Plain Flags is aimed at software development teams.
A private installation of Plain Flags can store users' email addresses in the database.
These email addresses are presumed to be the property of the organization who operates the Plain Flags instance.
They are not meant to be personal email addresses of individual users.
If your team leader requests your personal email address for the purpose of operating Plain Flags, you must request deletion of your account, should you wish to do so, from your team leader or any user with admin privileges.
The public demo installation of Plain Flags does not require any real personal information from users.
