Privacy Policy
Last updated: August 2026. The short version: we collect almost nothing, and your scores never leave your device.
1. Who We Are
CortexCrunch (cortexcrunch.com) is operated by Boum Ltd, an independent private limited company registered in the United Kingdom. For any data protection inquiries, you can reach us via our contact page or email admin@boum.ltd.
2. What We Collect and Store
No User Accounts: CortexCrunch requires no registration, password, or profile creation. We do not collect names, phone numbers, or account credentials to access our games and tools.
Local Device Storage (Client-Side Only): Your benchmark scores, session history, streaks, and settings (e.g. sound and dark mode preferences) are stored strictly in your web browser's localStorage. This data remains on your physical device and is never sent to our servers. You can permanently erase all stored scores at any time by clearing your browser's site data.
3. Cookies and Third-Party Advertising
CortexCrunch is supported by web advertising through Google AdSense to ensure all 28 games remain 100% free for everyone. Google and its certified advertising partners may use cookies or device identifiers to serve ads based on your visits to this and other websites across the internet.
- You can manage or opt out of personalised advertising via Google Ads Settings.
- To learn how Google processes data across partner sites, visit Google Partner Technologies.
- You can also opt out of third-party interest-based ad networks at aboutads.info.
EEA / UK Consent Management: For visitors from the UK, European Economic Area (EEA), and Switzerland, we deploy a Google-certified Consent Management Platform (CMP). You can freely accept or reject personalised advertising cookies upon entering the site.
4. Children's Privacy
CortexCrunch is designed for a general audience and does not knowingly collect personal identifiable information from children under the age of 13.
5. Your Rights Under UK GDPR
Because we do not maintain accounts or store identifiable personal data on server databases, there is no personal profiling associated with your identity on our backend. For ad-related cookie choices, use the Google settings outlined above. If you have any questions or data requests, please contact us.
6. Changes to This Policy
Any updates to this policy will be posted on this page with an updated timestamp.
