TALK PRIVATELY, SHARE PUBLICLY: Share with millions of people, but likes, replies, and follower count stay hidden, and all conversations happen in direct chats. This frees you from haters, who can no longer attack you in public, and from the anxiety of social media over-exposure. It’s liberating—everyone can see, no one can touch. Additionally, messages are end-to-end encrypted, stored only on your phone, and we don’t track or collect sensitive data. In short, Presence is the safest place to be online. Read below to find out why we are so special. GOODBYE "HATERS": Share stories publicly, but likes, replies, views, and interactions stay private. Nobody can attack your content, and there’s no pressure or worry about numbers. A DIFFERENT STORY: Unless otherwise specified, your stories won't vanish after 24 hours, so you can share select contents about yourself and your life. Perfect for keeping in touch with fans, expressing views, promoting trends, or sharing personal moments on your terms. SAFE: Privacy is our priority, but we go further—we end online abuse, anxiety, and falsehoods. Presence is your space to be yourself without feeling over-exposed. With private interactions and no profile counters, you can finally stay safe and relaxed online. PRIVATE: Chats and media are end-to-end encrypted (AES-256/RSA) and stored only on your phone. Nobody can read or see them, not even us. Unlike many chat apps, no one can see your “last seen” and you control who sees your "online" status and "read receipts". This is real privacy—the rest are just slogans. WE DON’T: Unlike social media, we remove all sources of stress or harm. We don’t collect unnecessary data, track you outside Presence, or profile you for third parties. So when you see a specific story or ad, you know we are serving you, and nobody else.
