made me laugh! wow really? I just try to explain the best way I can but no bad intention.
Sorry for the issues and thanks for reporting, I will investigate it and fix
Yeah Analytics it's free and get a lot of features. Also cookies.
But if you are looking for blog-specific analytics (posts, content performance, SEO, posts per month, words per post, best time to post, etc etc), without cookies (forget to add opt-in and opt-out) and 100% GDPR compliant, then you can try for free Ghostboard
You are right but in this way, comparing to Ghostboard, you will get only analytics about visits (page, device, time, etc.) and missing some specific-blog data like posts per month, SEO, content performance, etc.
1 - Just pasting a line in your Ghost admin > Code Injection
2 - Yes, basically: don't use cookies, don't get personal data or identify personally each visitor and all IPs are anonym (last octet removed).
