As a Pley member, the renewal or billing date is the day you are billed each month. Your billing cycle begins on the date of sign up and will renew on the same day of each month thereafter.
Example if you sign up on July 1st, your next billing renewal date will be August 1st and so on.
This information can be found by signing in to your account then either under "Settings" or "Manage Account"
This will take you to the "Account Settings" page. Current end day: This date is the date your billing cycle ends, this is your renewal date, so this means this is day your subscription will be billed.
Any account changes need to be made at least 24 hours prior to you billing cycle ending to take into effect for the next billing cycle.
