This blog is generated by static blogging software so nothing is stored in any database on my server. There are no logins or passwords and there are no comments. The risk of any of your data being exposed directly via this site is therefore virtually nil.
There are no comments on this site so there are no issues of privacy relating to that.
To be clear, for the purposes of GDPR, I do not hold any personal data about you on my servers. There are log files on the server of course and they will log IP addresses, pages visited, dates, times and such, but every server on the internet does that. The only way I'd get your name, address and other personal data is if you email it to me.
The lack of a back-end database on this site means you’re probably much safer here than you are on other sites that use things like Wordpress to drive them.
