Privacy at Daufo
Daufo (https://daufo.kr) publishes technical guides on Core Web Vitals and site performance. This page explains what we collect while you read them, and how it’s used.
What We Track and Why
We use standard web analytics — server logs and aggregate visit counts — to see which performance topics readers find useful, so we can prioritize future guides. We don’t collect more than that.
Cookies
Cookies here fall into two buckets: small functional cookies that remember basic preferences, and advertising cookies placed by Google AdSense.
Google AdSense and Ad Personalization
We run ads through Google AdSense. Google may use cookies to personalize ads based on your prior browsing elsewhere. You can review or opt out of this at Google’s Ad Settings: https://www.google.com/settings/ads
We Don’t Sell Your Data
Nothing here is sold to third parties. Anything you share through the contact form is used only to answer that message.
Your Rights
Depending on where you live, you may have rights (for example under GDPR or CCPA) to access, correct, or delete personal data tied to your inquiries. Reach out via Contact to use these.
Children
Daufo is written for developers and site owners, not children, and we don’t knowingly collect data from anyone under 13.
Updates
This page changes as our tools or ad setup change. Last updated: July 2026.
