First-party tracking that survives Safari, iOS and adblockers.
Serve your tracking from a subdomain you own. Cookies become first-party, ITP can’t truncate them, and attribution stays intact — even in 2026’s privacy-first browsers.
Third-party cookies are dying and you’re losing attribution you don’t even know about.
Safari caps third-party cookies at 7 days (ITP). Firefox blocks them entirely (ETP). Chrome is phasing them out. If your affiliate tracking runs on a third-party domain, you’re losing between 15% and 40% of attribution depending on your audience.
- Safari ITP truncates cookies to 7 days
- Firefox ETP blocks third-party tracking
- Chrome moving to cookieless by 2025–2026
- iOS intelligent tracking prevention hides referrers
- Cookies set as first-party on your subdomain
- No 7-day ITP truncation
- Full referrer preserved
- Works identically across all browsers
Your subdomain, our edge. Cookies that last.
Point a DNS CNAME from track.yourbrand.com to our edge. Our servers serve your tracking, SSL is automatic, and the browser treats every cookie as first-party.
3rd-party cookie
Three DNS records. Done forever.
Pick a subdomain
track.yourbrand.com, go.yourbrand.com — any subdomain you don’t already use.
Add a CNAME record
Point it to the Traaaction edge endpoint. SSL is provisioned automatically.
Flip the switch
Update your short link domain and the middleware does the rest. Existing links stay valid.
Built for a cookieless future.
ITP safe
Cookies are first-party, so Safari’s 7-day truncation doesn’t apply to your tracking.
Cross-browser
Works identically on Safari, Firefox, Brave and Chrome — no browser-specific fallback needed.
Recover attribution
Typical gain: +15–40% more attributed conversions depending on your Safari/iOS audience.

Frequently asked questions
What is a CNAME record and why does it matter?+
A CNAME record is a DNS alias — "track.yourbrand.com" points to our edge server. Since the browser sees your domain, any cookie set is first-party and escapes tracking prevention.
Does my main website need to change?+
No. Only the subdomain for tracking (e.g., track.yourbrand.com). Your www.yourbrand.com is untouched.
How long does DNS propagation take?+
Usually 5–30 minutes. We monitor the CNAME and notify you the moment it’s live.
Is SSL handled automatically?+
Yes. We issue and renew Let’s Encrypt certificates for your subdomain through Vercel. Nothing to configure.
Do existing short links keep working?+
Yes. Both the default domain and your new custom domain resolve to the same clicks. We strongly recommend migrating all new links to custom domain.
Does it help with adblockers?+
Partially. Most adblockers target known third-party trackers. First-party domains aren’t in their block lists, so your tracking survives on more browsers.
