Note:
Trees created in Family Tree Builder software are meant to be synced to a family site and provide you with additional benefits like sharing your tree with your family members and getting Smart Matches with other MyHeritage trees.
If you choose not to sync, there are a lot of features that you won’t be able to fully enjoy within the program, such as Smart Matching, Records Matching, Upcoming Events and Profile page from the Family Site section and more.
Syncing also serves as an online backup of your family tree. In case the tree on your computer becomes corrupt, you can easily download your family tree from your online family site. This is an invaluable part of syncing that protects your hard work.
You can decide to keep your family tree only to yourself and to not sync it to your online family site.
To turn off the sync option, please read the following article: Can I choose not to sync my Family Tree Builder tree with my site?
