Delta Chat is like Telegram or Whatsapp but without the tracking or central control. Delta Chat does not need your phone number. Check out our approach on privacy.

Delta Chat doesn’t have their own servers but uses the most massive and diverse open messaging system ever: the existing e-mail server network.

Chat with anyone if you know their e-mail address, no need for them to install DeltaChat! All you need is a standard e-mail account.

For encryption, Delta Chat uses openPGP in an easy and user-friendly way through the existing Autocrypt standard.
