Here's a list of reasons why you should consider moving to Signal , if you haven't already:
- End-to-End Encryption (E2EE) by Default : Signal uses the Signal Protocol, which is considered the gold standard for E2EE. This means that all your messages, calls (voice and video), and file sharing are encrypted on your device before they leave and can only be decrypted by the intended recipient's device. Not even Signal can read your communications. This is a crucial differentiator from many other apps (like Telegram, which doesn't encrypt all chats by default, or WhatsApp, which collects metadata).
- Zero Data Collection (No Metadata) : Signal is designed to collect as little user data as possible. They don't store information about who you talk to, when you talk, your contacts, group memberships, or even your profile ID. This means even if subpoenaed, Signal has almost no user data to provide, in fact all they can provide is the date + time you registered with the service and the last day (not time) one of your clients pinged their servers. Other apps, including WhatsApp, collect significant metadata, which can reveal patterns about your communication even if the content is encrypted.
- Open Source and Audited : Signal's code is completely open-source, allowing security experts and the public to inspect it for vulnerabilities and ensure its integrity. This transparency fosters trust and makes it highly resistant to hidden backdoors or malicious features.
- Non-Profit Organization : Signal is run by the Signal Foundation, a non-profit organization funded by donations. This means there are no commercial interests, no ads, and no pressure to sell user data for revenue, unlike many commercially driven messaging apps.
- Phone Number Privacy (Usernames) : While Signal historically required a phone number for registration, it now offers the option to communicate via usernames, allowing you to connect with people without revealing your phone number.
- Relay Calls : For voice and video calls, you can opt to "relay" your calls through Signal's servers, which helps hide your IP address from the other party.
- Standard Messaging Features: Signal offers all the core features you'd expect from a modern messaging app, including text messaging, group chats, voice and video calls (both individual and group), file sharing, and voice messages.
- Cross-Platform Availability : Signal is available on Android, iOS, Windows, macOS, and Linux.
- User-Friendly Interface : Despite its strong focus on security, Signal maintains an intuitive experience, removing the barrier to entry for anyone who isn't technically inclined.
