Legal basis: This violates GDPR Article 44 and LG München I (Case 3 O 17493/20, 20 January 2022). Loading fonts from external servers transmits visitor IP addresses to third-party servers, often outside the EU. The Munich Regional Court ruled on 20 January 2022 that embedding Google Fonts without consent violates GDPR, awarding €100 in damages per visitor. Self-hosting fonts eliminates this violation entirely.

This GDPR compliance scan of stem.cz 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 Austrian DSB Decision (DSB-D155.027, 2022). Analytics trackers process personal data such as IP addresses and browsing behaviour. The Austrian Data Protection Authority ruled in January 2022 that Google Analytics use without consent violates GDPR, as data is transferred to the US without adequate safeguards. The ePrivacy Directive requires prior consent for accessing information on a user's device unless strictly necessary.
✓ No tracking cookies detected before consent. 4 essential/functional cookies were found, which are exempt under legitimate interest.

stem.cz should implement a Consent Management Platform (CMP) that blocks all non-essential trackers and cookies until the visitor gives explicit consent. This includes configuring tag managers like Google Tag Manager to use consent-aware triggers, self-hosting external fonts, and auditing all third-party scripts. After making changes, re-scan with GDPR Scanner to verify compliance.
