The meaningful comparison isn't just about encryption – it's about what data exists at all and what identity is required.
WhatsApp offers E2EE for messages but requires a phone number, collects metadata, and is owned by Meta. Signal is E2EE with strong privacy defaults, but still requires a phone number. Telegram's default chats are not E2EE – only "Secret Chats" are.
EXTRA SAFE differences:
1.
No phone number or email required – your identity is a cryptographic key pair, not a personal identifier.
2.
No metadata collected for profiling – we don't build a picture of who you talk to, when, and how often.
3.
Ephemeral by default – conversations don't accumulate.
4.
Self-custodial crypto wallet built in – ownership extends to your money, not just your messages.
Security isn't just about the encryption protocol. It's about what data exists in the first place. The safest data is data that was never collected.
