<div id="readability-page-1"><article>Next-generation private social networking platform redefines how users share photos, videos, and protect their privacy NEW BRUNSWICK, N.J., Jan. 13, 2026 (GLOBE NEWSWIRE) -- Myseum, Inc. (Nasdaq: MYSE) (&#34;Myseum&#34; or the &#34;Company&#34;), a privacy-first social media and technology innovator, today announced the official iOS and Android release of Picture Party by Myseum across North America. Myseum had recently debuted its new instant social networking and social sharing platform with the iOS beta launch in December 2025. Picture Party by Myseum addresses the unmet need for a more controlled and purposeful way to share photos and videos, solving persistent privacy and ownership challenges not adequately addressed by existing social media offerings. Users can instantly create private, encrypted spaces, called “picture parties,” to share photos and videos in curated, personal feeds. “The official launch off Picture Party by Myseum in North America is the beginning of a worldwide rollout over the next several months. Additionally, these next few months will see the addition of many new features and revenue generating channels as our user base grows,” said Darin Myman, Chief Executive Officer of Myseum. “This launch advances our strategy to scale a purpose-built social sharing experience that prioritizes privacy, ownership, and meaningful connection—capabilities in high demand among today’s social media users. In a world where AI is growing at an exponential pace, Picture Party creates a safe and private space to protect our personal content and information.” In addition to Android, Picture Party by Myseum is currently available for download in the iOS app store and Google Play store. A use case video is available on YouTube. Additionally, another fun promotional video is available on YouTube. About Picture Party by Myseum Picture Party by Myseum introduces a new way to make sharing photos and videos easier, a lot more fun, and private. 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 your guests’ posts. You can share a post with dozens of pictures, comment and react. It even organizes your photos in an album, or you can relive the Picture Party with all the comments and posts as they happened. Unlike group chats that are unorganized, no matter when you join the Picture Party, you can see everything from the beginning. Picture Party makes it easier and more fun to share with the people right next to you, or anywhere in the world. Picture Party solves everyday sharing frustrations by eliminating the common headaches of modern photo sharing: <ul type="disc"><li>No more passing around your phone for others to view your photos and videos.</li><li>No more crowds gathering over your shoulder to see a clip.</li><li>No more debating whether to text, drop, email, or tag group photos.</li><li>No more struggling with social media privacy, data exposure, or AI training risks.</li></ul> Whether you’re at a family gathering, wedding, sporting event, vacation, concert, school function, or business meeting, everyone becomes a photographer, and no moment is missed. Instantly share group shots without ever chasing people for their copies again. How it works: Picture Party lets users instantly create private, encrypted spaces — called Picture Parties — to share photos and videos in curated, personal feeds. Users can: <ul type="disc"><li>Create unlimited Picture Parties.</li><li>Invite anyone via text, QR code, or in-app invite.</li><li>Launch a Picture Party (a timed or ongoing shared event) in under a minute.</li><li>Add titles, comments, and reactions to posts.</li><li>Maintain complete control over privacy, interaction settings, and who can view or contribute.</li></ul> Privacy: The only people that can see your pictures are the ones who you invited to the picture party. All your media and texts are private and encrypted. You decide if pictures can be saved by your guests or who can invite people to the party. “Picture Party by Myseum was built to address a clear gap in today’s social media landscape—where users are increasingly concerned about privacy, content control, and how their personal moments are shared,” said Darin Myman, Chief Executive Officer of Myseum. “By combining time-bound events, user-specific media permissions, and a simple, intuitive experience, we are redefining how users engage around shared moments.” Importantly, the technology underpinning Picture Party by Myseum is supported by a newly allowed U.S. patent. The patent covers the core personal and private social networking architecture behind Picture Party by Myseum and represents a significant milestone in Myseum’s intellectual property strategy. The Company believes the new IP is foundational to a new category of private social interaction and a key driver of long-term platform value. About Myseum, Inc. Myseum, Inc.
