Information about adverts:

Users in EEA countries and the UK

Users in California, USA

  • The BrainBashers website uses Google AdSense for its adverts and to satisfy the requirements of the California Consumer Privacy Act (CCPA) I have enabled restricted data processing for all traffic for users in California via a network control provided by Google. Google will limit how it uses data and will show only non-personalised adverts for any users it detects having a California IP address. Non-personalised adverts are not based on a user's past behaviour.

  • The BrainBashers website uses Google AdSense for its adverts and third party vendors, including Google, use cookies to serve adverts based on a user's previous visits to the BrainBashers website or other websites. Google's use of advertising cookies enables it and its partners to serve adverts to my users based on their visit to the BrainBashers website and/or other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings.

  • The BrainBashers website also uses other third-party vendors and advertising networks to serve adverts. These are certified by Google, and a list of which can be accessed via https://support.google.com/adsense/answer/94149. You may visit any of those websites to opt out of the use of cookies for personalised advertising, if the vendor or advertising network offers this capability.

Google has provided a page entitled "HOW GOOGLE USES INFORMATION FROM SITES OR APPS THAT USE OUR SERVICES" that explains how they use the data that they collect.

Other privacy and cookie information:

Some pages use Google's reCAPTCHA to verify that users are not robots. The reCAPTCHA box ('I am not a robot') has a clickable link to its own privacy policy.

My site also uses server-side ASP session variables to: facilitate various puzzles and games, to count usage, etc. Usually these are automatically destroyed when your session expires.

As with most other websites, my site collects and uses the server's logging information. This information includes details such as your IP address, the browser you used to visit my site, the time you visited my site, and which pages you visited throughout my site, etc. This information might be used for detecting and preventing fraud and unauthorised system access, and ensuring the security of my systems.

Some of the pages automatically post information back to the BrainBashers server in the background, these pages usually inform you of this fact. For example when you complete the alphabet in AtoZ your browser should automatically update the BrainBashers server with your time.

Ticking the box on the "Contact Me" page gives me permission to collect and store your comments, and for me to contact you to reply to your comments. I will only use your email address for this reason. If you would like me to delete any previous comments, then please contact me and I will do so in a timely manner.

I will never sell/transfer/give away/etc any of your personal information to third parties - however I will disclose any required information if legally obligated.
