Nope! Your account will remain active up until your next scheduled billing date, and you'll have until that date to use any remaining credits left on your account. 

For example, if you are billed on the 20th of each month and request cancellation on November 1st, your last date to use your MoviePass credits would be on November 19th.

Another option, besides cancelling, is to pause your account.  You can pause your account for two months, twice a year, simply by clicking on the “account” icon on the app (lower right corner), clicking on “subscriptions” and then clicking “pause”.  While your account is paused you can still use any available credits.  This is a great option if you just want to take a break, or if you know some great movies are on the horizon.

See you at the movies!
