Act No. 18/2018 Coll. on Personal Data Protection
Slovakia applies this national law alongside the GDPR. The summary below concentrates on the national overlay so that the GDPR baseline is not duplicated.
Status: Binding Slov-Lex time version effective 18 August 2026, incorporating Act No. 168/2026 Coll.
Citation: Act No. 18/2018 Coll., especially ss. 15, 44-46 and 78-79
Regulator: Office for Personal Data Protection of the Slovak Republic
Source basis: Official binding Slov-Lex PDF effective 18 August 2026 and official regulator English reference downloaded and cross-checked on 23 August 2026.
How the national law fits with GDPR
The Act supplements the GDPR, contains rules for processing outside the GDPR and law-enforcement processing, and regulates the Slovak supervisory authority, national processing situations and enforcement.
National additions and variations
- Section 15 retains 16 as the age for consent-based information-society services and requires reasonable efforts to verify consent or authorisation by a legal representative below 16.
- Section 44 requires publication of the DPO contact details and communication of those details to the Slovak Office.
- Section 78 permits limited employment-contact disclosures necessary for work tasks, but disclosure must not violate the employee's respectability, dignity or security.
- Section 78 limits use of a generally applicable identifier to necessity, requires explicit consent where consent is the basis and generally prohibits publication unless the person published it.
- Sections 78 and 79 add rules for expression, third-party collection, research safeguards, international security standards and continuing confidentiality obligations.
The legally binding PDF is Slovak. The regulator's English translation was used only as a reading aid and predates the 18 August 2026 consolidation; each cited requirement was checked in the current Slovak PDF.
Operational approach
First maintain the GDPR control set. Then document whether this country is in scope and apply the national controls to the affected people, systems and processing. Keep article-level evidence for child consent, employment, special-category or criminal data, research, electronic communications, identifiers, surveillance and any rights restriction relied upon.
Do not treat GDPR compliance as automatic compliance with Act 18/2018. Record the national trigger, the responsible owner, the local procedure and the current official source reviewed.
