Telegram, a messaging app released in 2013, has grown significantly in popularity, boasting over 700 million active monthly users as of 2023. This rise in popularity spotlights vital questions: Is Telegram safe? Is Telegram encrypted? How does Telegram work? These queries center around the app's privacy and security features.

Telegram's Security Features

✅ Encryption: Telegram encrypts messages, but it's crucial to note that end-to-end encryption is only applied to secret chats. In regular private and group chats, messages are stored on Telegram's servers, accessible to the service.

✅ MTProto Protocol: Telegram, renowned for prioritizing user privacy and security, has developed the MTProto protocol specifically for its platform. The MTProto protocol plays a crucial role in securing user data, encrypting messages in a way that ensures they are only readable by the intended recipients. With MTProto, Telegram underscores its dedication to user privacy by effectively safeguarding communications from unauthorized access.

✅ Secret Chats: These chats offer full end-to-end encryption and are not stored on Telegram’s servers. They also feature self-destructing messages, enhancing privacy.

✅ Additional Security Measures:

Encrypted voice and video calls
Encrypted cloud storage
Two-step verification
Passcodes
Advanced privacy settings

🔐 Using Telegram Safely

To add an extra layer of protection and privacy, you should:

Enable Two-Step Verification: Adds an extra layer of security by requiring a password in addition to the SMS code.

Regularly Clear History: Routinely clearing chat history and disabling active sessions on unused devices can prevent data breaches.

Adjust Privacy Settings: Limit who can see your phone number and set up local passcodes to protect against unauthorized access.

Use Secret Chats: For sensitive conversations, leverage the end-to-end encryption and self-destruct timer of secret chats.

Note: create messages that automatically delete after a set time once the recipient opens them. To do this:

Initiate a secret chat with the desired contact.
In the chat window, tap the three dots icon located in the upper right corner.
Choose the "Auto-Delete" feature.
Specify the duration after which the message should vanish post-opening.

Send self-destructing media: Use self-destructing media in Telegram to ensure messages disappear after a set time, enhancing privacy in both regular and secret chats.

Delete messages for ultimate privacy: Delete messages in regular and group chats for added security, especially if a device is lost, to prevent unauthorized access to your private conversations.

🔍Customizing Visibility in Telegram

Telegram offers various privacy settings that allow users to control who can see their personal information, such as their phone number, profile picture, and so on. These settings are particularly useful for maintaining privacy and separating personal and professional life. Here's how you can manage these settings:

Hiding Your Phone Number:

To hide your phone number, go to Settings > Privacy and Security > Phone Number in the Telegram app. > You will find an option labeled "Who Can See My Phone Number." Here, you can select "Nobody" to hide your number from everyone.

This setting is essential as Telegram uses your phone number for account authentication, but you might not want it visible to all users.
Additionally, you have the option to customize the visibility of your phone number. It can be made visible to no one, only your contacts, or everyone, giving you control over who can access this information.

Hiding Your Profile Picture:

To hide your profile picture, open the Telegram app and navigate to Settings > Privacy and Security. > Select the "Profile Photos" option.

This will bring up a series of options regarding who can see your profile picture. You can choose to make it visible to all users, only your contacts, or hide it completely.
If you want to set exceptions (for instance, if there are specific users you want to restrict from viewing your profile picture), you can do so at the bottom of the same page.

These privacy settings in Telegram help you maintain control over your personal information, contributing to a safer and more private messaging experience. By adjusting these settings, you can ensure that sensitive information like your phone number and profile picture are shared only with those you trust or choose to share with.

🔓 Safety and Privacy Risks

Vulnerabilities for Illegal Activities: Telegram's encryption and privacy features have unfortunately made it a platform for illegal activities, including phishing, financial and crypto fraud, hacking, drug trafficking, and extremism.

Regular Chats Not Fully Encrypted: Regular chats in Telegram lack end-to-end encryption, potentially exposing messages to security risks.

Cybercrime Exploitation: Telegram's rising popularity and security features have made it a target for hackers and cybercriminals, exploiting its platform for various malicious activities.

Note! Be Cautious of Scams and Phishing — remain vigilant against unknown users and avoid clicking on suspicious links.

Data Collection: Signal, Telegram, WhatsApp, and Facebook

Signal is the most private, collecting only your phone number for account creation and no other identifiable data. Telegram gathers slightly more, including contact details and a user ID, but this is relatively minimal compared to other messaging services. In contrast, WhatsApp and Facebook accumulate a broader array of personal information, making them more intrusive in terms of data collection.

👀 Business and Privacy on Telegram

1) Is conducting business on Telegram safe?

Yes, conducting business on Telegram is generally safe. The platform encrypts messages, providing a secure environment for business communications. However, it's crucial to use its "Secret Chat" feature for end-to-end encryption to ensure the highest level of security.

2) Can personal data be accessed through business accounts on Telegram?

The risk is minimal, especially when using secret chats for data protection.

Telegram – Ideal Choice for Business & Personal Use

Telegram's suitability for business, earning potential, and its compatibility with personal life and space in messaging platforms can be understood through various aspects of its functionality and security features:

✅ Enhanced Security: Telegram is safer than many messaging apps, offering encrypted messaging with fully secure secret chats not stored on servers, ideal for confidential business communication.
