Questions
Is Coinfold free?
Yes, and there is no account to create. It shows a banner at the top of Home and Reports, and now and then a full-screen ad after you save a few entries, never while you type.
Does it connect to my bank?
No. Coinfold is a notebook for your own spending: you type what you spend and earn. It never asks for bank details and can't move money.
Where is my data kept?
On your phone. If backup is turned on in your phone's settings, Android can include Coinfold in your own Google account backup so it comes back on a new phone. You can also export everything to a CSV file.
Which currencies does it support?
It follows your phone's currency by default, and you can pick another in Settings, including the rupee, dollar, euro, pound, dong, rupiah, real and many more.
Can I make my own categories?
Yes. There are 16 ready categories, and you can add your own with a name and an icon, rename them or delete them. Entries from a deleted category move to Other.
Which phones and languages does it support?
Android 8.0 or newer, phones and tablets. The app is in English, Spanish, Portuguese, Hindi, Vietnamese and Indonesian.
