Full description
PostSquare — a slower kind of messaging. PostSquare is an anonymous postcard app. You write a short message, choose a design, and send it into a shared square where anyone can pick it up. Someone in another country picks up your card. Maybe they write back. Maybe they don't. There are no likes. No follower counts. No live chat. No feeds tuned to keep you scrolling. Just postcards. What's inside - The Square. A stream of postcards published by strangers around the world. Pick one that speaks to you and add it to your collection. - Your writing. Compose a postcard in a quiet, distraction-free canvas. Pick a design that fits the mood. - Reply threads. Every postcard has a time-boxed thread. Reply once, thoughtfully. When the timer runs out, the thread closes. - Stamps. Every country you send from gives you a new stamp. Build a passport of the places your words have traveled. - Your inbox. Collected postcards live in your saved shelf. Re-read them any time. Privacy by design - No advertising trackers. - No selling your data. - We ask for your location only to detect which country's stamp to give you. The coordinates are used once for that lookup and then discarded — we never store them. - Your postcards can be reported and moderated for safety, but we do not read them for advertising or profiling. Made for slow moments PostSquare isn't optimized for engagement. It's optimized for a single, considered message a day. If you already spend enough time on apps that hurry you, this one is meant to feel different. We're a small independent team. Feedback goes straight to us at [email protected].
