1. Why we use cookies

KIMFAST uses cookies and similar technologies (local storage, app device identifiers) where they are essential, such as keeping you logged in and preventing fraudulent use, and to improve the service and measure advertising performance.

Essential — login session, security tokens, saving unfinished shipping requests. These cannot be turned off.
Functional — remembering your most recently chosen warehouse, display settings and app prompts you’ve dismissed.
Analytics — which screens are used most and where people leave. Google Analytics, Microsoft Clarity, Ahrefs and KIMFAST’s own records.
Advertising — counting whether people signed up, made a request or paid after seeing an ad. Google Ads, Meta, Naver. May also be used for personalized ads.

3. Third parties

Analytics and advertising cookies are set by Google, Meta, Naver, Microsoft and Ahrefs and are governed by each company’s policies. On payment screens, cookies from our payment processor (KG Inicis) are set. Site traffic passes through a security relay (KISA Cyber Shelter).
