Tracking and privacy

Cookies and cookieless tracking

Attriboo's standard website tracker uses a first-party cookie and local storage to remember a browser. For daily pageview totals without browser storage or visitor identifiers, choose Cookieless in Settings → Privacy & data and publish the c.js code from Setup. Blocking cookies alone does not make this tracker cookieless, because local storage can retain the identifier.

Browser records on a tracked website

Cookie expiry and local-storage lifetime are different. Deleting only the cookie can leave the ID in local storage, and the tracker can use that copy to create the cookie again. Browser exclusions are a reporting control; the tracker may create identifier storage before applying the exclusion, so they are not a replacement for consent controls.

RecordPurposeLifetime
_atb_vid cookieRecognizes a browser. Normally shared across the website's root domain and its subdomains.Up to 365 days, refreshed on page load when the tracker runs; browsers may remove it sooner.
_atb_vid local storageKeeps a copy of the browser ID on the current origin.No built-in expiry. Remains until removed by the site, visitor or browser.
_atb_root test cookieFinds the root domain that accepts a shared cookie when no domain override is supplied.Set briefly and removed during detection; has a 10-second maximum age.
_atb_ignore cookie and local storageRemembers a browser exclusion when the exclusion link is used.Cookie: up to 365 days. Local storage: until removed.
_atb_cart session storage on ShopifyAvoids repeatedly tagging the cart with the same visitor ID in a tab.The tab's session.

What cookieless would change

Cookieless is a description of a particular implementation, not a guarantee of anonymity or compliance. A tool that avoids persistent identifiers generally has less information for connecting a first visit to a sale weeks later. Other identifiers or device access still need their own privacy assessment.

Standard tracking uses t.js and a persistent browser ID. Cookieless tracking uses c.js and stores only a daily pageview total for the website, with no page paths, sources, unique visitors or identity links. Open the Cookieless report from Privacy & data to read those totals. Payment-provider connections can still send customer records separately. Switching modes does not erase earlier data: review existing storage and records, replace the old script, and keep one installation. In WordPress, choose the same measurement mode in the plugin settings. Disabling email capture or third-party cookies alone does not switch modes.
