(I can’t believe I’m replying to a spam account) In case you can’t read my linked comment:

It’s not open source. There’s no way to actually verify any of their claims.

As others pointed out: “Contact Us” with gmail, facebook, twitter, or instagram. Any company (or individual) remotely advocating for privacy would be using (semi-)private services, even when advertising their own alternative.

The terms of service / privacy policy includes:

WireMin establishes a self-organizing network only by a number of active instances of WireMin apps. WireMin, as a protocol, utilizes advanced security and time-tested cryptography to provide a private messaging tool and social network. All of those are achieved in a democratized network without relying on a cloud service or back-end server.

No single bit of user data will be collected. WireMin is not even capable of doing that.

No user information will be provided to us, not a single bit.

however, it also contains

WireMin collects minimum device information

and

Occasionally for WireMin App on mobile devices, an additional device notification token (e.g. iOS devices) may be collected, to enable push notifications. Again, that information is collected without exposing user identity or the device’s IP which eliminates the possibility of user tracking.

It is impossible to not receive user information, and impossible to receive such notification token without knowing the device IP. User/device info gets provided to the app developers when someone downloads their app from the app store or play store. To actually use the push notification token, it requires server infrastructure. A push notification token is useless without having a centralized server to use it. Not having any servers means you can’t use the token, and having the token spread across different servers to remain decentralized would be dangerous, as the token could be used to fake notifications from the app.

Added to that, the blatant spam and advertising that’s happening in posts like these or comments under other posts related to chat applications. Your post is part quoted “update log” and part advertisement written as if it’s a review.
