Device fingerprinting creates a persistent signature based on hardware and rendering characteristics, not stored data that users can delete.

Incognito mode
Hardware-based signatures persist
Private browsing hides nothing from device fingerprinting

Cookie clearing
Device identity unchanged
Clear data all you want. The device signature remains

Publisher FAQ
Common questions about protecting your content and revenue.
When a reader uses incognito mode or clears cookies, traditional metering resets. Our fingerprinting identifies them as the same device regardless, so your "5 free articles" limit applies per device, not per session.
Yes. If 50 different devices are accessing a single "personal" subscription, the fingerprinting will reveal this pattern. You can then enforce concurrent device limits or encourage upgrades to family plans.
No. Fingerprinting is invisible to users and doesn't require any interaction. It simply identifies devices. What you do with that identification (enforce paywalls, personalize content, analyze behavior) is up to you.
The SDK works with any paywall system. You call our API to identify the visitor, receive a persistent ID, and use that ID in your existing paywall logic instead of (or alongside) cookies.
Publishers typically recover 10-30% of previously lost subscription revenue by closing the incognito bypass loophole. For a mid-size publication with $5M annual digital revenue, that represents $500K-$1.5M recovered.
Your content has value.
Every reader who bypasses your paywall values your content but isn't paying. They're not a lost cause; they're an opportunity.
