Privacy

This site is run by Lukas Grigis, based in Switzerland. It collects as little personal data as possible. This page explains what is collected, where it goes, and how long it stays.

Newsletter

Subscribing stores your email address in a database (Amazon DynamoDB, AWS region Frankfurt). Signup is double opt-in: nothing is kept permanently until you click the confirmation link, which expires after 24 hours. Unconfirmed requests are then deleted automatically within a few days and drop out of the database backups within 35 days after that.

Issues are sent through Resend. Every email contains an unsubscribe link; after you unsubscribe, your address is deleted within 30 days and drops out of the database backups within 35 days after that.

Contact form

Messages sent through the contact form (name, email address, message) are forwarded to me as an email via Resend. They are not stored in a database on this site; they live in my mailbox, and I use them only to reply.

Spam protection

Both forms are protected by Cloudflare Turnstile, which processes technical browser data to tell humans from bots. This site stores none of it.

Analytics

The site uses Google Analytics 4 to understand which articles get read. It collects page views and technical data such as browser type and approximate location; Google may process this data on servers in the United States. To recognize a returning browser, Google Analytics sets two first-party cookies, _ga and _ga_N23TPJ3X09, which expire after up to two years.

You can exclude yourself with the Google Analytics opt-out browser add-on (opens in a new tab).

Hosting

The site is served as static files from Amazon S3 via Amazon CloudFront (AWS). Like almost any host, AWS processes technical connection data (such as IP addresses) to deliver the pages.

Links to AI assistants

Article pages offer links that open the article in an external AI assistant. These are ordinary links: nothing is sent until you click, and once you do, that provider's own privacy policy applies. ChatGPT, Claude and Perplexity are trademarks of their respective owners; this site is not affiliated with them.

Your data, your call

You can ask what data exists about you, have it corrected, or have it deleted at any time. Send me a note via the contact form and I will take care of it.
