The Best Privacy and Security Apps for Android

A smartphone in the 21st century is an integral part for many people who simply cannot imagine their life without this device. This is not surprising since smartphones currently have enormous capabilities and a large number of functions.

The flip side of the coin is that cybercriminals (and governments) have evolved as well and can hack into a phone, steal personal data and money, read text messages, and even eavesdrop on calls. In the news headlines, there are often reports of security breaches of smartphone owners, which means that you need to take care of the security of your data.

Below you will find a list of Android applications that will be useful to ensure the safety of your stay on the Internet and the protection of personal data. We strongly recommend that you download the applications you need only from an official source, and best if it is the Google Play Store.

Voice Calls and Messaging

Applications that use end-to-end encryption provide the highest level of confidentiality since sent messages are available only to the sender and recipient. Here are some instant messengers that offer the maximum level of protection for your correspondence and data transfer.


Telegram is probably the most secure free instant messengers for smartphones and PCs that allows you to exchange not only text messages, but also various media files. To protect against surveillance, Telegram uses its own protocol development – the cryptographic protocol MTProto. If you want to completely protect yourself, you can use the Secret Chat function. Installation, registration, use, like all other Telegram functions, are free.

Signal Private Messenger

Signal Private Messenger gives users the ability to exchange messages, files, and make calls. Its distinguishing feature is open source code and unprecedented message confidentiality through an advanced encryption protocol. It does not store data that could be transferred to someone, and even developers cannot get access to the correspondence of users.

Wickr Me

Wickr Me Secure Messenger is a secure instant messenger. With it, you can send various kinds of messages that are encrypted using AES 256, ECDH 521, and RSA 4096 TLS.

You will be able to determine who will be able to read your messages and amount of time to read.


ProtonMail is an open-source secure webmail service that can be a good choice for those who have reason to fear the surveillance and interception of their mail. It quickly encrypts messages between users and allows you to send encrypted messages to users of other systems. ProtonMail allows you to specify the lifetime of the message, after which the message will be automatically deleted. Its servers are located in Switzerland where personal data is protected by law.
