(I don’t even know if I really need to add this section, but it won’t harm)
This blog is as basic as it can get, being a statically generated site that just presents the articles I write and commit to GitHub in this repo.
I do however use some third party stuff to help getting this up and running so, a quick list:
I use Netlify to build the blog from the GitHub repo and host it on their servers.
As to what concerns data by this blog’s visitors, as mentioned by Netlify here, the access logs containing the IP addresses are kept for less than 30 days.
Just to know if someone is actually visiting the site (and of course some other insights) I use Google Analytics.
The default setting for data retention currently defaults to 26 months. I only see aggregate data (like number os visitors, visits by time, visitors countries, more stuff like that), everything else is handled by Google.
I have Disqus setup on the blog to allow for comments. When using the comments Disqus will keep some data it needs to handle that, to which I have no control over, but having a Disqus account you can handle it directly with them. I only see the same public facing comments everyone else sees when visiting the blog.
Besides using GitHub to host the projects I usually talk about here, I use it to host some code snippets using the provided widgets, so GitHub might also collect some info on this.
I embed some YouTube videos, some I record and others by third parties. Again, due to using the provided widgets, Google might collect some info regarding this videos.
