N2y
N2y is an online service for syncronizing transaction data from your bank to YNAB. N2y is short for "Nordigen to YNAB", Nordigen was the name of the service N2y use for fetching bank transactions, before it was aquired by GoCardless. Yes, it's a very unimaginary project name.
In order to use the service, you need to login using your Google account and accept the terms of service. N2y only asks Google about your email address (to distinguish you from other users), the other permissions Google lists is a sideeffect of the authentication library used.
