Overview
QuantArenas is a static research site. We do not require user accounts and we do not collect personal profiles. This policy explains what limited information may be collected through analytics and advertising services, and how that information is used.
Information we collect
We collect aggregate usage data such as page views, device type, and approximate location through privacy focused analytics. We do not collect names, payment data, or direct identifiers. If you contact us by email, we will receive your email address and any content you send.
Cookies and analytics
We use Umami for generic page categories and approved interaction counts. Before sending, the site removes private URL parameters, referrers, user-supplied titles and unapproved event fields. Cloudflare Web Analytics runs only on eligible public static pages, not the personalized app shell. Browser-local saved state is not included in these analytics payloads. Links you choose to share can contain portfolio settings and reach the hosting server when opened; this is not a promise of no network requests.
Advertising
QuantArenas may display ads served by Google AdSense. AdSense may use cookies or device identifiers to show relevant ads and to measure ad performance. You can manage ad personalization in your Google account settings and opt out of interest based ads where available.
Data sharing and retention
We do not sell personal data. We share limited analytics data with our service providers solely to operate and improve the site. Data is retained only as long as needed for analytics and compliance purposes.
Security and contact
We take reasonable steps to protect the site and its data, but no internet service is completely secure. If you have questions about this policy, contact chenpeihao1997@gmail.com.
