Recognized Today.
Remembered for years.
Edge ID is a cookie agent. It moves tracking onto your own domain as a first-party proxy, stretching cookie life from days to up to two years, so Meta, Google, Klaviyo, and Attentive keep recognizing the shoppers they would otherwise forget. Full service, done for you: no code changes, no engineering lift.

Your shoppers come back. Your cookies don't.
Safari and iOS cap most tracking cookies at days, not months. When a shopper returns after that window, your stack treats them like a stranger: ads re-prospect them, email flows go quiet, and attribution splinters.
Third-party and script-set cookies on Safari and iOS expire in as little as 7 days. Most returning shoppers come back later than that, so the tools you pay for never recognize them.
Recognition drops below 30% within 26 days. Retargeting re-prospects people who already know you, flows miss returning shoppers, and revenue quietly leaks.
90%+ of visitors still recognized after 26 days. Cookies live on your own domain for up to two years, so retargeting, flows, and attribution keep working.
Not a pixel. A cookie agent.
Pixels and scripts get their cookies capped by the browser and die within days. Edge ID is a cookie agent: it sits server-side on your own domain, holds identity first-party for up to two years, and keeps every tool that depends on it in sync.
One agent holds on to every shopper.
Tracking on your own domain
Nostra sits server-side as a first-party proxy, so the cookies your tools rely on are set from your domain instead of a third party's. Browsers treat them as first-party and let them live up to two years.
Returning shoppers, known on arrival
Edge ID identifies returning visitors in real time, without slowing the site down. Personalization, testing, and flows react on the first pageview, not after the fact.
The numbers behind being remembered.
Longer cookie life is not a technicality. It shows up in flow revenue, ad efficiency, and attribution you can trust.
Most tracking cookies die in 7 days. Edge ID sets them first-party, so the shoppers you paid to acquire stay recognized for years, not days.
Meta. Google. Klaviyo. Attentive.

What is Edge ID?
Edge ID is Nostra ai's cookie agent. It acts as a first-party proxy on your own domain, extending cookie lifespans up to two years and keeping returning shoppers recognized by the tools you already run.
Why do my cookies expire so quickly today?
Browser privacy features like Safari's Intelligent Tracking Prevention cap third-party and script-set cookies at as little as 7 days. Shoppers who return after that look brand new to your ads, analytics, and email flows.
Does Edge ID slow down my site?
No. Edge ID identifies returning visitors in real time at the edge, on the same infrastructure that powers Edge Delivery. There is no added script weight on the page.
Which tools does Edge ID work with?
Meta, Google Analytics, Klaviyo, Attentive, and Intelligems today, and it works with any cookie. If an integration is not listed, Nostra adds it for you.
What results should I expect?
Brands see 90%+ of visitors still recognized after 26 days, up to 25% more email flow revenue from personalization and abandonment flows, and up to 35% more efficient retargeting spend.
Does this require engineering work?
No. A DNS-level change puts Edge ID live, and Nostra handles the rest. No SDKs, no re-tagging, no code changes.
Never lose a returning shopper.
One deployment moves your tracking first-party. Cookies last up to two years, attribution holds, and every tool in your stack recognizes the shoppers it used to forget.
