Before you
head out.
Is this free?
Yes. You can install and use DMZ Codex without an account or subscription.
Is it on the App Store or Google Play?
This version installs directly from your browser. Follow the steps above to add DMZ Codex to your device.
Will I get the latest information?
When connected, pages fetch the latest available content. If an app update is ready, choose Update now when convenient.
Why can’t I see an install button?
Open this page in Safari on iPhone or Chrome on Android, outside private browsing and social apps. Your browser may offer installation in its menu instead. On iPhone, use Share → Add to Home Screen.
Does my progress sync between devices?
There is no account sync. Settings saved by companion tools stay on the device and browser that saved them. An installed app may use separate storage, especially on iPhone.
Does everything work offline?
Recently visited pages may be cached, but installation does not save the entire companion for offline use. New pages, fresh information and uncached images need a connection. Device storage settings can remove offline data.
How do I uninstall it?
Remove DMZ Codex like another Home Screen app. Browser site-data settings control remaining stored website data.
