Family Tree Privacy

I am currently looking at the free version of Genopro as I am aware that even a "private" FTM tree is searchable via Ancestry. However, unless I have mis-read the Genopro information it appears that the tree will still be searchable via the internet unless it is password protected and that the tree can only be password protected if a Registration Key (ie the sofware) is purchased. I just want to have a family tree where I can record all my information for my own use and to pass on to my children without having to exclude living relatives etc. Is any tree software secure?

 

In relation to this I would suggest that nobody uses the classic 'mother's maiden name' as as a security word. Similarly when you are asked to set up a security question, go for 'favourite holiday destination' rather than 'place of birth' or 'father's middle name'. While I think it unlikely that anyone will make the effort to try to break into my bank accounts, etc. I am pretty certain that it would be trivial for someone to find out all those bits of info.
(and if you regularly post holiday pics on the web, probably your favourite destination is not hard to find...

 

I don't know if this is relevant, as I only use Ancestry for my tree. I have used my Gx2 paternal grandfather as the home person and made virtually everyone in the generations after that as private, their info is kept in my working spreadsheet. This has certainly reduced some of the nonsense messages I would get and those I do get are now only from the dim and distant past ancestors which have in some instances proved fruitful.
