### 5/5 — Wow. What a great tool!!!!

*2024-03-24*

This is a game changer, and it’s secure. When the rest of the world is being decrypted, my private messages will remain private.

### 5/5 — Privacy

*2024-02-08*

Highly recommend easy to chat with other people.

### 5/5 — Polynom is the privacy solution

*2023-12-14*

In a time of scattered messaging platforms, “encrypted” platforms that collect your metadata, and not being able to trust really anyone, Polynom is the culmination of years of work and an evolution of different products. Don’t sign up with any of your information, just generate your own unique cryptographic identity and go. Blazing fast file sharing, calls, and everything else you could want. This should be the standard for private messaging applications.

### 1.3.37 — 2026-02-27

What’s new in 1.3.37
• Sticky Notes are now available on mobile (with improved editing and file pasting).
• Mobile now supports database encryption for improved security.
• Better media experience: swipe through full-screen images and chat media, plus improved zoom.
• File sharing upgrades: new Share/ShareTo support and improved file transfer controls (including canceling transfers).
• Many fixes & library upgrades (including major Qt upgrades) for improved stability and performance.

### 1.2 — 2024-09-22

Code Siren is pleased to announce the release of Polynom 1.2.0

In this release we have made significant optimizations, bug fixes, and three new experimental features.

### 1.1 — 2024-07-13

Code Siren is pleased to announce the release of Polynom 1.1.0. 

In this release we have made significant optimizations; bug fixes; and added a new personal notes feature to the client

With Personal Notes, you can now direct message yourself, capturing ideas, todos and other items in a quantum secure environment that only you have access to. Our next release will build on this to allow for Sticky Notes, an advanced set up for note taking and collaboration.

The Polynom client has now gone fully asynchronous. For end users, this really means one thing - SPEED. All the optimizations are under the hood, but we think you will agree that everything runs a whole lot smoother. We have upgraded to QT 6.6.3, which brings further bug fixes and optimizations to the client.

Features:
- Personal Notes: self DM #2093

Enhancements:
- QT6.6.3: upgrade and refactor as necessary #2028
- Add social_id to note_add
- Lots of additions to prepare for Sticky Notes in 1.2
- Client: make everything async #2087

### 1.0 — 2024-05-20

In this release we have implemented new post-quantum cryptographic algorithms and enabled crypto-agility in our Pro servers. We are leaving beta proud that our key features are built on a solid foundation across all the major platforms.

### 0.15.28 — 2023-12-27

In this release we completed the separation of IDs from servers - meaning you can now assign which IDs belong to which servers, further protecting your privacy. 

Our clients continue to mature, with HIPS (Hiding in Plain Sight) adjustment sliders giving users more granular control over how their client's traffic is obfuscated over the web and FCM notifications now come to our iOS client.
