Privacy Policy
Effective
This policy covers the Lispex website, documentation and browser Playground operated by HAZE PARK.
Article 1 (Website requests)
The website provides documentation, search, Playground and public downloads.
Vercel receives the requested address, IP address and browser request headers when delivering pages and files.
At entry addresses without a language, the site selects a language using your saved choice, browser language preferences and the country header supplied by Vercel.
Public document, search-index, llms and version files are also delivered through website requests.
Article 2 (Cookies and browser storage)
Selecting a language or theme saves that choice in a cookie. Preference cookies accompany matching requests to this site.
An existing lispex_lang_pref or preferred_lang choice can move to locale, and lispex_theme can move to theme. The migration clears the old cookies it handles, including the retired lispex_lang cookie.
You can manage cookies and saved site data in your browser settings.
- locale cookie
- Remembers your selected en, ko or ru language for one year (31,536,000 seconds) from saving. Opening a language-specific page alone leaves your choice unchanged.
- theme cookie
- Remembers your selected light or dark appearance for one year (31,536,000 seconds) from saving. Without a saved choice, the browser color preference applies.
- sessionStorage locale-position
- Stores the destination path, section, reading position and time during language switching. Restoration removes the entry and accepts positions less than 15 seconds old. An unused entry remains for the tab session.
- localStorage lispex-sicp:draft:{pathname}
- SICP mode saves edited or opened source as a draft for the current page path. It remains until you clear the editor, select an example or remove the site data. Closing the tab can leave the draft available for your next visit.
Article 3 (Work in your browser)
Playground runs code in your browser using WebAssembly modules downloaded from this site. The core editor holds input and results in memory, while SICP mode also saves the draft described above.
Files you select are read and processed in the browser. When you download a generated file, it is saved to your device.
Search matches queries in the browser using document titles or search files downloaded from this site.
Copy buttons write the selected code, link or result to your clipboard.
Article 4 (Downloads and external links)
Downloads request public manifests, release files and checksums from the configured distribution storage through the site. File-size information comes from a public manifest.
The download recommendation uses browser platform information. The requested file address identifies the selected operating system and architecture.
When you run an installation command, the script requests version information, the matching executable and its checksum from the default or selected download address.
Links to release repositories, editor extension stores and other websites send requests to those services when opened. Their privacy information describes their processing.
Article 5 (Public-page visit statistics)
Lispex uses Vercel Web Analytics for public-page visit statistics, including documentation and Playground visits.
Vercel describes anonymous aggregate statistics using a visitor hash derived from incoming requests.
Visit information includes page addresses, dynamic paths, filtered query parameters, referrers, visit times, approximate locations, browser and operating system versions, device types and analytics script versions.
Playground links can carry source in the snippet query parameter. Search in /next places search text in q. Opening or sharing these addresses can send that content in website requests and visit statistics.
Article 6 (Processing providers)
Vercel provides website delivery and visit statistics.
The site delivers its fonts with its own static files.
Hosting and analytics use provider infrastructure that can include overseas processing. Processing locations and retention depend on the service and provider settings.
