Privacy policy
This site has no analytics, no tracking, no advertising, no cookies, and no third-party resources of any kind. What follows is the short list of what is left.
Data controller
Section titled “Data controller”The controller responsible for the data processing described here is:
Ricardas Kauneckas, reachable by email at ricardas@kauneckas.dev.
The full postal address is given in the legal notice.
Hosting
Section titled “Hosting”This website is hosted by Netlify, Inc. (San Francisco, USA). When you visit the site, Netlify automatically processes technical access data that your browser transmits, in particular: IP address, date and time of the request, the page requested, the referring URL, browser type, and operating system. This data is required to technically deliver and secure the website.
The legal basis is Art. 6(1)(f) GDPR (legitimate interest in a secure, functioning website).
As Netlify is a US company, this data may be processed outside the EU/EEA. For details, see Netlify’s own privacy policy.
This is the only processing of your data that happens on a server. Everything below happens on your own device.
The playground
Section titled “The playground”The playground scores code you paste into it. It does this entirely inside your browser: the analyser is the same Rust engine as the command-line tool, compiled to WebAssembly and downloaded once as a static file from this site.
Code you paste is never transmitted anywhere. It is not sent to this site, to Netlify, or to any other service. It is not stored, and it is gone when you close the tab. Analysing it triggers no network request at all: the only thing the playground downloads is the WebAssembly module, once, before you type anything.
Search
Section titled “Search”Site search is served by Pagefind, which builds a static index at build time. Your search terms are matched in your browser against index files downloaded from this site. Nothing you type into the search box is sent to a server or recorded.
The typefaces used here are downloaded from this website, not from a font CDN. No request, and therefore no IP address, reaches a third party such as Google Fonts when a page loads.
Local storage and cookies
Section titled “Local storage and cookies”This website sets no cookies. Two small values are kept by your browser, and neither is ever transmitted to a server:
starlight-themein local storage records whether you chose the light or dark theme. It is written only if you use the theme switch, and it persists until you clear it.sl-sidebar-statein session storage records which navigation sections you expanded, so the sidebar looks the same as you move between pages. It is discarded when you close the tab.
You can delete both at any time through your browser’s settings.
External links
Section titled “External links”This website links to external, third-party sites in several places, for example GitHub, npm, crates.io, and the Visual Studio Marketplace. Clicking such a link takes you directly to that provider; no data is transmitted from this website in the process. From that point on, only that provider’s own privacy policy applies.
Your rights
Section titled “Your rights”Where the legal requirements are met, you have the right to access (Art. 15 GDPR), rectification (Art. 16 GDPR), erasure (Art. 17 GDPR), restriction of processing (Art. 18 GDPR), data portability (Art. 20 GDPR), and objection to processing based on Art. 6(1)(f) GDPR (Art. 21 GDPR).
An informal message to the email address given above is enough to exercise any of these rights.
Right to complain
Section titled “Right to complain”You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the member state of your habitual residence, your place of work, or the place of the alleged infringement.
Changes
Section titled “Changes”This privacy policy is updated as needed, for example when the website or the underlying legal requirements change. The version published here is always the current one.
