čTečka is a lifestyle application developed by Ministerstvo zdravotnictví České republiky for Android devices. The program is available for free and falls under the Health & Fitness subcategory. čTečka is primarily designed as a verifier app for the Digital COVID Certificate of the Czech Republic.

The app uses EU technical standards to prove the health status related to COVID-19, including vaccination, recovery, and test results. The program can scan a QR code, verify electronic signatures, and check the validity of the certificate according to Czech Republic validation rules. It can also display summary and detailed information from the certificate. The app operates in compliance with EU and CZ law and facilitates the right of free movement and access to services and events during COVID-19 pandemics.

The application processes data of Digital COVID certificate holders from EU member states for the purpose of checking the certificates by persons accredited by EU regulation, Ministry of Health decrees, or based on a voluntary basis. It doesn't store or send out the personal data nor the health data of checked persons. Overall, čTečka is a reliable and efficient tool for verifying Digital COVID Certificates in the Czech Republic.
