Chirpsy is a monthly subscription service. We charge your card when you subscribe to our service, and each month the service automatically renews for the next month. The day of the month that you will be billed will match the day of the month that you joined Chirpsy. It will be on the same day of the month each month. If you subscribed at the end of a month and the following month has less days, you will be billed on the last day of that month.
