Trakt is free to use with a standard account, for as long as you'd like. We also offer an optional VIP membership which unlocks a lot of awesome features. Read about VIP's features and please contact us if you have any questions.
You're also able to review your payment history and update your credit card on the VIP page.
If you still want to cancel, you can do so on the same page using the Cancel Your VIP link, circled in yellow in the image below.
*Please note that your VIP features will continue until the year you've paid for is over. This is really just cancelling the automatic annual renewal.
