You can delete your Tariffic account directly from within the app. Go to Account > Delete account .
Please note that a remaining balance will be lost after deletion.
If you no longer have access to the app, please send us a deletion request including your registered phone number using our contact form.
We will need some sort of proof that you are the owner of the account (phone number). Therefore please add your PayPal address used for topping up your account in the past or add a phone number you have called through Tariffic recently.
