Cookies and browser storage

Updated 21 October 2026

Cookies set by this site

None. The site application sets no cookies at all: no advertising cookies, no analytics cookies and no session cookies. It embeds no social, video or chat widgets, and the analytics script works without cookies. Cloudflare's hosting security features are separate from the application and may process technical request data or set their own security cookies.

Browser storage

The site writes nothing to local storage or session storage. There is no appearance preference to remember, because the site has a single light appearance and no appearance control. The version checker keeps what you paste in page memory only; it is discarded when you close or reload the page.

One optional local-storage value is read if you have set it yourself: plausible_ignore. When its value is true, no analytics events are sent. The site never creates this value; if you set it, it stays until you remove it or clear the site's browser data.

Page views and OffSeq link clicks

The site sends page views and clicks on OffSeq service and contact links to our self-hosted Plausible service at in.ainalytic.net. Each event contains the public page address, limited campaign parameters, the referring site's origin when available, the event name and the site domain. A link-click event adds only a static destination path and a placement label such as header, hero or checker. Anything typed into the checker is excluded. Neither an analytics cookie nor a persistent visitor identifier is set. The privacy policy explains the processing and your rights.

Measurement preferences

The site respects the browser Do Not Track and Global Privacy Control signals, and sends nothing when either is present. Measurement is also disabled for previews, local development and recognised automation.

php2shell.eu is maintained by the OffSeq security team. It is not affiliated with the PHP project, the PHP Foundation or any of the research teams that disclosed these vulnerabilities.

The guidance here summarises public advisories as they stood on the date shown. It is not a substitute for the PHP security advisories or your vendor's own notices, and it cannot tell you whether a particular server has been compromised.
