You may try aWallet Password Manager, it stores the secure file in local only and has customizable fields. I've been using the paid version since 2014, works excellently. The free version stores the file in local only and the paid version has option to sync with DropBox / Google Drive.

Best way store confidental data is to use open source password manager apps, I personally use KeePassDX for android phones and keepass for Windows OS to store all my sensitive and confidential data.
These app are offline and locally store data in a master password protected database file, so no worry of data leak online.
Best thing about these apps is that the database file is cross platform compatible. i. e, your can open the same database file on your pc too.
If you choose backup the database file to cloud storage regularly, then another advantage is that even if you lose access to your phone, you can always access the data on your pc or other's pc.
Please don't install this. This particular app might be safe but in general keeping card details as wallpaper is safer than installing unknown app from apk
