# Cooldown Period - mCaptcha

# Cooldown Period

mCaptcha implements leaky bucket algorithm to measure current traffic levels. Cooldown period specifies the leak or the time after which a visitor addition is decremented.

For instance, if initial traffic level is 0 and a user visits one second later, the traffic level will be incremented to 1. Now, if the cooldown period is set to 30 seconds, the traffic level will be decremented after 30 seconds. So after 30 seconds, the traffic level will go from 1 to 0.

## Easy Mode: Default cooldown#

When configuring mCaptcha in easy Mode, the default cooldown period is set to 30 seconds.
