Cookies & Tracking

Updated September 24, 2026

The Partner Program uses a small set of first-party cookies for one purpose: to correctly attribute each signup to the partner whose link or coupon brought the customer in. We do not use partner cookies for advertising, ad networks, or cross-site profiling.

Cookies set by the partner program

Name	Purpose	Lifespan
cf_visitor_id	Random number created when someone arrives through a partner link. It ties the link click to the sign-up on the same browser, with no personal data. Removed when you clear cookies.	90 days, sliding
cf_partner_code	Stores the partner reference code from a ?ref=, ?aff=, ?via=, or ?coupon= URL. Last-click wins: a newer partner link overwrites the previous code.	90 days from the latest click
cf_partner_source	Tracks which URL parameter delivered the code (ref / aff / via / coupon) so the audit trail records the right channel.	90 days from the latest click
cf_partner_first	ISO timestamp of when the current partner code was first captured. Used to compute whether the 90-day window is still open at signup time.	90 days from the latest click
cf_partner_landing	The exact landing URL (with the partner parameter) at the moment of capture. Useful for forensic review when a referral is disputed.	90 days from the latest click

Total cookie footprint

Five first-party cookies on cleanerflowpro.com (they also work on partners.cleanerflowpro.com). All are SameSite=Lax and Secure. Four are HttpOnly — only the server reads them; cf_visitor_id is not. They are set only when someone arrives through an active partner link, and never when the browser sends the Global Privacy Control signal.

How long they last

90 days from the most recent click. Every new click on a partner link resets the clock and overwrites the previous reference (last-click attribution).

How to refuse

Block cookies in your browser settings, use private/incognito browsing, or clear cookies for cleanerflowpro.com at any time. The site still works fully — only partner attribution is affected, which simply means no partner gets credit for your signup.

No third-party retargeting

None of these cookies is shared with ad networks or any other company. Only cleanerflowpro.com reads them, for the sole purpose of crediting the right partner.
