What data we process

The website has no registration, comments or contact forms. You can use it without telling us anything about yourself. Only technical data is processed automatically:

• Visit statistics. For every page view we store: the page address, date and time, browser and operating system, the page you came from and approximate location (country). The IP address is not stored in full: its last part is masked and only an irreversible hash is recorded, from which the address cannot be restored; it is used solely to count unique visitors. The purpose is to understand which materials are read and to plan the website’s work.
• Server and protection logs. The server, Cloudflare and the site protection module record IP addresses and requests in order to detect attacks and technical failures.
• Search queries you type into the site search.
• Cookies — listed and explained on the Cookies page.

We do not collect names, addresses, phone numbers or other details about website visitors, and we do not use the data for advertising or profiling.

Grounds and retention

Technical data is processed to run the website, keep it secure and maintain statistics. Statistics are kept for one year and then deleted automatically; protection logs follow the settings of the respective services.

Who the data is shared with

We do not pass data to third parties and do not sell it. The technical chain involves:

• the hosting provider whose servers host the website;
• Cloudflare — protection and faster delivery of pages; requests to the website pass through this service;
• YouTube (Google) — only if you start the video on the front page yourself; until you press play, no request is sent to Google.

Embedded content and external links

The website links to social networks and other resources. Once you follow such a link, the rules of those websites apply: they may collect data and set their own cookies.

Your rights

Under the Ukrainian Law “On Personal Data Protection” (and the GDPR for visitors from the EU) you have the right to learn what data about you is processed, to request its correction or deletion, and to object to the processing. Write to
