Technical writing reflects the state of the work and my judgment at the time of publication. I aim for accuracy, but I do not guarantee that every statement will remain correct as software, models, or infrastructure change.

Data controller. Sebastian Kuhn. Contact address at the bottom of this page.

What is collected. With your consent, this site uses PostHog (EU-hosted) to record pseudonymous analytics events: page views, scroll depth, time spent reading, share actions, and reaction counts. IP addresses are not stored. No session recordings, cross-site identifiers, advertising trackers, or profiling are used. Without consent, no analytics data leaves your device.

Legal basis. Analytics processing is based on consent under GDPR Article 6(1)(a) and the Swiss nDSG (Federal Act on Data Protection) Article 31. You may withdraw consent at any time — this does not affect the lawfulness of any processing that occurred before withdrawal.

Processors. PostHog (EU region, data centre in Frankfurt) processes analytics events under a data processing agreement. Vercel provides site infrastructure (US-based, EU data transfer covered by Standard Contractual Clauses).

Retention. Analytics events are retained for 12 months. Consent preferences are stored in your browser's local storage and persist until you change them or clear your browser data.

Your rights. Under GDPR and the Swiss nDSG you have the right to: access personal data held about you; request correction or deletion; restrict or object to processing; and receive your data in a portable format. To exercise these rights, contact me at the address below. Requests will be handled within 30 days.

Supervisory authority. You may lodge a complaint with the Swiss Federal Data Protection and Information Commissioner (FDPIC) or, if you are in the EU, with the data protection authority in your member state.
