6. Data Security
We implement reasonable security measures to protect your information. However, no method of transmission over the internet is 100% secure. Our developer tools process data entirely in your browser — no data is sent to our servers when using tools like Hash Generator, Image Resizer, or Color Picker.
7. Children's Privacy
Our brain games section is designed for children, but we do not knowingly collect personal information from children under 13. The games work entirely in the browser without requiring any personal data. If you believe a child has provided us with personal information, please contact us so we can delete it.
Our game pages are tagged as child-directed content in compliance with COPPA. On these pages, personalized advertising and remarketing are fully disabled. Only general, non-behavioral advertisements are displayed.
If you are a parent or guardian and would like to learn more about how we protect children's privacy, or wish to request data deletion, please contact us via email.
8. Third-Party Links
Our website may contain links to external sites. We are not responsible for the privacy practices of these third-party websites. We encourage you to review their privacy policies.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Your continued use of the website after changes constitutes acceptance of the updated policy.
