Privacy issue with default option should be opt-out

[th0ma5w]

Open source version contains a default (which can indeed be disabled) which links to hosted online services. New users that may not be aware of the implications, namely that published charts will compromise the privacy of the displayed data in a single click, so the default action should be to make this option be opt-in instead of opt-out. Alternatively, a good compromise would be to make the distributed, compiled, and downloadable version of the library have this option as opt-in instead of opt-out. The open source version especially may not be an appropriate place for such an option to be enabled by default.

To disable the option, details can be found here:
