Privacy Policy

Last updated: January 2026

Introduction

LithoBulb ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website and tool. LithoBulb is completely free to use with no ads, no restrictions, and no data collection.

Information We Collect

We do not collect any personal information. LithoBulb is designed to work entirely in your browser without sending your data to any servers.

When you use LithoBulb:

  • Images and designs: All images you upload and designs you create are processed entirely in your browser. They are never sent to our servers or any third-party services.
  • No user accounts: We do not require registration, login, or any personal information to use the tool.
  • No analytics: We do not use analytics services, tracking pixels, or any tools that monitor your usage.
  • No cookies for tracking: We do not use cookies or similar technologies to track your activity.

How We Use Your Information

Since we do not collect any information, there is no data to use, share, or sell. All processing happens locally:

  • Image editing and collage creation happens in your browser
  • STL file generation happens locally in your browser (web version) or on your computer (desktop app)
  • PNG export happens in your browser
  • No data is transmitted to our servers or any third parties

Local Storage

LithoBulb may use your browser's LocalStorage to store temporary preferences and application state (such as your current design session). This data:

  • Stays on your device and is never transmitted to us
  • Can be cleared at any time through your browser settings
  • Is used only to improve your experience within a single session

You can clear this data at any time by clearing your browser's local storage or using your browser's privacy settings.

Third-Party Services

We do not use any third-party advertising, analytics, or tracking services. Our website is free of ads and tracking scripts.

The only external link on our site is an optional Venmo donation link. If you choose to donate via Venmo:

  • You will be redirected to Venmo's website (venmo.com)
  • Any information you provide to Venmo is subject to Venmo's privacy policy
  • We do not receive or process any payment information
  • Donations are completely optional and do not affect access to any features

Data Storage

We do not store any of your data on our servers. All processing happens locally:

  • Images you upload are processed in your browser's memory
  • Designs you create exist only in your browser session
  • STL files are generated locally in your browser (web version) or on your computer using native code (desktop app)
  • Exported PNG and STL files are saved to your device, not to our servers

Whether you use the website or desktop application, STL generation happens entirely on your device. The web version uses a browser-based port of the STL generator, while the desktop app uses native code. In both cases, no data is sent to external servers during this process.

Your Privacy Rights

Since we do not collect, store, or process any personal information, there is no data to access, correct, or delete. However, you have full control over:

  • Your browser's local storage (which you can clear at any time)
  • Any files you download or export from the tool
  • Your browser's privacy settings and cookie preferences

Cookies

We do not use cookies for tracking or advertising. Our website does not set any cookies that collect personal information or track your activity across other websites.

If your browser's local storage is used, it is only for temporary application state and can be cleared at any time through your browser settings.

Children's Privacy

LithoBulb is designed to be safe for users of all ages. Since we do not collect any personal information, we do not knowingly collect information from children under 13 (or the applicable age in your jurisdiction).
