Duo Apps doesn’t have visitor accounts and doesn’t use analytics, advertising or tracking cookies. This page explains the little data the site does handle.
If you send a message through the contact page, your email address and message are stored so they can be answered by email. They aren’t shared with anyone or added to a mailing list. You can ask for your message to be deleted through the same form.
The site is hosted on Railway and served through Cloudflare. To deliver pages and protect the site from abuse, they process technical request data such as your IP address and browser details, and Cloudflare may set strictly necessary security cookies.
App icons are loaded directly from Apple’s servers, so your browser connects to Apple when it shows them. No referrer is sent with those requests.
Links to the App Store, Apple Newsroom and developer sites take you to sites with their own privacy policies.
This policy may be updated when the site changes how it handles data.
