What Is Seoclerks Cookies Policy For Affiliates

I was wondering if seoclerks have a cookie that will store affiliate referals informations in their browser.
Example:

1. I send a visitor to any of seoclerk page with my affiliate link(including service pages, WTB, WTT, Or Just The Homepage)
   
2. The visitor closes the browser without signing up.
   
3. Later the visitor come back with seoclerks.com without my affiliate link and signed up.
   

Will that visitor still be my affiliate?
Will I get commissions if he makes purchase.

I Leant other affiliate networks have this cookies feature. Does seoclerks have one???
