> A free and open source fingerprinting service unlike FingerprintJS.
## ⚠️ Important Notice
This library is released under the LGPL-3.0 license and includes ethical guidelines for usage. Please read our [Ethical Contribution Notice](./NOTICE.md) before using this library. We are committed to:
- Transparent data collection
- User privacy protection
- Ethical usage of fingerprinting technology

## About
Fingerprint OSS is a fork of user-info-logger, a simple client-side fingerprinting library that logs user information. Unlike commercial alternatives that are "source available" but not truly open, Fingerprint OSS is released under the LGPL-3.0 license, making it fully open source and free to use.
Fingerprint-OSS is now backed by Cloudflare OSS, Neon, and Netlify.
