This is a one-person site run by Andreas Oszkiel (Amsterdam, the Netherlands). It's written to collect as little as possible. If anything here is unclear, email andreas@oszkiel.com.
What I collect
Only what you give me, and only to run the things you asked for:
- Your email address — when you subscribe, sign in, or unlock a members-only piece. It's used to send you the sign-in link, the newsletter, and (if you subscribe) account email. Stored in my own database on Cloudflare.
- Payment details — handled entirely by Polar, my merchant of record. I never see or store your card details; I only receive whether your subscription is active.
- Basic, privacy-friendly analytics — aggregate page views via Cloudflare Web Analytics, which uses no cookies and does not track you across sites or build a profile of you.
Cookies
This site uses a single, strictly-necessary cookie:
oszkiel_session— set only after you click your sign-in link, so the site knows you're logged in. It's essential to a service you explicitly asked for (reading members-only content), HttpOnly, and expires after 60 days. Under GDPR/ePrivacy, strictly-necessary cookies don't require consent — so there's no tracking cookie and no consent wall here.
If I ever add a non-essential cookie (e.g. marketing analytics), I'll add a proper consent banner first.
Who I share it with
Only the processors that make the site work: Cloudflare (hosting + database), Resend (sending the sign-in and newsletter email), and Polar (payments). I don't sell your data or share it for advertising.
Your choices
- Unsubscribe any time via the link in any newsletter email.
- Access, correct, or delete your data — email andreas@oszkiel.com and I'll handle it.
- Sign out to clear the session cookie.
You also have the right to lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
