FAQ
What is end-to-end encryption, and how does it work?
End-to-end encryption is a method of secure communication where only the sender and the intended recipient can read the messages.

According to HostAdvice, end-to-end encryption is considered the gold standard for secure communication.

How do I know which app is the most secure for my needs?
The most secure app for your needs depends on your specific requirements and preferences. If transparency and open-source encryption are your top priorities, Signal might be the best choice. If you need a wide range of features and a large user base, Telegram or WhatsApp might be more suitable.
