Terms of use
Updated October 8, 2026
Mozg.ru provides educational content, quizzes, archived results and games. These terms describe website use and interaction with the project administration.
Access and accounts
Some content and quizzes are available without registration. Permanent history, publication, awards and other features may require an account. Guest results remain in the browser session; transfer to an account requires separate confirmation. Protect your account access and report suspicious activity to support.
Participation rules
Do not impersonate others or publish unlawful content or personal information without a valid basis. Spam, bypassing limits, interfering with the website and automated actions creating excessive load are prohibited. Follow the stated competition rules and attempt limits.
Results and games
Quizzes are for interest and self-assessment, not medical, psychological or other professional evaluation. Archived scales and explanations may reflect earlier rules. Game items, injuries, levels and awards are fictional game features. The administration may correct calculation errors and results obtained in violation of rules.
User materials
Submit only content you have permission to use. Submitting material for publication permits the administration to store, review and display it within the stated website feature. It does not transfer copyright for unrelated uses. Contact support regarding authorship, corrections or removal.
Availability and restrictions
The website is evolving; trial features may change or be temporarily unavailable. Continuous operation and error-free service are not guaranteed. The administration may restrict actions or accounts for violations or security risks; contact support about restrictions.
Data and ending use
You can delete your account yourself on the Delete my account page. Access, email, Google and Telegram links, private answers and results, subscriptions and support requests are removed. An inactive system record without your former username, email or sign-in access preserves links in the shared archive, published materials and game history. Backups may retain earlier data until scheduled replacement. Revoking Google access alone does not delete the website account. Contact support about corrections or data handling.
Updates and contact
Current terms and their revision date appear on this page. The administration announces significant changes affecting accounts or data use on the website. Use the contacts below for website or terms questions.
