Crumble powers Edge ID, Nostra\'s first-party proxy for supported tracking integrations on your own domain. Help your marketing tools recognize returning shoppers with an implementation matched to your store. Nostra manages setup; browser behavior, consent settings and integration requirements still apply.
Your domain.
Your marketing tools.

Your shoppers come back. Your cookies don't.
When cookies expire or are unavailable, a returning shopper can appear new to a marketing tool. The effect depends on the browser, the cookie and how your integration identifies visitors.
Safari blocks third-party cookies by default. Separately, WebKit describes deletion of script-writeable storage after seven days without user interaction and expiry caps for certain CNAME and IP cloaking configurations.
Measure your existing recognition rate by browser and return interval. Cookie expiry, consent and deletion can all affect the result; there is no single baseline for every store.
Measure the same cohorts after deployment. Compare supported integrations under consistent consent and browser conditions, then test whether improved recognition changes marketing outcomes.
Define the visitor cohort, browser mix, eligible returning visitors and observation window before comparing results. Report cookie persistence separately from visitor recognition and incremental revenue. Use a controlled test where possible.
Discuss a measurement plan with Nostra →First-party tracking. Clear expectations.
Edge ID acts as a first-party proxy for supported integrations. Cookie duration and recognition depend on implementation and browser behavior. First-party delivery alone does not guarantee a particular lifetime.
Help recognize returning shoppers.
Tracking on your own domain
Nostra acts as a server-side first-party proxy for supported integrations. Confirm the cookie-setting method and domain configuration for your deployment. Browser privacy rules still apply.
Returning shoppers, known on arrival
Edge ID is designed to help supported tools recognize returning visitors. Validate recognition timing and performance with your store configuration before relying on it for personalization, testing or flows.
Measure what recognition changes.
A longer-lived cookie is one input to measurement. Test whether it improves recognition, email performance or retargeting outcomes for your business.
Define success before deployment. Keep browser mix, consent settings and attribution windows consistent.
Meta. Google. Klaviyo. Attentive.
Discuss Edge ID coverage for Meta, Google Analytics, Klaviyo, Attentive and Intelligems with Nostra. Confirm the exact cookies, events and deployment requirements for each integration. Edge ID supports identity signals; it does not by itself establish causal attribution or guarantee revenue lift.

What is Edge ID?
Edge ID is Nostra's first-party proxy for supported tracking integrations. Crumble is the cookie agent powering Edge ID. It helps your marketing stack recognize returning shoppers; results depend on the integration and implementation.
Why do my cookies expire so quickly today?
Cookie behavior varies by browser and setting method. Safari blocks third-party cookies by default and applies separate limits to script-writeable storage and certain cloaking configurations. Review WebKit's documentation for the relevant conditions.
Does Edge ID guarantee a two-year cookie lifetime?
No universal cookie lifetime applies across all browsers and configurations. Confirm the supported lifetime for your cookie and deployment. Cookie deletion, blocking, private browsing and consent choices can interrupt recognition.
Which tools does Edge ID work with?
Discuss Meta, Google Analytics, Klaviyo, Attentive and Intelligems with Nostra. Confirm support for the cookies and events you use, along with any configuration requirements, before deployment.
What results should I expect?
Set a baseline for your store and test after deployment. Ask for relevant measured cohorts, browser mix, sample size and observation windows. Cookie persistence, visitor recognition and incremental revenue are different metrics; one does not establish the others.
Does Edge ID replace my attribution platform?
Evaluate Edge ID as an identity-signal component of your marketing stack. Attribution models, reporting and experiments still require appropriate tools and measurement design. Confirm how Edge ID fits your existing setup.
Does this require engineering work?
Nostra manages the deployment. Confirm DNS access, supported integrations, consent configuration and any tagging or code requirements during implementation planning.
Does first-party tracking replace consent controls?
No. A first-party deployment does not replace consent controls or user preferences. Review the implementation with the owner of your consent setup and verify its behavior before launch.
