Privacy and cookies
Eugene Mischenko operates this personal website from Yerevan, Armenia. For questions about data processing, access, correction or deletion, contact eugene@mischenko.me.
Browsing and enquiries
You can use this site without analytics. The server receives technical information, including an IP address and request details, to deliver pages. When you email me or contact me through Telegram, the information you provide is used to reply and discuss working together. Please omit unnecessary personal or confidential information. Email providers, Telegram and other external websites apply their own data policies.
Basic statistics without identifiers
To improve the website, we maintain our own daily counters of page views, document openings and source categories such as Google or ChatGPT. These counters run before a banner choice and do not place identifiers in cookies or local storage. A small browser request sends only a known page path without query parameters or fragments, a document-opening flag and a source category. The full external referrer URL is not sent.
The database stores only a UTC date, counter key and count. It does not retain IP addresses, device characteristics, precise event times, individual events, visitor identifiers or browsing histories. Sources and pages are aggregated separately and cannot be linked for an individual visitor. Data stays on the site’s server, is not sent to Google or advertising systems, and is deleted after 90 days. Openings include reloads and are not counts of unique people or sessions. This basic measurement does not use browser fingerprinting.
Reject turns off both basic counters and Google Analytics. Basic only keeps the aggregate counters without loading Google. You can also turn basic statistics off using the separate button below. A preference cookie remembers your objection for 180 days; existing aggregate totals contain no information that would let us identify and remove your individual view. We also respect the browser’s Do Not Track and Global Privacy Control signals. The server necessarily receives technical network information to deliver requests, but it is not included in the statistics database.
Google Analytics — with consent
After you select Accept, this site loads Google Analytics 4 to measure visits and interest in its sections. Google receives the page address without query parameters or fragments, its title, the referring site and technical browser and device information. Analytics cookies distinguish browsers and visits. Events do not include your name, email, enquiry text or internal search query.
Before consent and after rejection, Google Analytics does not load. Advertising storage, ad personalization and Google signals are disabled in this site’s code. Google processes the data, potentially outside your country, including in the United States. Google’s documentation explains its service and data transfer mechanisms. Google Privacy Policy · Google Data Processing Terms
Google Analytics is configured to retain event data for 2 months and user data for 14 months, with the user period resetting on new activity. These periods apply to data in Google Analytics and differ from browser cookie lifetimes. Aggregated reports may be kept longer.

Change your choice and exercise your rights
The banner offers an immediate rejection option. Use the button below or the link in the footer to withdraw consent at any time. Withdrawal stops analytics and deletes its cookies from this site. It does not undo processing previously performed with consent. After 180 days the site asks again. Use the email address above to contact me about previously collected data; your rights and ability to contact a supervisory authority depend on applicable law.
