From what it claims, it doesn't send any data, and it's stored locally, however, I don't see a reason to keep it anymore, nevertheless, it does look like a safety concern.
What is the name of the extension? I would like to dump the source code of of it to see if it sends data anywhere.
The name of the extension is Fea Keylogger, it mentions that it stores all data locally, or at least I hope it does. It'd be interesting to check if it's actually true or not, make sure to report back when you're done testing.

The extension communicates with the internet, something that "Only saves data locally" shouldn't connect to the internet. They're is also another issue with the extension, it logs specifically logins, not just web pages visited and such. After further analysis, the data that it saves isn't even hashed, meaning that all of your logins are compromised if someone gets the data from your local storage of the extension.
My advice would be to uninstall the extension, reinstall chrome, then change all of your passwords.
Interesting, I remember looking it up to find anything suspicious but couldn't, anyway, good detective work. It logs any kind of text input, it often saved my posts here. Anyway, I've now uninstalled it, since I do not need it anymore and due to the suspicion of it being a security hazard.
On the other hand, do you know any kind of similar software that is safe to use?
I couldn't really recommend any monitoring software for your own machine, but I think you'll be safe enough by pressing WIN + L when you get up to lock your screen, or encrypt your computer files when you leave for a long period of time.
