Almost all sites need updates and fresh content. It is naturally the former that we address be it in the arena of features, tech updates or just general advice.
It is however your website and ultimately you are the owner and responsible for its delivery. All web-sites are by their very nature public domain or open source and once `installed` it is entirely your decision as to how much maintenance you decide to employ.
Just a little note about `open source`: we can never stop someone looking at your page-source or the code used to run the site, but we do deploy .htaccess and .env for security so no-one is going to get your data.
