There are two possible routes, and using the wrong one is why people cancel Nintendo Switch Online and still get charged. Check which applies to you first.
This is the step people skip. Nintendo Switch Online can be billed either by Apple (if you subscribed inside an iPhone or iPad app) or by Nintendo Switch Online directly (if you signed up on their website). Only the biller can cancel it.
To check: open Settings → your name → Subscriptions on your iPhone. If Nintendo Switch Online appears there, Apple bills you — use route A. If it does not, use route B.
Go straight to the Nintendo Switch Online cancellation page →
Worth knowing: Nintendo defaults every membership to auto-renew, and the setting lives in your account on the web rather than on the console. Family memberships renew for the whole group at once.
Online play, cloud saves, and the retro game libraries stop at the end of the term. Cloud save data is held for six months, so a lapse is recoverable if you return.
Always confirm it worked. Look for a cancellation email, and re-open the billing page to check the status reads cancelled or "ends on [date]". Then set a calendar reminder for the day after the period ends and check your card statement. A surprising number of cancellations do not take on the first attempt.
Most services have a cheaper tier that people never look at, and several offer a pause instead of a cancellation. If you use Nintendo Switch Online occasionally rather than never, a lower plan or a temporary pause usually beats cancelling and resubscribing at a higher price later.
Recurra keeps your remaining subscriptions in one place and reminds you before each renewal — so the next one does not catch you out. No bank login, no account.
