// install as an app

Pin qbit404 to your home screen

Install the site as a native-feel app on Android, iOS, Windows, macOS or Linux. Launches instantly, works offline, no telemetry, no third-party cookies.

Your browser does not expose native install. Use the per-platform instructions below.
// What you get
⊞

Standalone launcher icon

Out of the browser. Its own window, no toolbars, no tab clutter.

◌

Offline access

The last visited HTML is served from cache. Downloads and assets stay reachable offline.

⚡

Instant repeat-visit loads

The service worker pre-caches critical resources. Return visits do not hit the network.

↗

Share integration

Appears in the system Share menu on Android. Share a URL and it lands in the contact form, pre-filled.

⌘

Quick shortcuts

Long-press the icon for direct jumps to News, Tools, PQC Toolkit or Contact.

∅

Zero telemetry

Same as the web — no tracking, no third-party cookies, no analytics SDKs.

// service worker

What the service worker does and does not do

  • ✓Caches: public HTML, app CSS/JS, icons, downloads, og.svg.
  • ✗Never cached: /api/*, /admin, /account, login/signup/logout, /set-lang. Those always go through the network.

// Troubleshooting
?The "Install" button does not appear

Your browser needs HTTPS, a valid manifest and an active service worker. All three are present. If you still do not see it, browse a bit first — Chrome requires minimal interaction.

?iOS does not let me install with a button

Apple does not implement the `beforeinstallprompt` event. The only path on iOS is Share → Add to Home Screen.

?I want to uninstall

Android: long-press the icon → "Uninstall". Desktop Chrome/Edge: open the app, menu ⋮ → "Uninstall qbit404". iOS: long-press the icon → "Remove app".
