Zero-Cookie Telemetry: Tracking Campaign Clicks Without Invading Visitor Privacy

You do not need persistent tracking cookies or canvas fingerprinting to measure marketing campaigns. Here is how we extract clean geographic, device, and referrer insights purely from stateless HTTP headers.

Why Cookie Banners Hurt Your Conversion Rates

You click a link. Before you can read anything, a full-screen consent popup blocks your view, asking you to accept dozens of advertising cookies.

Most people leave immediately. Research shows cookie banners cause 15% to 30% of visitors to bounce before reading a single sentence.

These popups exist because legacy tracking tools plant persistent identifiers on visitor devices. Under EU GDPR, UK PECR, and California CCPA regulations, storing tracking cookies requires explicit opt-in consent.

How TLink Measures Clicks Without Cookies

TLink was built around a simple rule: never store or require cookies to measure clicks.

Instead of tracking people, we record events. When someone clicks a link, their browser sends standard HTTP headers during the redirect:

GET /launch HTTP/2
Host: tlink.bond
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 17_4 like Mac OS X) AppleWebKit/605.1.15
Referer: https://t.co/
CF-IPCountry: US

From these standard headers, our edge server parses:

  • **Country Code:** Extracted directly from CDN edge headers (`CF-IPCountry` or `X-Vercel-IP-Country`).
  • **City Name:** Extracted from CDN edge headers (`X-Vercel-IP-City` or `cf-ipcity`).
  • **Device Category:** Identified as Desktop, Mobile, or Tablet using standard User-Agent strings.
  • **Browser and Operating System:** Identified without intrusive hardware canvas tests.
  • **Referral Source:** Extracted from the HTTP Referer header to credit Twitter, LinkedIn, or newsletters.
  • **Bot Filtering:** Search crawlers and social preview bots (Slack, Discord, Twitterbot) are filtered into a separate bucket so your human click counts remain accurate.

    • What We Deliberately Discard

    To protect visitor privacy completely:

  • **No Full IP Storage:** We do not save raw IP addresses in our analytics database.
  • **No Cross-Site Tracking:** We do not track what visitors do after they reach your website.
  • **No Fingerprinting:** We do not run JavaScript audio, canvas, or font tests.
    • Incoming Request -> Parse Stateless Headers -> Record Event -> Discard Ephemeral IP

    Clean Data Without the Compliance Headaches

    Because TLink short links place zero tracking cookies on your visitors, you never need a consent banner on your redirect path.

    You get the campaign metrics you need to evaluate ad spend while respecting your audience's privacy.
