App Repositories

NOTE: F-Droid serves a similar function to the Apple App Store or Google Play store. It contains only free and open source apps. Applications can be browsed, downloaded and installed without the need to register an account.

To install apps, let's download F-Droid, your primary app repository.

If you don't find a privacy-friendly app on F-Droid, Aurora Store is your next stop. It allows you to access Google Play Store anonymously.

  1. Open F-Droid app
  2. Tap the magnifying glass icon in the bottom right corner to begin a search
  3. Type "Aurora Store" and select the app name (subtitle is "by Rahul Kumar Patel")

Install New Apps

TIP: Before installing new apps from F-Droid, sandboxed Google Play Store, or Aurora Store, see our complete list of recommended apps.

Simple Rules to Follow...

  1. Use privacy-friendly apps: There are viable open-source privacy-friendly alternatives to the apps you have previously used.
  2. Stay away from Big Tech: Apps made by Google, Facebook, Microsoft, Apple and other Big Tech corporations should be avoided based on their standard practice of selling your personal data for profit and tracking everything you do.
  3. Install apps from these sources, in this order:
    • F-Droid: The best place to find apps is on F-Droid, a repository that curates privacy-friendly open-source alternative apps.
    • Aurora Store: If you cannot find a solution on F-Droid, the next step is to search Aurora Store, an open source app that connects to Google Play Store anonymously.
    • Direct Download: Not all apps have to be installed using a repository. There are several excellent apps available for download directly from their developer's website.
  4. Sandboxed Google Play Store: If the app you installed complains about not being connected to Google Play Store, ask yourself "Do I honestly need this app?" If the answer is "No", delete it. If the answer is "Yes", you'll need to install the "Sandboxed" version of Google Play Store available in the "Apps" app. Read the instructions at for more detail.

Harden Your Device

  1. Reduce App Dependency: The fewer apps on your phone, the more secure and private it will be. I challenge you to only install what you need. This will increase available storage space and reduce the potential for leaked data through random apps.
  2. Review App Permissions: Apps don't always need the permissions they request. Go to Settings > Apps & notifications > See All ## Apps. Then select each app and review permission settings. Change to Approve, Deny, or Ask Every Time as necessary.
  3. Install a Firewall: Install a firewall like NetGuard from F-Droid to restrict network access on a per-app basis. Once installed, scan through the list of apps and decide whether to restrict network communication. Be cautious of restricting system apps that appear in the list.
  4. Setup Multiple User Profiles: If you must install proprietary (closed source) apps that are questionable in terms of privacy (i.e. for your job), create a "Work" profile and isolate them from your personal data. Learn more.
  5. Activate Private DNS: Why is DNS important? Learn more. Go to Settings > Network & Internet > Advanced > Private DNS. Select Cloudflare DNS, or input a Private DNS provider hostname.
  6. Install a VPN: A virtual private network encrypts the data being sent from your device by tunneling to a VPN server, effectively cloaking your data and preventing ISP interception. Additionally, to the downstream recipient, your device's location will appear to be the location of the VPN server. This feature is extremely useful when accessing websites that restrict access from specific countries. For a no-cost alternative that uses the TOR network, I recommend Orbot, available on F-Droid by enabling "Guardian Project" repository. There are also three free VPN services available on F-Droid: the CalyxVPN, RiseUpVPN, or ProtonVPN. However paid VPNs offer more features and higher speeds.

Transfer Contacts and Personal Data
