We do not store your passwords.
The passwords are gerenated with the code contained within the web page and the calculations occurr within the users browser web client not on our servers. We do not know what your passwords are. We know how they were calculated and the method is public but this does not provide a method for somebody to calculate your password. The passwords are random and known only to you.
You must keep your sheet of passwords private though.
