Cookies and Analytics

Cookies are small records that a browser stores for a website. The website may save your Russian or English language choice in a cookie. This does not require an account.

Registration and sign-in are disabled in the current version. Previous authentication cookies may remain in your browser but do not provide access to accounts or server saving.

Your FBD program is held in the current tab's memory. Cookies and browser storage are not a program backup: save by downloading a JSON file to your device.

The website uses Yandex Metrica to understand traffic and interactions with pages. When the counter is enabled, analytics loads automatically; the current version has no separate analytics cookie switch or consent banner.

Metrica may process page addresses, referral sources, IP addresses, browser and device characteristics, approximate location, and interaction events. Webvisor interaction recording, click maps, and link tracking are enabled. Visits to the Telegram channel are recorded as an event.

Metrica uses cookies and browser storage for visit identifiers and technical data. For example, _ym_uid distinguishes visitors, _ym_d stores the first visit date, and _ym_isad detects ad blockers. Their selection and duration depend on the counter; Yandex publishes the current list.

Browser settings let you inspect and delete cookies and website data, prevent storage, or restrict third-party cookies. Removing the language setting may stop the website remembering your language choice.

Deleting cookies does not reverse previous data processing or prevent analytics loading on your next visit. To restrict Metrica loading, use browser tracking protection or block requests to Yandex Metrica.

For cookie, analytics, and data processing questions, contact the operator Скопцов Илья Александрович at admin@plcportal.ru. The Personal Data Processing Policy explains enquiry processing and user rights.
