Ubiq does not store any of your database user credentials or your actual data (either the data in your data sources or data used to populate the charts). Nor does it send any of it to Ubiq.co servers. Your database credentials are stored on your laptop where you setup the ubiq agent.
Ubiq agent which you download to your laptop/desktop connects your laptop to your data on AWS using SSH. It does not send the data in your database to Ubiq.co servers. If you connect to data on your laptop or private network, Ubiq agent keeps the data in your database within your network and does not send it to Ubiq.co servers. No ports are opened in the process.
Ubiq Analytics is hosted on Amazon Web Services. They have world class security practices and host famous companies like Dropbox, Instagram, Quora, etc. Read more about it at http://aws.amazon.com/security/
No need to enable remote access for local databases. Ubiq agent sits on your laptop and has read-only access to your database. It also blocks undesirable queries like insert, delete, drop, etc from coming through.
You set the permissions for every user with access to your account (even control who can view your dashboards). Administrators have full access to their account including user management & billing, creators can create charts & dashboards, and viewers can view dashboards. You are the administrator of your account and can assign project based roles to your team mates.
