At DeltaMath Practice, we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect information when you use our website at deltamath.cc.
DeltaMath Practice is designed to work without requiring any personal information. We do not ask you to create an account, provide your name, email address, or any other identifying details. The platform is entirely free and anonymous.
The only data stored is your practice score, which is saved locally in your browser using localStorage. This data never leaves your device and is not transmitted to any server.
Since we do not collect personal information, there is no personal data to use, sell, or share. Your practice scores exist solely on your own device to help you track your progress between sessions.
DeltaMath Practice uses browser localStorage to remember your practice progress between sessions — your score, streak, completed badges, and difficulty preference are stored entirely on your own device. You can clear this data at any time using the Reset button on the practice tool.
Our advertising partner, Google, may set cookies on your browser to display relevant advertisements. These cookies do not personally identify you. You can learn more about how Google uses cookies for advertising at the Google Ads Policy page, and you can opt out of personalized advertising at Google Ad Settings.
DeltaMath Practice uses the following third-party services:
We do not use any other third-party analytics or tracking services. We do not sell, share, or transfer any user data to third parties beyond what is required to display advertisements.
If you are visiting from the European Union, the United Kingdom, or California, you have certain rights regarding your personal data. Because we do not collect personally identifiable information directly, most data rights requests can be addressed by clearing your browser's cookies and localStorage. For advertising-related data held by Google, please use the opt-out links above or visit Google's privacy controls.
DeltaMath Practice is designed for students of all ages. Because we do not collect any personal information, there is no risk of children's data being mishandled. Parents and educators can feel confident allowing students to use the platform.
Our website is served over HTTPS, ensuring that all connections are encrypted. Since no personal data is collected or stored on our servers, there is no database of user information that could be compromised.
You have full control over the only data that exists — your local practice score. You can delete it at any time by clicking the Reset button or by clearing your browser's localStorage.
If we make changes to this Privacy Policy, we will update the "Last updated" date at the top of this page.
If you have questions about this Privacy Policy, you can reach us at contact@deltamath.cc.
