AsterioCat: Cookieless Tracking
In 2025, Google officially postponed its full deprecation of third-party cookies in Chrome. But for most AdTech players, the message is already clear:
We’re heading into a cookieless world, whether Google pulls the trigger or not.
Safari, Firefox and iOS already block third-party tracking by default.
And regulations like GDPR, CCPA, and TCF 2.0 are redefining what’s allowed when it comes to user identity, attribution, and data sharing.
Relying on cookies to measure or optimize campaigns? That’s not just risky, it’s outdated.
What Is AsterioCat?
AsterioCat is a lightweight, privacy-compliant cookieless tracking module that lets you identify users without third-party cookies, enabling true analytics, targeting, and optimization in a post-cookie world.

How AsterioCat Works
Three main things to know about AsterioCat:
- AsterioCat runs client-side and hooks into session data using standard browser APIs.
- It does not interfere with auctions or core page logic.
- It works with any AdTech environment and scales from standalone SSPs to enterprise platforms.
What AsterioCat Does
AsterioCat helps you track and recognize users without setting cookies. All tracking is anonymous. No PII is collected. The module is fully GDPR and CCPA compliant. It:
-
Detects whether a user has visited before using fingerprinting (IP, device, user agent)
1 -
Stores minimal session data in a privacy-compliant way
2 -
Enables frequency capping and behavioral segmentation without relying on IDs
3 -
Detects bots vs real users based on session behavior
4 -
Supports integration with DSP, SSP, DMP, or AdServer setups
5 -
Operates fully without cookies — and doesn’t break auction logic
