1. Signal

Supported devicesAndroid, iOS, macOS, Linux, Windows
Rating in App Store4.5/5
Rating in Google Play Store4.8/5

Signal’s surged to the top of the app store rankings lately, thanks to WhatsApp’s privacy policy update stipulating that user data is shared with its parent company, Facebook.

So if you’ve ever needed a reason to switch to a more secure messaging app, this is probably it.

Signal uses its own protocol for end-to-end encryption across voice calls, video calls, and instant messages. The technology is open source, meaning the code can be audited by cybersecurity professionals. What’s more, Signal uses a unique device safety number to ensure that your messages and calls are actually reaching their intended recipient.

Users also have the option to secure the app with a PIN code and send self-destructing messages.

2. DuckDuckGo

TypeInternet search engine
Supported devicesChrome extension, Android, and iOS
Rating in App Store4.9/5
Rating in Google Play Store4.7/5

Google is worth hundreds of billions of dollars mostly because it holds a vast trove of data. It tracks your every move: what sites you click on, what things you buy online, and where you log on to the internet from.

DuckDuckGo is a privacy-focused alternative. It doesn’t store any user data, IP addresses, or personal information. And there’s no advertising. Moreover, it forces websites to use an encrypted connection.

You can download the DuckDuckGo browser (as an alternative to Chrome) or navigate to duckduckgo.com for search queries.

3. ExpressVPN

TypeVirtual private network
Supported devicesAndroid, iOS, macOS, Linux, Windows, browser extensions
Rating in App Store4.7/5
Rating in Google Play Store4.2/5

A Virtual Private Network (VPN) should be your go-to app to encrypt all internet traffic flowing to and from your device. It’s necessary when you consider that you might connect to poorly secured Wi-Fi networks or fork over financial information through unsecured sites.

VPNs are an excellent method to cover your digital footprint and port your location to different parts of the world for streaming sports and unblocking streaming media sites.

Price5.99 USD a week
Supported devicesAndroid
Rating in Google Play Store3.5/5

If you’re self-employed or freelancing, you need to build out your network. However, handing out your personal cell phone number can leave you inundated by follow-up calls.

2ndLine gives you an alternate phone number for business calls or when you want to keep your personal number private.

5. ProtonMail

PriceFree with up to 1GB total storage, 150 messages a day, and access to Proton Calendar Drive, and VPN.
Supported devicesAndroid, iOS, browser extensions
Rating in App Store4/5
Rating in Google Play Store4.3/5

Google’s data mining doesn’t just extend to search. Gmail also has algorithms at work, establishing a metadata profile to serve you more targeted advertisements.

If you aren’t a fan of metadata profiles, then it’s worthwhile to shift to ProtonMail, a far more secure alternative to Gmail.

Like Gmail, ProtonMail is free to use. But that’s where the similarities end. You don’t need any personal information to sign up. All email is end-to-end encrypted, which means the company can’t decipher the content of your messages.

ProtonMail is incorporated in Switzerland and therefore has to operate within the confines of the country’s rigid privacy laws.

Founded in 2013 by scientists at CERN, ProtonMail offers password-protected emails and a self-destruct option. It’s also open source, so anyone can audit the code if they wish.

6. LastPass

TypePassword manager
PriceFree with premium plans available
Supported devicesAndroid, iOS, Windows, MacOS, browser extensions
Rating in App Store4.5/5
Rating in Google Play Store3.8/5

We tend to use the same password or similar ones, across all the apps and sites we access⁠—it’s just easier. But this habit puts you just one hack away from identity theft.

With password manager LastPass you can use long, random passwords that are all different while keeping them safely squirreled away in one place. You can also use it to save other data points such as driver’s license information, social security numbers, credit cards, and bank account details.

It also doubles up as a password generator, meaning you don’t have to come up with new ones on your own frequently.

7. Bouncer

Price2.98 USD
Supported devicesAndroid
Rating in Google Play Store4.3/5

We’re so used to automatically granting all app permissions that we tend to forget how comprehensive some of these can be.

Bouncer helps mitigate this potential privacy oversight: The app can toggle permissions on your behalf, preventing apps from accessing more data than they need.

Let’s say you want to tweet a picture of your beach vacation, but you’ve disabled camera settings on the Twitter app. Bouncer will help you access it and automatically turn it off after a predetermined time.

And you can use it on a wide range of apps.

Supported devicesAndroid, iOS, Windows, macOS, Linux
Rating in App Store4.7/5
Rating in Google Play Store4.6/5

When LastPass announced that it was going to be limiting the number of devices users were allowed to sync their passwords on with a free account, Bitwarden became the de facto free password manager. Unlike LastPass, Bitwarden lets users sync passwords across unlimited devices for free. There’s also a premium option if users want more features like 1 GB of encrypted file attachments and secure login via Yubikey, U2F, and Duo.

Tips for protecting your privacy on apps

While downloading privacy-friendly apps is a great idea, there are ways to protect your privacy while using other apps: 

Before You Install an App

  • Always download apps from the official app stores. Official app stores like the Google Play Store and Apple’s App Store have stringent requirements that protect users from potentially malicious apps.
  • Find out what sort of information the app will be able to access. Before downloading an app, read the reviews and see if you can spot anything suspicious about the app.
  • Check out the permissions. Ensure that the permissions requested by the app make sense and check if it might share information with external parties.

Your Privacy on Apps You Already Have

  • Review the app’s permissions. With each new update, have a look at the app’s permissions and see if it makes sense for the app to require access to certain features on your device.
  • Limit location permissions. Where possible, try to limit the sort of information apps can collect from you, this includes location data, photos, and calendar information.
  • Don’t automatically sign up for apps with a social network account. This helps to limit the sort of information that an app can collect about you.
  • Always keep apps updated. Outdated apps could possess security flaws that give hackers loopholes to install and distribute malicious software.
  • Delete apps you don’t need. Create space on your phone by removing certain apps you no longer use.
