The free version of ProtonMail includes 500 MB of storage and 150 messages per day.

A paid subscription includes unlimited calls and messages. The app also allows you to quickly clear your cookies and cache (which further helps minimize the ghost factor).

Phantom VPN offers free and paid apps. As with its desktop counterpart, Adblock Browser for Android allows you to block all ads and safelist the sites you like to support. AppLock enables you to keep apps you’re not using locked with a password, PIN, pattern, or fingerprint. Locking your apps provides an added security layer if your phone is lost or stolen and someone manages to get past the lock screen. You can also use it to secure images and videos in your Gallery app. AppLock uses a random keyboard and invisible pattern lock to avoid giving away your password or pattern. You can also prevent others from disabling or uninstalling the app. Applock has a free, ad-supported option, or you can pay to get rid of the ads.
