Yes, website owners are obliged to inform users about cookies and obtain consent to their use, especially analytical and marketing ones, as required by the GDPR and the Telecommunications Law (Article 173). Failure to comply with this obligation may result in high financial penalties (up to EUR 20 million or 4% of turnover) and loss of trust. A transparent notification (banner) and the possibility of user choice (consent, rejection, customization) are required.
