The short version.

We don't use advertising or tracking cookies. We count visits to our website with Cloudflare Web Analytics, which uses no cookies at all. We only keep what's needed to sign you in, keep you safe, and remember choices you made yourself. That's why you don't see a cookie banner.

WhatWhoWhyHow long
Sign-in cookie Cookie name – to come us keeps you signed in until you sign out, or 30 days
Security cookie set by Cloudflare Cookie name – to come Cloudflare tells real visitors from automated attacks about 30 minutes
Your own settings stored in your browser (text size, which view, sound on/off, slideshow choices) us, on your device only remembers choices you made until you clear them
Your own words for family members ("My own words") us, on your device only — never sent to us lets you call people what you call them, just for you until you clear them

If you block these, signing in and your saved choices won't work. Nothing here is shared with advertisers.
