Privacy Policy
Effective / last updated: 2026-06-25
Brain Games does not send or store your game scores or entered values to a server; every measurement is processed only in your browser.
However, advertising and analytics services such as Google AdSense may use cookies to collect non-personally-identifiable information.
1. Information we collect and do not collect
Brain Games has no sign-up process and does not request or collect information that directly identifies an individual, such as your name or contact details. Game scores and entered values (reaction times, memorized numbers, etc.) are used only within your browser, disappear automatically, and are not sent to or stored on the operator's server.
However, the following information may be automatically generated and collected while you use the website.
- Access IP address, browser type and version, operating system, and visit date and time
- Pages visited, the previous page (referrer), and device information
- Anonymous identifiers via cookies and similar technologies
2. Use of cookies
Brain Games may use cookies to provide the service and display ads. A cookie is a small text file that a website stores in your browser to remember your visit history and settings.
You can refuse or delete cookie storage in your web browser settings. However, blocking cookies may limit some features and ad personalization. Cookie settings can be changed in the settings menu of each browser (Chrome, Safari, Edge, etc.).
3. Google AdSense and third-party ads
Brain Games displays ads through Google AdSense. Third-party ad vendors, including Google, may use cookies to serve personalized ads based on your previous visit history.
- Google uses advertising cookies (such as the DoubleClick cookie) to serve ads based on your visits to this and other sites.
- You can opt out of personalized ads in Google Ads Settings.
- Cookie use by third-party ad vendors can be reviewed and opted out of at www.aboutads.info.
- How Google processes data is explained on the How Google uses data from sites that use its services page.
4. Analytics tools
We may use web analytics tools such as Google Analytics to improve the service. These tools use cookies to collect anonymized statistics such as pages visited and time spent, and do not identify any specific individual.
5. Retention and third-party provision of personal data
Brain Games does not directly collect or store your personal data, so no separate retention period applies. Automatically collected access information and cookie data are processed and retained according to the policies of the respective service providers, such as Google. Except as required by law, the operator does not sell or arbitrarily provide user information to third parties.
6. Your rights
You have the right to refuse information collection through your browser cookie settings, and you can disable personalized ads in Google Ads Settings. For inquiries about personal data handling, please use the contact below.
7. Children's personal data
Brain Games is not primarily intended for children under 14 and does not knowingly collect children's personal data.
8. Changes to this policy
This privacy policy may be revised in line with legal or service changes, and any changes will be announced on this page. For significant changes, the effective date will be updated.
