transmit any personal information to our servers. All music creation and editing happens locally on your device.

Automatically Collected Information

We may collect basic technical information through standard web analytics:

• Browser type and version
• Operating system
• Pages visited and time spent
• Referring website
• General geographic location (country/region level)

How We Use Information

Any technical information collected is used solely to:

• Improve the functionality and performance of UltraBox
• Understand how users interact with our tool
• Fix bugs and technical issues
• Analyze usage patterns to enhance user experience

Data Storage

Your music compositions and settings are stored locally in your browser using:

• Local Storage: Saves your preferences and recent songs
• URL Hash: Your song data is encoded in the URL after the # symbol
• Browser Cache: Temporary storage for performance optimization

This data never leaves your device unless you explicitly share a song URL or export your work.

Third-Party Services

UltraBox may use the following third-party services:

• Google Fonts: For typography (subject to Google's privacy policy)
• CDN Services: For loading libraries like jQuery and Select2

These services may collect their own analytics data according to their respective privacy policies.

Cookies and Local Storage

UltraBox uses browser local storage to save your preferences and song recovery data. We do not use tracking cookies for advertising purposes.

Custom Samples and External Content

When you import custom samples via URL, you are responsible for ensuring you have the right to use those audio files. UltraBox does not host, store, or distribute custom samples.

Children's Privacy

UltraBox does not knowingly collect personal information from children under 13. Our service does not require registration or personal information submission.

Data Security

Since UltraBox operates client-side in your browser, your data security depends on:

• Your browser's security features
• Your device's security
• Your network security when accessing the site

We recommend using HTTPS connections and keeping your browser updated.

Your Rights

You have the right to:

• Clear your browser's local storage at any time
• Use browser privacy modes to prevent data storage
• Block third-party scripts if desired
• Request information about any data we may have collected

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. Continued use of UltraBox after changes constitutes acceptance of the updated policy.
