BookFusion is cool. It also has a calibre plugin so you can upload directly to it if you use Calibre. No idea how they are privacy wise but the sync is perfect across multiple devices and systems. It is not open source but it does what you want and has paid levels. Here’s the link: https://www.bookfusion.com/

Very true. However in the less urban areas there is often well water which varies by jurisdiction from drinkable to toxic (even flammable!) Also some places in the US have water that is unsafe to use even if it was boiled. Usually water is handled on the local level and can be different depending on the local government’s ability, wisdom, and funding.
