Privacy is on the wane in this digital age. Most messaging apps ask for your phone number, track your conversations, and show you targeted ads. Delta Chat is different. It's a smart messaging app that will revolutionize communication.
Delta Chat is a free, open-source, and privacy-focused messaging app that works over email, without compromising on speed or convenience.
You can text without giving out your phone number and chat securely without signing up for another account.
What makes Delta Chat special?
Unlike WhatsApp, Signal, or Telegram, Delta Chat doesn't rely on a centralized server or phone number. Instead, it uses your existing email account to send and receive messages. This means:
- No phone number needed - sign up with any email.
- No new account needed - works with Gmail, ProtonMail, Tutanota, etc.
- No corporate tracking - your data stays private.
How does it work?
Delta Chat sends messages as encrypted emails in the background, but the experience feels like a real-time chat app. You get:
- Instant messaging speed (no manual email refreshing).
- End-to-end encryption (if both users enable it).
- No reliance on a single company's servers (you control your data).
Why Delta Chat is different
No phone number? No problem.
- Most messaging apps force you to give out your phone number. Not Delta Chat.
- Anonymous sign-up: just use an email - no personal details needed.
- No SIM? No worries. Perfect for travelers, privacy-conscious users, or people without a phone number.
Email-powered, but not "email slow"
Delta Chat uses email to send messages, but it feels like messaging is instant.
