Cookie Policy
Last updated: 15 September 2026
Cookies and similar technologies (localStorage, pixels) store or read information on your device. EU ePrivacy rules require prior consent for any that are not strictly necessary to provide the service you asked for. This page describes how the X-Lab staff sign-in page uses them.
X-Lab Systems operates this staff sign-in page. Cookies listed here are used to run sign-in, keep it secure, and — only with your consent — measure usage or advertising. Laboratory records processed inside LIMS are handled on the laboratory’s instructions and are not governed by this cookie notice.
Strictly necessary cookies (security, consent record, language, and theme) rely on ePrivacy Article 5(3) (information strictly necessary) and GDPR Article 6(1)(f) or 6(1)(b). Analytics and marketing cookies are set only after GDPR Article 6(1)(a) consent. You can refuse or withdraw as easily as you accept. A choice is stored for 12 months, then asked again.
If Google Tag Manager is configured on this page, it loads Google’s Consent Mode v2 with analytics and ads storage denied until you opt in. Google tags then wait or run cookieless pings. This login origin does not load a GTM container unless one is configured separately. reCAPTCHA on the sign-in page is a security control and is treated as essential.
Essential — always on: sign-in page, reCAPTCHA (when enabled), consent record, language, theme. Analytics — optional: Google Tag Manager / Google Analytics audience and usage measurement if such tags are present. Marketing — optional: Google advertising storage, ad user data, and ad personalization if such tags are present.

Use Cookie settings on this page or on the sign-in screen. Rejecting analytics and marketing does not block sign-in. You can also delete site data in the browser. Blocking essential storage may prevent language or theme restore.
If cookie purposes change, the stored consent version is invalidated and the banner is shown again. The date at the top of this page is the last editorial update.
We use essential cookies to run X-Lab staff sign-in. Analytics and marketing cookies are used only if you agree. You can accept all, reject optional cookies, or choose categories. Rejecting optional cookies does not block sign-in. Cookie policy
