There are two possible routes, and using the wrong one is why people cancel Google One and still get charged. Check which applies to you first.

This is the step people skip. Google One can be billed either by Apple (if you subscribed inside an iPhone or iPad app) or by Google One 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 Google One appears there, Apple bills you — use route A. If it does not, use route B.
Go straight to the Google One cancellation page →
Worth knowing: If you subscribed via the iOS Google One app it is an Apple subscription — cancel in iPhone Settings instead. Google One storage is shared across Gmail, Drive, and Google Photos, so the free 15 GB has to cover all three.
You drop to 15 GB free. If you are over that, Gmail stops receiving mail and Photos stops backing up after a grace period. Clear space first.
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 Google One occasionally rather than never, a lower plan or a temporary pause usually beats cancelling and resubscribing at a higher price later.
