Cookies and analytics

We use Google Analytics to understand how visitors use our website. We may also use advertising measurement tools, such as Google Ads conversion tracking and the Meta Pixel, to measure the results of our campaigns. These tools set cookies and collect usage data on our behalf.

Some of these providers process data outside Ukraine, including in the European Union and the United States. Where required, we rely on appropriate safeguards for such transfers. We may also disclose information if required by law.

Data retention and security

We keep inquiry and project data for as long as needed to respond to you and provide our services, and afterwards for the period required by law or to resolve disputes. Analytics data is retained according to the settings of the respective tools.

We protect personal data with access controls, two-factor authentication and encrypted connections. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
