Let’s have a quick look at how these three are different from each other.
| Parameter | Telegram | Signal | |
|---|---|---|---|
| User Interface | The UI is simple, with self-explanatory tabs like call, chats, status, search and three dots heading into the settings section. | There are no different tabs, but everything is displayed on a single screen. The only thing that remains the same as compared to WhatsApp is the icon at the bottom to start a new or a secret chat. | The User interface is quite similar to WhatsApp, but like a telegram, most of the icons are placed on a single screen only. |

The Final Verdict
Now that we know all the prominent features and the data collected by these apps, let’s conclude which out of these three messaging apps are safest to use.
There are no qualms in saying that Whatsapp may have ruled this business for several years but it is surely not the safest app to use. Unlike Signal, both WhatsApp and telegram do not have an end to end encryption in case you take back-up of your chats, files and documents. Telegram only have encryption if you use the secret-chat feature. If you are looking for something secure then there is no better substitute than a Signal. It has all the safety features as it uses the default four-digit password to encrypt all your messages.
The signal may not offer as many features as the other two are offering, but one thing can be assured of that no amount of data or information will ever be leaked from this platform.
No one would have ever gone into such depth if WhatsApp wouldn’t have come up with its new privacy policy. But now all this information has raised many eyebrows and has compelled people to switch to a better and secure substitute.
