Hyros's current methodology, which it calls AI Swarm Data, combines six signals: first-party live data, first-party historic data, third-party data, network-wide attribution patterns, device fingerprinting, and predictive AI algorithms. Device fingerprinting, sometimes called print tracking, is the piece this page focuses on: every device that visits your site leaves a distinct set of signals that Hyros combines into a unique identifier, then uses to stitch together a visitor's full journey across multiple sessions without relying on cookies. It is one input among six, not the whole system.
Hyros tracking operates in two distinct phases. The first builds a device fingerprint the moment a visitor lands on your site. The second anchors that fingerprint to a real person the moment they submit first-party data. Together they create a continuous record from the first ad click to the final revenue event. Print tracking is the foundation of our full Hyros implementation service.
When a visitor lands on your website, the Hyros tracking script fires and collects browser and device signals. These signals are combined to create a unique fingerprint for that visitor.
What makes fingerprinting durable is that these signals come from hardware and software configuration, not cookies or local storage. The fingerprint survives incognito mode, cookie deletion, and browser data clearing because the underlying device has not changed. A visitor who clears their cookies and returns the next day is still identifiable to Hyros through their fingerprint.

The fingerprint alone identifies a device. It does not yet tell Hyros who the person is or how to connect them to downstream events in your CRM, phone system, or payment processor.
That changes the moment a visitor submits first-party data. When someone fills out a form, enters a phone number, or provides an email address, Hyros creates a lead record.
From that moment forward, the first-party identifier becomes the anchor for every subsequent event in the buying journey. A lead calling in is matched to their phone number. A lead progressing through your CRM is matched to their email. A transaction is matched to whichever identifier was on file at the time of purchase.
Every session that Hyros tracks stores the click data that brought that visitor to your site. For organic visits this includes the referral source and landing page. For paid traffic this includes the click ID.
The click ID is the critical element for offline conversion sync. When Google serves an ad and a user clicks it, Google appends a gclid parameter to the destination URL. Meta appends an fbclid. Microsoft Ads appends an msclkid. Hyros captures these parameters from the URL at the moment of the click and stores them in the session record.
When that visitor later converts, whether immediately on the same session or weeks later after multiple sessions, the stored click ID is available to include in the offline conversion payload sent back to the ad platform. That is what allows Google and Meta to credit the specific ad, campaign, and keyword that started the journey. How Hyros offline conversion sync works →
| Platform | Parameter | Used for |
|---|---|---|
| Google Ads | gclid | Offline conversion sync to Google |
| Meta Ads | fbclid | Offline conversion sync to Meta |
| Microsoft Ads | msclkid | Offline conversion sync to Microsoft |
A common attribution problem is the visitor who researches on a desktop at work and converts on a mobile device at home. Standard cookie tracking loses that person between devices. Hyros handles it in two ways.
Any action a lead takes in your sales process will be tied to the same email or phone number they provided at opt-in. When that person transacts from a different device, the transaction is matched to the existing lead record via their identifier, regardless of which device completed the purchase.
This also handles household attribution, where one household member opts in and a different member completes the transaction. A CRM field can associate the opted-in identifier to the new contact, preserving the attribution link.
When you send a follow-up email or SMS to a lead, Hyros appends the first-party identifier to the links in that message. When the lead clicks that link on a new device, their browsing session on the new device is immediately associated to their existing lead record.
This resumes the full attribution chain on the new device without requiring the visitor to fill out a form again, a critical capability for businesses with multi-touch, multi-device sales cycles.
The Hyros tracking script needs to fire on every page of your website before any other scripts that might affect page behavior. This ensures the fingerprint is captured before the visitor interacts with any elements that could alter the browser environment. Two common implementation failures prevent lead records from being created correctly. Both are among the first things we check in a gap analysis when a client is not hitting the 70 percent attribution target.
Lead generation accounts trace 95.9% of revenue back to a click. Retail traces 63.9%. The gap is business model, not setup quality. We measured both in our 2026 attribution benchmark.
Ad blockers, browser privacy settings, and certain corporate networks block third-party scripts. When the Hyros script is blocked, the fingerprint is not created and no lead record is generated for that visitor. This directly reduces your attribution percentage.
Solution: implement the Hyros script through a first-party proxy on your own domain rather than loading it directly from Hyros servers.
When your lead capture form is embedded via an iframe from a third-party platform, the Hyros script running on your main page cannot read the first-party data being entered in the form. Hyros cannot create a lead record from data it cannot access.
Solution: move the form out of the iframe, implement a direct API call to Hyros from your form submission handler, or use a server-side integration to post the lead data to Hyros after submission.
The practical difference between the two approaches comes down to where the record lives and what can destroy it.
| Scenario | Cookie tracking | Hyros print tracking |
|---|---|---|
| Visitor clears cookies | Tracking history lost | Fingerprint reconstructed on return visit |
| Visitor uses incognito mode | No cookie created | Fingerprint still generated from device signals |
| Visitor switches browsers | Prior browser cookie unavailable | Matched via first-party identifier if opted in |
| Visitor converts on different device | Attribution chain broken | Matched via CRM identifier or email/SMS link |
| Long consideration period (30+ days) | Cookie may expire before conversion | Lead record persists indefinitely |
The practical result is that Hyros captures attribution data for conversions that cookie-based platforms would lose. This represents a meaningful share of total conversions, particularly in industries where users are privacy-conscious or where long consideration periods make cookie expiration a real factor.

Yes. Hyros uses browser fingerprinting rather than cookies as its primary identification method. The fingerprint is built from hardware and software signals including canvas rendering output, WebGL parameters, screen resolution, and IP address. It survives cookie deletion, incognito mode, and browser data clearing because none of those actions change the underlying device configuration.
If the Hyros script is blocked by an ad blocker or corporate network, no fingerprint is created and no lead record is generated for that visitor. That visit drops out of your attribution entirely. The fix is to load the Hyros script through a first-party proxy on your own domain, which prevents ad blockers from identifying and blocking it as a third-party script.
The connection happens at the moment a visitor submits first-party data. When someone fills out a form or provides a phone number, Hyros creates a lead record that contains both their identifier and the complete click history of every prior session tied to that device fingerprint. From that point, any downstream CRM event associated with that email or phone number is automatically linked back to the originating ad click.
No. When a form is embedded via an iframe from a third-party platform, the Hyros script running on your main page cannot access the data being entered inside the iframe. The result is that form submissions through iframes do not create lead records in Hyros. The solution is to move the form out of the iframe, use a direct API call to Hyros on form submission, or implement a server-side integration.
Through two mechanisms. First, any transaction matched to a lead's email or phone number is attributed back to their original lead record regardless of which device completed the purchase. Second, when Hyros appends a first-party identifier to email or SMS follow-up links, clicking that link on a new device immediately resumes the attribution chain without requiring the visitor to fill out a form again.
