well if you set it "publicly", then yes.
who do you want to use it? only admins?
I mean, who do you want to input data? and who to view data?

i would like to create some sort of website where people can create an account and use this componement to manage their finances.

oh, ok. so you need every user to view "only his data", and also be able to add their own categories (only for them) and such. is that right?

in this case you need a bit of code customization for the component.

I'm also interested in that feature so users can make their own management.
Also, does it have language selection? I'll need it in spanish.

Indeed, in my case, only authorized user would have write access to all or specific account, and user would have read only access to a specific account containing its own datas !
Am I clear

PS : I'm french and I'm OK to translate to FR language. I'll attach files when done

yes I understand what you mean. not currently available but we will work on that!
