Consent platform: OneTrust
Tracks your browsing behaviour to build a profile and serve targeted ads before you give consent.
A tag manager loading tracking scripts before the visitor has given consent.
These are fonts, embeds, and other resources loaded from external servers. While they serve a legitimate purpose, they share your visitors' IP addresses with third parties before consent.
Tracking cookies are used to identify and follow users across websites. Under GDPR, these require explicit consent before being set, but on this website they are active immediately.
Services and cookies that comply with GDPR requirements. No consent needed.
Recognised and seen loading before consent, but we did not observe them transmit tracking data, so they are not counted in your score. Worth checking each still respects consent.

sigmaaldrich.com has a GDPR compliance score of 10/100.
A score below 50 indicates serious GDPR compliance failures. Multiple high-severity trackers or advertising scripts load before consent, exposing the website to potential fines of up to €20 million or 4% of annual global turnover under GDPR Article 83.
12 trackers detected loading before user consent:
Legal basis: This violates GDPR Article 6(1)(a), ePrivacy Directive Article 5(3), and CJEU Planet49 (C-673/17). Advertising trackers profile visitors for targeted ads. The CJEU's Planet49 ruling (1 October 2019) confirmed that consent must be active and informed — pre-ticked boxes or implied consent are insufficient. This applies to all cookies and tracking mechanisms used for advertising purposes.
Legal basis: This violates GDPR Article 44, Article 46, and LG München I (Case 3 O 17493/20). Exposing visitor IP addresses to third-party servers — especially outside the EU/EEA — without consent or adequate transfer safeguards violates GDPR's data transfer provisions. The Munich Regional Court confirmed that IP addresses constitute personal data and their transfer requires a legal basis.
This GDPR compliance scan of sigmaaldrich.com was performed by GDPR Scanner, a pre-consent privacy scanning tool. The scan captures all trackers, cookies, and third-party scripts that load before a user clicks any consent button.
Under GDPR (General Data Protection Regulation), websites must obtain explicit consent before processing personal data. Any tracker or cookie that fires before consent is a potential violation of EU privacy law.
A privacy score of 100/100 means the website loads zero trackers and zero tracking cookies before the user gives consent. This is the standard required by GDPR Article 5(1)(a) and Article 7.
Essential cookies (session management, security tokens) and first-party functional cookies do not incur penalties, as they are covered by the legitimate interest legal basis. See an example: playhth.com scores 100/100.
Legal basis: This violates GDPR Article 6(1)(a), ePrivacy Directive Article 5(3), and CNIL Decision SAN-2022-023. Tag managers that actively load tracking scripts before consent enable personal data processing without a legal basis. The CNIL fined Google €150 million in 2022 partly because its tag manager loaded tracking before users could refuse cookies.
Legal basis: This violates GDPR Article 6(1)(a), ePrivacy Directive Article 5(3), and CJEU Planet49 (C-673/17). Advertising trackers profile visitors for targeted ads. The CJEU's Planet49 ruling (1 October 2019) confirmed that consent must be active and informed — pre-ticked boxes or implied consent are insufficient. This applies to all cookies and tracking mechanisms used for advertising purposes.
