You can't technically pause a subscription to a program, but cancelling and resuming works like that on FITR.
When you cancel your program, your subscription is effectively paused, and your account will still retain all your data and past history. Down the line, if you'd like to start again, you simply need to resume the program.
However, if you wish to permanently remove all your data, you will need to delete your account. Deleting your account will erase all stored data, including your account history, and will also delete your Stripe account and its connection.
Here's how to cancel.
