I am not affiliated, associated, or in any way officially connected with YNAB, or any of its subsidiaries or its affiliates. I am a fan of YNAB and wanted to supplement the YNAB experience by providing additional insights into spending habits. The official YNAB website can be found at https://www.ynab.com. The names YNAB and You Need A Budget as well as related names, marks, emblems and images are registered trademarks of YNAB.
In order to gain access to your budgets and transactions data from the YNAB servers, Cents uses OAuth over a secure HTTPS connection in compliance with the YNAB API. The login page for YNAB will be presented to you within the app, where you can use your credentials to provide Cents access to your YNAB data. Cents then stores an access token locally on your device, which is only valid in combination with a key provided by YNAB that is unique to Cents. This unique key is stored on a private server and not accessible to anyone else.
