Write messages now. Share them in the future. Sealed Letter is a private and thoughtful way to write messages, letters, instructions, or important information today, then choose when and how they can be accessed later. It is designed for words that deserve care, privacy, and the right timing. Instead of sending a message immediately, you can prepare it in advance, keep it sealed, and decide who should receive it, when it should become available, and how it can be opened. Whether youβre writing something heartfelt, practical, or important, Sealed Letter helps you stay in control until the moment is right. What you can do with Sealed Letter Write future messages: Create meaningful letters, personal notes, guidance, or important instructions that can be delivered or accessed at a later time. Seal letters until theyβre ready: Keep your message private until the access conditions you choose are met. Choose how letters are shared: Let a letter be picked up securely with letter details and a password, or deliver it directly via email or inside the app to a chosen recipient. Schedule access for later: Letters are not available immediately unless you choose them to be. You decide when a letter can become available in the future. Assign trusted people: Choose trusted contacts who can receive letters or help release them when needed. You decide their role and level of access. Stay in control: Your letters remain private and controlled by you. Nothing is shared unless you explicitly choose how and when it should be shared. Intentional by design: Sealed Letter is not a chat app or social network. There are no feeds, public profiles, comments, or replies. It is a quiet space for messages that deserve time and care. Simple and calm experience: Clear language, minimal distractions, and a gentle interface help you focus on what matters most. Sealed Letter gives you a peaceful way to prepare meaningful messages for the future, so the right words can reach the right person at the right time.
