End-to-end encrypted chat and file transfer for complete privacy and security.

Underpass is different from every other encrypted chat app because it does not use a third-party service. It's just two devices and a password. Peer-to-peer. There's no signup. No account. No phone number, email, contacts, or any personal information requested, not even your real name.

You can chat securely over the internet or on a LAN, such as in an office, school, coffee shop, or home. All of your data is encrypted before it's sent over the network, and it can't be decrypted except by the other device using Underpass. Industry-standard AES-128 encryption algorithm.

Chat Features:
* File transfers of any file type
* Inline images, including animated gifs
* Unicode text and emoji

Underpass for iOS is also available, sold separately in the iOS App Store. You can chat with a Mac, iPhone, iPad, or iPod touch using Underpass.

Release Notes

11/04/2017 | Version : 1.0.1 | Size : 2.5 MB
The help book has been updated to discuss Underpass for iOS.

Minor improvements:
- When there are multiple LAN chats listening for partners, each chat now always preserves its Bonjour name.
- Text fields in Settings now use character wrapping rather than word wrapping. This makes IPv6 addresses look better.
- If a text field in Settings is editing when a chat starts, the new value is now always kept.
