Isn’t .local a mdns auto configured domain? Usually I think you are supposed to choose a different domain for your local DNS zone. But that’s probably not the source of the problem?

From looking at the github, I think you don’t need to/want to host this publicly. It doesn’t automatically get and store your information. It’s more a tool for visualizing and cross referencing your takeout/exported data from a variety of tech platforms. It’s just developed as a web app for ease of UI/cross platform/ locally hostable.

Your ISP knows where you’re going anyway. They don’t need DNS for that. They see all the traffic.
