How do I cancel Flipster?

I'm curious about the process of canceling my Flipster subscription. Could you please guide me through the steps? I've been using the service for a while, but I'm now looking to discontinue my membership. Is there a specific website or app where I can manage my account and cancel my subscription? Additionally, will I be charged for the remainder of the month if I cancel now, or will my subscription end immediately? I'd appreciate any information you can provide to help me navigate this process.
