Traditional tracking is broken
Cookies fail. IP addresses lie. Your visitors are invisible. Device fingerprinting changes everything—identify users through what they can't hide.
1
Cookies blocked
Device signatures persist
40% of users block cookies. Our fingerprints don't rely on stored data.
2
Incognito bypass
Hardware-based identity
Private browsing hides nothing from hardware-level identification.
3
VPN masking
Network-independent
IP changes don't affect device fingerprints. Same device, same ID.

Multi-session tracking
Recognize returning visitors across sessions—even without cookies.
One line of code.
Infinite visibility.
We analyze 67 device characteristics—screen rendering, WebGL signatures, audio processing, hardware profiles—to create a unique fingerprint that persists across sessions, browsers, and network changes.

Power ABM with intent data
Built for compliance
Device identification without the privacy concerns. No personal data exposure and enterprise-grade security.
No PII Exposure
Fingerprints are one-way hashes. They identify devices without revealing any personal or device information.
Anonymized Storage
IP addresses are anonymized before storage. We never store raw identifying data.

Frequently Asked Questions
Everything you need to know about our device fingerprinting technology.
Device fingerprinting is a technique that identifies devices based on their unique characteristics—screen resolution, WebGL renderer, installed fonts, audio processing, and 60+ other signals. Unlike cookies, fingerprints persist across sessions and cannot be easily cleared by users.
Our system achieves 99.5% accuracy in identifying returning visitors. We use weighted similarity algorithms that account for natural drift (browser updates, configuration changes) while minimizing false positives.
Yes. Incognito mode only prevents cookie storage and browsing history—it doesn't change the underlying hardware or browser characteristics we use for fingerprinting. The same device produces the same fingerprint.
Our system is designed with privacy in mind. We don't expose personal data in API responses, IP addresses are anonymized, and you have full control over data retention. The fingerprint is a one-way hash—it cannot be reverse-engineered to reveal device details.
Identification completes in under 50ms on average. The SDK is lightweight (~15KB gzipped) and runs asynchronously, so it never blocks page rendering or impacts user experience.
We analyze 67 device characteristics across 16 categories: screen properties, canvas rendering, WebGL capabilities, audio processing, fonts, navigator properties, timezone, language settings, and more. The combination creates a unique signature.
