I have many non-Jewish friends who have used this.  Some complain because others changed their information.  It is a collaborative tree much like Geni and wikitree.  I would suggest either of those as alternatives.  I would also suggest looking into Tribal Pages (if it still exists) or doing a google search for "free hosting".  Then put up your own tree.  I believe that I spent between $30 and $40 for TNG the next generation to run my online tree (https://sarahsgenies.com).  Now I did opt to pay for hosting but there is free hosting out there.   I do have a statement about privacy - I include names but no data for the living - and will make people completely private upon request.  Those people do not even show up in an index or name list or search.
