Analytics on this site don't set cookies or write anything to your browser's storage. That's why there's no cookie banner.
The only things ever stored are ones you ask for: your light or dark theme choice, if you change it, and a sign-in cookie if you unlock a password-protected page.
I use PostHog to see how the site is used: which pages are viewed, a few specific clicks (opening a project, the resume, a demo, the code, or a contact link), and anonymous session recordings of how pages are navigated. Anything typed into a form field is masked in those recordings.
Because nothing is stored in your browser, you get a fresh anonymous ID each time a page fully loads. I can't recognise you across visits, and I don't know who you are unless you contact me.
