What counts as cancellation
Cancellation can happen by disconnecting the funding account, disabling roundup participation, or closing the account entirely. That gives donors more than one exit path depending on how complete they want the change to be.
Why prospective timing is normal
Like pause and skip controls, cancellation does not affect withdrawals already authorized and in process before the change becomes effective. That is operationally important because payment instructions may already be underway.
What to review after canceling
Review the dashboard or account records to confirm the next cycle is no longer active, and keep an eye on any notices tied to the most recent authorized cycle if you canceled close to the cutoff.
