Cookies last for 14 days.

If a potential customer does not sign-up within that time, the cookie will expire and you will not be credited with any sort of conversion (obviously).

Additionally, if someone signs-up within the 14-day period, but does not begin testing in 14 days, you still may receive commission. As long as they start using Ezoic at some time in the future, you will receive 3% of their Ezoic earnings, no matter how long it takes for them to get started!
