We are a private messaging, cybersecurity, and

social media company that not only focuses on protecting privacy on personal devices, but also protects user information after it is shared

We believe that one’s right to privacy should not end the moment they click “send”, and that we all deserve

the same right to privacy online that we enjoy in our own living rooms.

Our flagship product, DatChat Messenger & Private Social Network,

is a privacy platform and mobile application that gives users the ability to communicate with the privacy and protection they deserve.

Recently, we have expanded our business and product offerings to include the development of our Myseum platform, a secure digital content

management and storage solution for families, groups and individuals.

In addition, as a result of our acquisition of RPM Interactive,

in October 2024, we have repositioned our majority-owned subsidiary, Dragon Interact, Inc.

(recently renamed RPM Interactive, Inc.)

away from the development of the Habytat platform to focus on becoming an AI generated publishing company of trivia mobile game apps and

vodcasts/podcasts designed to publish content across hundreds of evergreen topics every day and be distributed to all major streaming

See “Business – RPM Interactive, Inc.” and “Business – The Habytat.”

We are a privacy and social media technology company

focused on innovative and creative user platforms.

Our flagship platform is “Picture Party by Myseum”, a next-generation on

demand social networking platform that makes it easier and private to share your photos, videos and messages both today, and for generations

Our innovative social media platform brings a fresh and needed approach to digital media and content management, allowing users

to create a digital legacy that makes it easier to share both today, and with future generations.

The platform is backed by both patented

technology and proprietary software.

We also operate the DatChat Messenger & Private

Social Network, which presents technology that allows users to change how long their messages can be viewed before or after users send

them, prevents screenshots, and hides encrypted photos in plain sight on camera rolls.

The patented technology offers users a traditional

texting experience while providing control and security for their messages.

With the DatChat Messenger, a user can decide how long their

messages last on a recipient’s device while feeling secure that at any time, and delete individual messages or entire message threads,

making it like the conversation never happened.

Myseum Social Media

We recently launched our Myseum social media platform,

an innovative social media platform that brings a fresh approach to digital media and content management,

allowing users to create a digital legacy that can be easily shared today and with future generations.

Backed by AI technology and proprietary

software, the multi-tiered social media ecosystem enables individuals, families, and other groups to store and share digital content such

as messages, photos, videos, and documents within a highly secure and private family library.

Myseum allows users to create amazing

albums and galleries for everyone to see, create special private and secure galleries with limited access, personalize a user’s

newsfeed with updates from other Myseums and leave time released video messages for both now and future generations.

Picture Party Platform

In December 2025, we launched Picture Party

by Myseum , a new on demand social networking and social sharing platform designed to address growing concerns around content control,

security, and intentional digital connection.

The platform was developed to capitalize on the widespread need for a more controlled and

purposeful way to share photos and videos-one that solves persistent privacy and ownership challenges not adequately addressed by existing

social media offerings.

Picture Party by Myseum introduces a new way to make sharing photos, videos and messages easier, a lot more fun

Picture Party is much more than a shared album;

it’s a complete personal and private social network with a live feed that

updates instantly as all guests’ posts.

A user can share a post with dozens of pictures, comment and react.

It even organizes the photos

in an album, or the user can relive the Picture Party with all the comments and posts as they happened.

Unlike group chats that are unorganized,

no matter when a user joins the Picture Party, they can see everything from the beginning.

Picture Party makes it easier and more fun

to share with the people right next to the user, or anywhere in the world.

Picture Party solves everyday sharing frustrations

by eliminating the common headaches of modern photo sharing:

● No more passing around a phone for others to

view photos and videos.

● No more crowds gathering over a user’s

shoulder to see a clip.

● No more debating whether to text, drop, email,

or tag group photos.

● No more struggling with social media privacy,

data exposure, or AI training risks.
