Apologies, Monzo currently doesn't allow OAuth to be used publicly for all users. This website is on hold until that's allowed.

Monzo to YNAB does not store any personally identifiable information on its servers from your Monzo or YNAB account. All Monzo and YNAB tokens processed are immediately deleted after use, and the only token we need to keep for an extended period is encrypted with the AES-128-CBC cipher in a secured MySQL database. No data processed will ever be passed to any third-party.
