This site does not collect any personal information. There are no user accounts, no cookies, no analytics or tracking scripts, and nothing you do while browsing is sent to any server. The only way to reach Dr. Lewis is by email, which uses your own email application and is never handled by this website.
What This Site Does Not Do
- No analytics or visitor tracking (no Google Analytics, no Meta Pixel, or anything similar)
- No cookies
- No accounts, logins, or passwords
- No forms that submit data anywhere — the search bar runs entirely in your browser against a local index; nothing you type is sent anywhere
- No advertising or third-party trackers
What Does Happen
Your browser downloads the page itself, like any website, and loads a couple of fonts from Google Fonts to display the site's typefaces — that request goes to Google, not to CardioLearn, and follows Google's own privacy practices.
If you click "Contact" in the footer, it opens your own email application addressed to feedback@cardiolearn.net. That message is a normal email you choose to send — it is not submitted through this website or stored by it in any way.
External Links
Some pages link to outside resources — for example, a professional society's risk calculator, an FDA guidance page, or a specific home blood pressure monitor. Those sites have their own privacy practices, separate from this one. This policy covers CardioLearn only.
Medical Information, Not Medical Records
Nothing on this site replaces your relationship with your own physician, and this site does not store any information about your personal health, diagnoses, or medications. The printable tools under Resources — like the Symptom & Weight Tracker — are blank templates you fill out and keep yourself; nothing you write on them is ever transmitted to this site.
Changes to This Policy
If this policy ever changes — for example, if analytics are added in the future — this page will be updated and the date below will reflect that.
