Privacy
This is a personal portfolio, not a consumer product with accounts. The site still collects a small amount of data so the pages can be understood and so a hiring manager can send a message. This page is the honest inventory of that data.
Analytics
On the production host work.mariusz.cc, the site loads PostHog (eu.i.posthog.com) after the page load. Analytics is limited to that hostname, uses identified_only person profiles, and is there to understand which work samples and case studies people actually open. Local development and preview hosts do not get this script. There is no advertising pixel and no cross-site retargeting.
Contact inquiries
The contact form collects name, email, optional subject, and message. Those fields are validated, then emailed through Resend to work@mariusz.cc. They are used only to reply to the inquiry. There is no marketing list and no sale of that data. If you want an inquiry deleted, email work@mariusz.cc from the same address you used and say so.
Cookies, logs, and your rights
PostHog may set first-party analytics cookies on the production host. Netlify and the serverless functions keep standard request logs (IP, user agent, path) for security and debugging. Password-protected case studies store a signed cookie only after a correct password so the same browser can return. You can ask what is stored about you, ask for deletion of a contact inquiry, or object to analytics by emailing the address above. This site does not require an account and does not sell personal information.
