Cookies and Similar Technologies

Like many websites and applications, we use "cookies" and similar technologies to collect information. A cookie is a small data file that we transfer to your device for record-keeping purposes. We use cookies to enable certain features of the Services, to better understand how you interact with our platform, and to monitor aggregate usage. You can instruct your browser to stop accepting cookies or to prompt you before accepting cookies. If you do not accept cookies, however, you may not be able to use all portions of the Services.

Chrome Extension

The Quantercise Mental Math Chrome Extension is designed with privacy as a core principle:

• All data is stored locally on your device only - nothing is transmitted to our servers
• We do not collect, track, or share any personal information through the extension
• The only permission requested is "storage" to save your preferences and scores locally
• Data stored includes: theme preference, sound setting, best score, and session history (last 20 sessions)
• No analytics, tracking, or network requests are made by the extension
• All stored data can be completely cleared by removing the extension from Chrome

The extension operates entirely offline and independently from your Quantercise account on our website.

Data Security

We are committed to protecting your personal information and have implemented appropriate physical, electronic, and managerial procedures designed to secure your data from unauthorized access and use. However, no method of transmission over the Internet or method of electronic storage is 100% secure.
