How do I change my payment method on the web?

You can add another credit card, debit card or PayPal account to your NumberGuru account. Once logged in, open the “My Account” page from the menu or the dashboard. Click on “Edit account info” at the bottom of the page and select “Edit Payment Info.” Enter the credit or debit card details of the new card or add a new PayPal account to add to your NumberGuru account.

Are you a mobile subscriber? 

If you purchased your NumberGuru subscription through the Apple App Store or Google Play, your subscription is managed by Apple or Google. Apple and Google require that you update your subscription through them.

If you purchased your subscription on another mobile device, check your payment details in the application for more instructions.
