Privacy Policy
The short version
Big Brain Battle is free and ad-supported. We don’t ask you to sign up. We don’t sell your personal data to anyone. Ads on this site may be served by third-party networks that use cookies to show you relevant advertising.
What we store
To prevent duplicate votes, we generate a random identifier and store it in your browser’s localStorage. It’s a string of random characters — not linked to your identity, IP address, or anything else. It lives only in your browser and is never sent to a third party.
If you submit an article, we store the URL and any name, email, or note you optionally provide. We use this only to review your submission — we don’t add you to a mailing list or share it with anyone.
Advertising
Big Brain Battle is funded by advertising. Ads may be served by third-party ad networks. These networks may use cookies and similar technologies to collect information about your browsing activity — on this site and others — to serve you relevant ads.
We do not pass your name, email, or any personal information you provide us to ad networks. If you’d like to opt out of interest-based advertising, visit youronlinechoices.com (EU) or optout.aboutads.info (US).
Cookies
Ad networks and infrastructure providers (Vercel, Supabase) may set cookies as part of their service. Ad cookies are used for interest-based advertising; infrastructure cookies are operational only. You can manage cookie preferences through your browser settings.
Analytics
We may use basic analytics to understand how the site is used (e.g. which articles are popular, how many people vote). This helps us improve the product. We do not tie this data to your identity.
Third-party content
Articles featured on Big Brain Battle link to their original publishers. When you click “Read the original” you leave this site and are subject to the privacy policy of the destination. We don’t track those clicks.
Your rights
If you submitted an article and want your name or email removed from our records, email info@bigbrainbattle.com and we’ll delete it promptly.
Changes to this policy
If anything material changes, we’ll update this page. No surprises.
