Cookie Policy

The cookies and similar technologies Trackfully uses, and how to choose.

Last updated 18 September 2026

This policy covers cookies and similar technologies (such as localStorage) on trackfully.app and in the Trackfully application.

Your choice on this website

When you first visit the website you will see a short banner with two buttons. Until you choose, nothing non-essential is set on your device. Accept turns on the two things listed under "After you accept" below. Reject leaves them off. Your choice is remembered for a year in your browser, and you can change it at any time with the Cookie settings link at the bottom of every page.

Always on: essential

These are needed for the website and the app to work, so they do not require consent under PECR. You can clear them at any time through your browser, which will sign you out.

Cookie Purpose Duration
Supabase auth session (sb-*) Keeps you signed in securely Session / refresh window
Theme preference (theme) Remembers light, dark or system 1 year
Cookie choice (tf-site-consent) Remembers whether you accepted or rejected 1 year

After you accept

Our own attribution. We run the same Trackfully snippet on this website that our customers run on theirs. Before you accept it stores nothing on your device; if you send us a message through a form, it records the page you were on and any campaign parameters in the address, and nothing else. After you accept, it stores a first-party visitor identifier so that a message you send later can be tied to the campaign that first brought you here.

Cookie Purpose Duration
_tf_vid (cookie and localStorage) First-party visitor identifier 1 year
_tf_sid, _tf_ft, _tf_lt, _tf_last (localStorage) Session and first and last campaign touch Session to 1 year

Session analytics (Microsoft Clarity). Clarity records how visitors use the site, such as scrolling, clicks and time on page, so we can see what is confusing and fix it. Recordings mask text you type. Clarity is loaded only after you accept, and only when we have it switched on.

Cookie Purpose Duration
_clck Clarity user identifier and settings 1 year
_clsk Connects page views into one session 1 day
CLID Identifies the first time Clarity saw this browser 1 year
ANONCHK, MR, MUID, SM Microsoft cookies used by Clarity for fraud detection and identity syncing Up to 1 year

Microsoft's own description of these cookies is in the Clarity cookie documentation.

In the app

The signed-in application uses the essential cookies above only. It shows no banner and loads no analytics.

The tracking snippet on customers' websites

Trackfully customers install a first-party tracking snippet on their own websites to attribute their leads. Once the visitor has given consent on that website, the snippet stores a first-party visitor identifier (cookie and localStorage) in the visitor's browser, scoped to the customer's own domain; before consent it stores nothing on the device and only processes details a visitor submits through the site's own forms or chat. It sets no third-party cookies and does not track visitors across unrelated websites.

Responsibility for cookie disclosure and any required consent on a customer's website sits with that customer as data controller. Our documentation tells customers what the snippet stores so they can describe it accurately in their own cookie policies.
