A little more private.

Your people.
Your words.
Your space.

Good conversations deserve a place of their own. Stay close with encrypted chats and files that travel straight between your devices.

Windows & web. Your conversations, protected.

PRIVATE BY DESIGN

Some things are
better kept between us.

3iphera keeps the familiar parts of messaging, and puts more thought into what happens behind them.

01 / YOUR CONVERSATIONS

A real connection.
A private conversation.

Catch up with one person or bring your group together. Text messages use end-to-end encryption, with readable history on the devices that hold your keys.

Encrypted text history. Explicitly verified devices.

02 / YOUR FILES

No upload.
Just a handoff.

Photos, videos, GIFs and documents travel through an encrypted device-to-device connection. The file and media bytes are never stored on our servers.

All file types. Direct transfers up to 256 MiB.

01

Choose what to share.Pick a file and offer it to your verified contact’s device.

02

Keep both apps open.Both devices need to be online, and the recipient accepts the transfer.

03

Save it on your device.The recipient saves a local copy before closing 3iphera.

A LITTLE MORE CONTROL

Privacy you
can participate in.

Your devices are part of your privacy. 3iphera makes the important choices visible.

01

Know the device on the other end.

Compare the full SHA-512 device fingerprint through a trusted channel. New devices need fresh verification before you share.

02

Keep your message keys safe.

Export a passphrase-protected key backup before signing out. It helps you recover encrypted text history on a new installation.

03

Understand where your content lives.

Text history can be synced as end-to-end encrypted data. Files are a live handoff, with no server file copy to retrieve later.

A FEW THINGS TO KNOW

Before you
say hello.

Are my files stored on 3iphera’s servers?+

No. File and media bytes move through an encrypted connection between devices. A relay may forward encrypted traffic when needed, but it does not keep a file copy.

Why do both devices need to be online?+

There is no server file copy to download later. Keep 3iphera open on both devices until the transfer finishes, then save the received file locally.

What about text message history?+

Text history can remain on the messaging server as end-to-end encrypted data. Your devices use their encryption keys to read it. Back up those keys before signing out if you want to recover earlier history.

Can I use 3iphera on macOS?+

macOS is planned after Windows testing and production acceptance. The web app is available through the browser link; a macOS desktop installer is not available yet.
