TIP: you will know that any changes/entries input into Keepass have saved once the Asterisk in the window menu dissapears
Example: Data that is not saved which has an asterisk in the title

Once you are sure that database is saved you should delete the downlaoded database on your machine which is probably in Downloads unless you specified a different file path. You can also delete the passwords from your browser as well.
