2. What data we collect and why

We collect various types of data to provide and improve our Service.

2.1. Data you provide directly to us

This information includes your IP address, browser type, internet service provider, entry/exit pages, timestamps, and data about your actions on the site. We use this data for security, trend analysis, and Service administration.
  • Cookies and analytics: We use cookies and similar technologies to maintain sessions, save your preferences, and collect analytics information. We use third-party analytics services:
    • Google Analytics: Helps us understand how users interact with our site. Data may be transferred to Google servers in the USA. Google processes this data in accordance with its Privacy Policy. We use EU Standard Contractual Clauses (SCCs) to ensure adequate protection of your data when transferred to the USA. You can opt out of Google Analytics data collection by installing a special browser extension: Google Analytics Opt-out Browser Add-on.
    • Yandex.Metrika: Also used to analyze user behavior on the site. Yandex processes this data in accordance with its Privacy Policy. Data is processed in compliance with Russian Federal Law "On Personal Data" No. 152-FZ.

  • With your consent (voluntary consent): When using analytics services (Google Analytics, Yandex.Metrika), we request your consent via a cookie banner. You can withdraw this consent at any time through the Cookie Settings page. Withdrawal of consent does not affect the lawfulness of processing based on consent before its withdrawal.

We do not sell your personal data. We may share it only with the following categories of third parties:

  • Service providers: Companies that help us manage our business, such as hosting providers, analytics service providers (Google, Yandex), and authentication services (when using OAuth). We enter into agreements with them guaranteeing data protection in accordance with GDPR.
  • Law enforcement: We may disclose your information if required by law or in response to a valid request from government authorities.
  • Data transfer outside the EU: Some data (e.g., data collected through Google Analytics) may be transferred to countries outside the European Union, including the USA. We use EU Standard Contractual Clauses to ensure adequate protection of your data during such transfers.
