01 / Scope
Who operates this website
This website is operated by Mateusz Chrzanowski. For privacy-related questions, the contact address is mc@mateuszchrzanowski.com.
The website is designed as a public professional and publishing site. It does not provide user accounts, advertising profiles or behavioural marketing services.
02 / Cookies & storage
What is stored on your device
The website uses a minimal first-party cookie model. No analytics cookie is created by this website.
Cloudflare may set strictly necessary network or security cookies if an enabled Cloudflare feature requires them. These are used to deliver or protect the service, not by this website for advertising or behavioural profiling.
| Name | Purpose | Category | Retention |
|---|---|---|---|
archestral_privacy_v1 | Remembers your storage selection so the website does not ask again on every visit. | Essential | 12 months |
archestral_intro_seen | Remembers that the opening sequence has already been shown and prevents it replaying on later visits. | Preference / optional | 180 days |
The optional intro cookie is created when you explicitly select Remember intro. It tells the website not to replay the opening sequence on future visits from this browser. If you select Essential only, the intro cookie is removed.
03 / Cloudflare analytics
Aggregate traffic measurement
The website is delivered through Cloudflare. Cloudflare processes network and HTTP request metadata as part of delivering, securing and measuring the site. This can include an IP address, requested URL, timestamp, user agent and other request metadata.
Cloudflare zone-level analytics are used for aggregate traffic visibility, including request counts, country-level traffic and Unique Visitors. Cloudflare determines originating country from the IP address associated with a request. Infrastructure-level counts can include ordinary visitors as well as automated crawlers, bots or other services that request site content.
The site also uses Cloudflare Web Analytics for aggregate page and performance statistics such as visits, page views, referrers, country, device type, browser, operating system and Core Web Vitals. Cloudflare Web Analytics is designed without analytics cookies, localStorage identifiers or cross-site user fingerprinting.
These analytics are used to understand overall reach, publication visibility, site performance and traffic patterns. They are not used to build advertising audiences, identify individual visitors for marketing or follow people across unrelated websites.
04 / Public files
Publications and downloads
Publications and other downloadable files may be served from Cloudflare R2. Requests to those public file URLs pass through Cloudflare infrastructure and can therefore form part of infrastructure traffic and security logs or aggregate analytics.
No account is required to read or download public publications from this website.
05 / External services
Links outside this website
The website contains links to external services such as LinkedIn, Amazon and Archestral Lab. A third party receives information only when you choose to follow an external link or otherwise interact with that third-party service. Their own privacy policies then apply.
Cloudflare is the infrastructure provider used to deliver and protect this website. Information about Cloudflare's own data practices is available in the Cloudflare Privacy Policy ↗.
06 / Your choices & rights
Control over the optional preference
You can reopen the privacy controls at any time using Privacy settings in the website footer. Selecting Essential only removes the optional intro-memory cookie. You can also delete cookies directly in your browser.
Where data protection law applies, you may have rights including access, rectification, erasure, restriction, objection and data portability, depending on the circumstances and legal basis. Consent for the optional intro preference can be withdrawn at any time without affecting prior processing.
You may also lodge a complaint with the competent data-protection supervisory authority.
