To opt out of Shop Pay, enter your mobile number in the opt-out form, and then tap Submit request. If you're paying for an order using Shop Pay Installments, then you can opt out after your payments are complete.
Opting out of Shop Pay means that your phone number and stored data will be deleted, and you won’t receive verification codes by SMS. You can still use Shop to track your orders and follow stores.
If you don’t want to use Shop to track your orders anymore, then you can delete your Shop account.
