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 consent banner required.
Free to start. No consent banner needed.
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.
- ✓Session hash (non-persistent, non-identifying)
- ✓Traffic source & UTM parameters
- ✓Page URL visited
- ✓Timestamp
- ✓Payment amount (from webhook)
- ✗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.
A short-lived session hash. Valid for the duration of the visit only. Cannot be re-linked to the same visitor on a future visit.
Persistent identifiers, cross-visit tracking, user IDs, login state.
Referrer URL, UTM source, UTM medium, UTM campaign, UTM content, UTM term. Stored with the session hash.
Click IDs (gclid, fbclid), ad account data, third-party data.
Page URL, visit timestamp, number of pages visited per session.
Scroll depth, mouse movements, keystrokes, form contents.
Payment amount, currency, and timestamp — received via Stripe webhook. Linked server-side to the session hash.
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 session hash, source, UTM data, and page URL. Nothing is written to the visitor's browser storage.
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 timing and your site's session context — no cookie, no browser storage, 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 cookie consent configuration. No data processing agreement to sign. Up and running in under two minutes.
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>Connect Stripe
In your Attrifast dashboard, click "Connect Stripe" and follow the OAuth flow. Attrifast registers a webhook endpoint with your payment provider. No API keys to copy, no manual configuration.
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.
