Cookieless Revenue Analytics
Revenue tracking
without a single cookie.
Most analytics tools are cookieless but blind to revenue. Most attribution tools need cookies. Attrifast is the only tool with a cookie-free architecture that connects every Stripe payment to its traffic source — 100% visitor coverage, no third-party cookies, no fingerprinting.

Cookie-free attribution architecture
Here is exactly what happens — from the moment a visitor lands to the moment a payment is attributed — without a single cookie touching their browser.
1
Visitor lands on page
The 4 KB Attrifast script loads. No cookies are set.
▼
2
First-party ID generated
A random first-party ID is generated and stored in localStorage. It is created on your site, never shared across sites, and contains no personal data.
▼
3
Visit recorded with source data
Source, UTM parameters, page URL, referrer, and timestamp are stored alongside the first-party ID — server-side.
▼
4
Stripe webhook fires on payment
When the visitor completes a purchase, your payment provider sends a webhook to Attrifast instantly.
▼
5
Server-side match links payment to session
Attrifast correlates the payment webhook with the session's first-party ID. No client-side cookie needed for the join.
▼
6
Attribution recorded in your dashboard
Revenue is attributed to the original channel, campaign, and page. RPV, conversion rate, and revenue by source update immediately.
What IS stored
- ✓Random first-party ID (localStorage, no personal data)
- ✓Traffic source & UTM parameters
- ✓Page URL visited
- ✓Timestamp
- ✓Payment amount (from webhook)
What is NOT stored
- ✗IP address
- ✗Device fingerprint
- ✗Browser or OS details
- ✗Any personal data or PII
- ✗Cookies (none, ever)
What data is collected — and what isn't
Cookieless does not mean data-free. It means the data collected is aggregated, anonymous, and never tied to an individual. Here is a precise breakdown.
Session data
Collected
A random first-party ID stored in localStorage. Generated on your site, never shared with third parties, and contains no personal data.
Not collected
Third-party identifiers, cross-site tracking, user IDs, login state.
Traffic source data
Collected
Referrer URL, UTM source, UTM medium, UTM campaign, UTM content, UTM term. Stored with the session hash.
Not collected
Click IDs (gclid, fbclid), ad account data, third-party data.
Page data
Collected
Page URL, visit timestamp, number of pages visited per session.
Not collected
Scroll depth, mouse movements, keystrokes, form contents.
Payment data
Collected
Payment amount, currency, and timestamp — received via Stripe webhook. Linked server-side to the session hash.
Not collected
Card details, billing address, customer email, customer name.
Server-side matching explained
The key to cookie-free revenue attribution is the server-side match. Here is how it works without putting anything in the visitor's browser.
Step 1 — The visitor session is registered server-side
When the Attrifast script runs, it sends a lightweight event to our servers. We record the first-party ID, source, UTM data, and page URL. The only thing in the visitor's browser is that random ID in localStorage — no cookies.
Step 2 — The payment webhook arrives
When a visitor completes a Stripe charge, the payment provider sends a webhook to Attrifast. This webhook contains the payment amount, currency, and a customer reference.
Step 3 — The join happens entirely on our servers
Attrifast matches the payment event to the session that was active at checkout time. The match uses the first-party ID and your site's session context — no cookie, no client-side join.
Why this is more reliable than cookie-based attribution
Cookie-based tools can lose the attribution link if the visitor clears cookies, switches browsers, or blocks cookies via ITP or an ad blocker. Server-side matching is immune to all of these. The session exists on your server, not in the visitor's browser.

How to set up cookie-free revenue tracking
No developer needed. No tag manager to configure. No data processing agreement to sign. Up and running in under two minutes.
1
Add the 4 KB script to your site
Paste one line of HTML before the closing </head> tag on every page. The script is 4 KB, loads asynchronously, and sets zero cookies. Works on any website — static, WordPress, Webflow, Next.js, or custom.
<script defer src="https://cdn.attrifast.com/attrifast.js" data-site="YOUR_SITE_ID"></script>2
Connect Stripe
In your Attrifast dashboard, click "Connect Stripe" and paste a restricted API key from your Stripe dashboard. Attrifast registers a webhook endpoint with your payment provider. The key is scoped to read-only access and can be revoked in Stripe at any time.
3
See revenue by channel — instantly
As soon as a payment comes in, Attrifast matches it to the originating session and updates your dashboard. Revenue by source, UTM campaign, and landing page appears in real time. No sampling, no processing delay.
Browser compatibility
Cookie-free tracking is not a workaround — it is a design decision that makes Attrifast immune to browser restrictions that are breaking cookie-based tools.
Safari (ITP)
Full coverageSafari's Intelligent Tracking Prevention blocks third-party cookies and limits first-party cookies to 7 days. Since Attrifast uses no cookies, ITP has zero effect on data accuracy.
Firefox (ETP)
Full coverageFirefox's Enhanced Tracking Protection blocks known trackers. Attrifast does not appear in any tracker blocklists because it does not track individuals.
Chrome (cookie deprecation)
Full coverageChrome completed third-party cookie deprecation. Attrifast has never relied on third-party cookies — first-party or otherwise. No migration needed.
Ad blockers (uBlock, Brave)
Mostly unaffectedSome aggressive ad blockers block all analytics scripts. Attrifast's privacy-first design means it is not included in most blocklists, so impact is minimal compared to GA4.
Cookieless analytics FAQ
How cookieless revenue tracking works, GDPR implications, and accuracy vs cookie-based GA4.
How does cookieless revenue tracking actually work?
Attrifast uses a random first-party ID stored in localStorage, server-side referrer enrichment, and Stripe webhook joins instead of cross-site cookies. A visitor lands on your site, Attrifast records the session under that ID, and when a Stripe payment occurs, the payment event is joined back to the originating channel server-side. No cookie is involved at any point.
Why is cookieless tracking more accurate than GA4 in 2026?
Cookie-based analytics lose 30–60% of conversions to ad blockers (~40% global desktop), iOS/Safari ITP cookie expiry (7 days), and consent banners rejected by users (40–60% in the EU). Cookieless first-party tracking captures those visits because it does not depend on third-party cookies or cross-site tracking.
Is cookieless analytics GDPR compliant without a cookie banner?
Attrifast is built to keep the privacy surface as small as possible: no third-party cookies, no fingerprinting, no PII collected, no cross-site tracking — the only thing stored in the browser is a random first-party ID in localStorage. Consent requirements depend on your jurisdiction and how you deploy analytics, so review your setup with your own counsel rather than relying on a vendor claim.
Can I still attribute multi-touch journeys without cookies?
Yes — but with honesty about the tradeoff. Attrifast handles single-session attribution perfectly. For multi-session journeys, it uses first-party identifiers (Stripe customer ID at payment) to stitch sessions back together, which works for most SMB SaaS and e-commerce flows. It cannot do 90-day deterministic cross-device journeys without consent, but neither can post-cookie GA4.
Does Attrifast work with ad blockers?
Yes. Attrifast can be deployed via a first-party endpoint (subdomain proxy) which bypasses most ad blockers. This recovers the 30–40% of analytics traffic that traditional GA4 / Mixpanel scripts lose to uBlock Origin, Brave, and DuckDuckGo by default.
How is cookieless different from server-side analytics?
Server-side analytics moves data collection from the browser to your server, often still using cookies for user identity. Cookieless analytics removes the cookie dependency entirely — identity comes from a random first-party ID in localStorage plus first-party signals (referrer, Stripe payment). Attrifast combines both: server-side enrichment + zero cookies.
