I don't use tracking cookies on sanderkorf.nl. No banner asking you to accept a pile of trackers. You browse, you read, you leave. That's it.
What cookies are
Cookies are small files a site can store on your device. Some remember a login. Others follow you across the web. I skip the second kind entirely.
Why I skip tracking cookies
Your browsing here is not my business intelligence project. I keep the site fast and readable instead of wiring up ad-tech.
- Privacy: I don't need a trail of every page you opened for marketing.
- Less clutter: No cookie walls or consent pop-ups.
- Focus: I'd rather fix slow pages than tune a tracking pixel.
What I do use
A few privacy-oriented tools help me keep the site fast and handle contact requests. None of them are set up for ad tracking or a marketing profile of you. Like most analytics and security tooling, they can still see technical data (for example coarse location from IP, or browser and device signals) because that is how the service runs. I do not use that to identify you for ads.
Contact form (Convex, Resend, Turnstile)
When you submit the contact form, Convex Inc. stores your inquiry in their database, Resend Inc. sends the notification and acknowledgement emails for me, and Cloudflare Turnstile runs a quick check to keep bots out. Turnstile may set or read cookies or similar storage for that step. Retention and legal bases are in the privacy policy.
Vercel Analytics
Vercel Analytics shows coarse traffic patterns: which pages get views, rough referrers. It is designed to be cookieless and privacy-oriented. It does not set advertising cookies or create a cross-site marketing profile.
Vercel Speed Insights
Vercel Speed Insights flags slow pages so I can fix them. Same idea: no tracking cookies, no ad profile. Performance metrics only.
Both tools are provided by Vercel Inc., which acts as a processor for SDKode Management BV. Hosting and these tools may involve processing outside the EEA (including the United States) under safeguards described in the privacy policy.
Ambient site tint (coarse geo and weather)
Hero, invite, and card film pick up a subtle sky tint from coarse location (Vercel geo headers on the edge, stored as a city/coords cookie, not your IP) and a weather lookup from Open-Meteo (no API key). That only adjusts CSS variables. It does not change page copy.
Ask my writing (blog only)
On /blog and post pages, Ask my writing sends your question through Convex Inc. to Vercel AI Gateway and a capped model. It searches indexed excerpts from my blog posts and portfolio cases only. Do not paste passwords or personal data. Turnstile is not used for this feature unless I add it later for abuse spikes.
What that means for you
- No ad-style tracking cookies on this site
- No cookie consent banner for tracking cookies I don't use
- Fewer third-party scripts than a typical marketing site
- Analytics and performance tools may still process limited technical data as described above
