What about to load the "safe file" from an URL?

This would enable to sync over multiple devices and let a backend write the file and do the avg-cost per coin calculation that his consumed by coinfox.co.

Great app BTW! Was looking for something like this for weeks now!

I was thinking about doing just this. The hope was to avoid exposing any personal information. So I prefer it to storing any user data

But, I suppose a password could be required to en/decrypt the URL string

Thanks man!

An elaborate solution is what Keepass2Android provides...

Maybe another option (FTP, Dropbox, ..) would do the trick as well without exposing the data. In addition read and write could be possible.

I'm not native with this JavaScripty-Reacty-thing, but I made a prototype. The data is random and hard-coded in the prototype. In the future, the file could be encrypted and decrypted using the Stanford Javascript Crypto Library. Encryption could be optional.
