Two layers, one product.

Chrome, Edge, Brave, or Arc

Chrome blocks one-click installs from outside the Chrome Web Store. Until we’re listed there (in the next few weeks), the install is two taps:

1. 1

   Download the extension

   Download PureGuard.zip (~1.7 MB)

   Unzip it after it downloads — you’ll get a folder called pureguard-extension.

2. 2

   Open the extensions page

   In your address bar, type chrome://extensions and hit enter. (For Edge use edge://extensions, Brave use brave://extensions, Arc use arc://extensions.)

3. 3

   Turn on Developer mode

   Toggle the Developer mode switch in the top-right corner of the page.

4. 4

   Click "Load unpacked" and pick the folder

   Click the Load unpacked button (top-left) and select the pureguard-extension folder you unzipped.

Firefox

Firefox makes this clean. We’re publishing the signed extension to Mozilla’s store right now. Until that lists, here’s the temporary path:

1. 1. Open about:debugging in Firefox.
2. 2. Click This Firefox on the left.
3. 3. Click Load Temporary Add-on and pick manifest.json from the unzipped folder.

Temporary add-ons clear when Firefox restarts. We’ll move to the permanent signed version (one click, persists across restarts) the day Mozilla approves the listing — usually within a week.

iPhone & iPad

Two paths on iOS. The native PureGuard Browser app is in the App Store review queue right now — once it ships, that’s the recommended path. Until then, the home-screen web app gives you the same filtered browsing experience:

Use today: PureGuard as a web app

1. 1. Open Safari (must be Safari, not Chrome) and visit pureguard.ai.
2. 2. Tap the Share button (square with up-arrow).
3. 3. Scroll down and tap Add to Home Screen.
4. 4. Tap Add. PureGuard appears on your home screen like an app.

The home-screen version filters everything inside the PureGuard browser. It does NOT filter the native Instagram or TikTok app — Apple doesn’t allow any app to read another app’s screen. The native PureGuard Browser handles this by giving you a filtered version of Instagram/TikTok/X/Reddit inside our own shell.

Coming soon: native app from the App Store

When the App Store approval lands you’ll get a one-tap install just like any other app. Drop your email on the waitlist and we’ll notify you the day it’s live.

Android

Direct download — no Play Store needed. We’re still building the signed APK; it ships in the next couple days. Drop your email on the waitlist and we’ll send you the download link the moment it’s ready.

When it lands, the install is three taps: tap the download link from this page on your Android phone, tap the file, allow Chrome to install apps from this source one time, then PureGuard installs.

Mac, Windows, and Linux

Native desktop app with system-wide DNS filter and tamper resistance. Building right now — expected this week.

• macOS: .dmg, drag to Applications, open. Apple-signed and notarized so no scary warnings.
• Windows: .msi installer, double-click. Click through the SmartScreen warning the first time.
• Linux: .AppImage (universal) or .deb (Ubuntu/Debian).

Drop your email on the waitlist for your platform — we’ll send the link directly.

Safari (Mac & iPad)

Safari extensions distribute exclusively through the Mac App Store. PureGuard for Safari is in the App Store review queue. Until it’s live, on Mac you can use Chrome / Brave / Arc with our extension; on iPad, the home-screen web app described in the iPhone section works.
