About

Syncbox is a private space for just two people - a couple, or two close friends. It is not a social feed built to be seen. It is a box where letters and conversations that reach only each other pile up, one by one. The quiet wait for a letter that might be there, the flutter of opening it - all of it becomes your story together. ◆ Made for · Couples who hate watching chat messages scroll away and disappear · Partners who exchange letters on anniversaries but have nowhere to keep them · Two people in a long-distance relationship who want to send their hearts more carefully · Best friends who live far apart but still want to share everyday life ◆ Weekly letter Once a week, write a letter with real care. Attach photos and a song. You can unsend it as long as it has not been read. ◆ Q&A (two-way questions) Answer questions like "When did you first fall for each other?" Both answers are revealed only once you have both written yours. A new question each time, to know each other a little deeper. ◆ Piece letter It does not have to be a long letter. Send a small piece of your heart the moment it comes to mind, and trade replies. ◆ Feed Share today's moment with one photo and a caption. Emoji reactions and comments keep the conversation going lightly. ◆ DM (real-time chat) A messenger for just the two of you: quoted replies, emoji reactions, photos, videos and voice messages, chat search and jump-to-date. Star the messages you want to keep. ◆ Bookmarks Gather the letter lines, photos and chat moments you want to treasure in one place - your shared keepsake box. ◆ Privacy you can count on · Strictly 1:1 - connected only to the one person you invite · App lock with a PIN and Face ID / Touch ID · Notification emails never include the message body · All data travels over encrypted connections only Time passes, but what you shared can stay. Start keeping your story in Syncbox today.
