usetreno.cz has a GDPR compliance score of 0/100.
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.
14 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 6(1)(a), Article 9 (where sensitive data is captured), and EDPB Guidelines 2/2019. Session recording captures detailed user interactions including keystrokes, mouse movements, and form inputs. The EDPB has clarified that such invasive processing cannot rely on legitimate interest and requires explicit, informed consent. If health or financial data is inadvertently captured, Article 9 special category protections apply.
This GDPR compliance scan of usetreno.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 CJEU Planet49 (C-673/17). Advertising trackers profile visitors for targeted ads.

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. 12 essential/functional cookies were found, which are exempt under legitimate interest.
usetreno.cz has serious GDPR compliance deficiencies with a score of 0/100 and 14 violations detected. Multiple trackers and cookies are loading before user consent, which constitutes a clear breach of the ePrivacy Directive Article 5(3).
This level of non-compliance exposes the website operator to significant regulatory risk. Under GDPR Article 83(5), infringements of the basic principles for processing — including conditions for consent — are subject to administrative fines of up to €20 million or 4% of annual global turnover. Recent enforcement trends show increasing DPA activity across the EU.
