BalanceBar puts your PayPal account balance
right in your Mac's menu bar, so you can see how much you have at a glance, and it updates the balance on a schedule
that you select. It requires a PayPal Business or Premier account.
BalanceBar uses your PayPal NVP API Username, Password and Signature to authenticate with PayPal and get your current account balance. This information is only stored on your computer and although this information grants access to all PayPal NVP API functions, we only connect to PayPal to get your balance, and nothing else. Additionally, you can revoke BalanceBar's credentials from within your PayPal account at any time.
