Hey there! Happy to provide context! Templates are only available to individuals with whom you've shared the template URL. They can see the configuration of your workflow but not the actual data within the table. If you haven't shared the template URL with anyone, then it remains private to your environment. To stop sharing your templates, you can go into your table's sharing settings and select "turn off sharing."
It's important to note that sharing a table as a template does make it publicly available, but only those with the specific sharing link can access it. If you don't distribute the link, the template is effectively just for your use.
