Relation Link vs Check In

Relation Link is a small, slow place for two people. You write one message. You seal it. It lands at your partner's hour, not yours. That is the whole app. One letter a day, between two devices. No groups, no broadcast, no algorithm deciding what gets seen. The thread is shared by two phones and lives nowhere else - there is no cloud archive of your conversation, no profile, no follower count, nothing to scroll past. The ritual is gentle. Open the app in the evening, or the morning, or whenever the day quiets down. Write what you would have said if they were in the room. Press send, and the envelope is sealed. While it travels, you cannot edit it, retract it, or check whether they are typing back. When their phone reaches the right hour, the lantern is lit on their side and the letter opens. They write theirs the same way. One a day, each. Privacy is the floor, not a feature. Every message is end-to-end encrypted with NaCl before it leaves your device. The keys live on the two phones in the pair. We - and any server in between - see only sealed bytes. There are no read receipts shipped to a backend, no analytics tied to the contents of your thread, no recovery from our side if you both wipe the app. Two devices, one quiet line. Pro is one purchase, paid once. It unlocks every theme and every effect - Paper, Midnight, Linen, Lantern, Tide, Garden, Dust, Iron, Vellum, Hearth - so the envelope can match the room your message arrives in. There is no subscription, no ad-supported tier, no "premium plus." When you buy "For me & them," your partner gets Pro automatically; their copy of the app simply unfolds, no code to forward, no setup to do. Made for two. Quiet on purpose.
