Privacy Policy

Your Data Never Leaves Your Browser

Your Data Never Leaves Your Browser

  • All CPAP data processing happens entirely in your browser using JavaScript.
  • Your sleep therapy data (EDF files from your SD card) is never uploaded to any server.
  • Data is stored locally in your browser's IndexedDB. Clearing browser data removes it.
  • No user accounts. No login. No server-side database stores your health information.

What We Do Collect

  • Google Analytics 4: anonymous page visit data (pages viewed, time on site, device type). No health data is included. You can opt out by using a browser ad blocker.
  • Standard web server logs via Vercel: IP address, browser type, pages requested. These are used for security and performance monitoring. No health data.

Affiliate Links

Some insight cards and articles contain Amazon Associates affiliate links (identified by rel="sponsored"). Clicking these links takes you to Amazon.com where Amazon's own privacy policy applies. As an Amazon Associate I earn from qualifying purchases at no extra cost to you.

Google AdSense

We display ads on our article pages via Google AdSense. Google may use cookies and tracking technologies to serve personalized or contextual ads based on your browsing activity. You can manage ad personalization in your Google Ad Settings. Google Analytics and AdSense operate independently and cannot access your imported CPAP data, which exists only in your browser's local storage (IndexedDB). These services track general browsing behavior, not health data.

By visiting cpapclarity.com, page URLs are shared with Google, which may infer health-related interests from the site context. No personal health data (AHI values, therapy data) is included in these URLs.

Ads are loaded only on article pages (/learn/*), not on the Dashboard or History pages.

Cookies

On your first visit, a consent banner asks whether you accept analytics and advertising cookies. Google Analytics and Google AdSense scripts load only after you click Accept. If you decline, no third-party cookies are set.

Your choice is stored in your browser (localStorage) under the key cpapclarity-consent. You can change your choice at any time by clicking "Manage cookies" in the site footer.

Third-Party Services
