What is Signal app?

Signal is a secure messenger app where you can speak freely without worrying being spied on. It uses an end-to-end encryption to protect your messages so that no one can read them.

Giving the best security for the users’ privacy is the top priority of Signal. They ensure that no one can read your messages or listen to your calls.

So, if you ask, “Is the Signal app safe?” We confidently say, YES!

Every message, photo, video, document, and even your call are encrypted. It’s only you and your interlocutors who can read them. Signal app takes your privacy to a serious level.

Even Elon Musk and Edward Snowden recommended Signal for its safety.


Signal works independently. It doesn’t cooperate with any companies. Unlike WhatsApp, which’s owned by Facebook. I believe you have heard about how they shared your data for advertisement targeting purposes.

The best thing is that Signal is free for everyone. No additional purchasing is needed to use the services.

How Signal app makes money, then?

They receive donation from everyone. This is a way to stay independent in order to provide protection for your privacy.

They open donation from $3, $5, $10, $20, $50, $100 or custom amount. Every penny of your donation is matters. It helps them to pay for the development and support. And to keep your privacy private.

Is Signal better than WhatsApp and Telegram?

We’ll try to compare several things, such as:

  • end-to-end encryption
  • data backup
  • advertising policy
  • user data
  • file size limit
  • number of group member

Scroll down to read the explanation.

1. End-to-end encryption

Both Signal and WhatsApp use an end-to-end encryption by default. It means that all messages and files are encrypted between devices.

In the Telegram, the end-to-end encryption only applies to the secret chat. The normal chat doesn’t have this feature.

If you want to keep using Telegram, then we suggest you to use the secret chat rather than the normal chat.

Signal, Telegram, and WhatsApp have similar basic feature to send messages. You can send texts, images, audio, documents, videos, contacts, and also location. The three apps also allows you to have audio and video calls, either individual or group call.

Those three apps have a self-destruct feature. The messages will disappear automatically after a period of time. No one can recover the messages once they are deleted.

2. Data backup

Signal only stores the data in your smartphone, tablet, or computer. No third-party app is affiliated to backup your data. No cloud service to store nor backup your device. So, once you lose or break your device, your data are gone.

WhatsApp mainly stores the data in your smartphone, tablet, or computer. While for backing up the data, it uses a third-party service like Google Drive or iCloud. However, the data are not encrypted at all which enable others to see it.

Telegram also uses the device to store the data. While for backing up, it has its own cloud service to use. The good thing is that the stored data is encrypted.

3. Advertising policy

Signal has no ads and probably will never put ads on its app.

Telegram also has no intention put any ads on the app.

WhatsApp shares any information with Facebook for advertisement purposes.

4. User Data

Signal doesn’t take any data linked to you. It collects the phone numbers in your contacts, but they are only used for app function purposes.

Telegram collects some data linked to you, such as user name and ID, phone numbers, and contacts.

WhatsApp collects many data linked to you, such as device ID, advertising data, purchase history, coarse location, phone number, user ID, product interaction, crash data, performance data, other diagnostic data, payment info, and contacts.

5. File size limit

However, there is a slight different in the size limit of a file that you can send.

Use Signal and Telegram if you want to send big files up to 1.5GB. While WhatsApp can only send file less than 100MB.

6. Group member

Telegram can have up to 200,000 people in one group. If you are having a community with a large number of members, Telegram can be your best choice. You can easily share or broadcast information to everyone.

Signal limits the group members to 150 people.

While WhatsApp is only 256 people.
