Read without sharing your skin history.

Cu Fieldnotes does not ask for your medical history, photos or payment information. The contact form requests your name and email address so we can respond. It has no account, patient intake, or checkout form. Do not send personal health information through this publication.

Interactive controls

The fieldnote search, label lens, comparison selection, and text-size control run in your browser. They do not submit entered search text or selections to a server, and this site does not save them as a profile. A full reload resets the Pocket Fieldnote selections. Its download is generated locally as a text file, and printing uses your browser’s print controls. Other controls may also reset on reload.

Hosting and routine requests

Loading the website requires ordinary network requests. Hosting and DNS providers can process technical information such as IP addresses and request metadata under their own policies. This publication does not promise that infrastructure processing is absent.

External destinations

CoreAge promotional links carry UTM referral parameters identifying the site and article or placement. They do not contain a health answer or a name. Once you visit an external site, that destination’s privacy practices apply, including any medical intake or purchase process it operates.

Source links also open third-party websites. Read the destination’s policy before supplying personal information. Our commercial disclosure explains the promotional relationship.

No optional trackers added

This site uses PostHog for usage analytics and Meta Pixel for page-view and advertising measurement. These services receive page URLs, browser and device information, IP addresses, identifiers and interaction data, and may use cookies or browser storage. PostHog is configured to create profiles for anonymous visitors. Meta may associate visits with a Meta account. Browser settings and blocking tools can limit collection. That statement concerns this site’s implementation, not every external destination or hosting-provider operation.
