# Stamplo > Stamplo is a child-safe digital pen-pal platform for children aged 7–14, where every > letter and every pen-pal connection requires approval from identity-verified parents > on both sides before anything is delivered. There is no chat, no feed, and no > algorithm; letters are encrypted at rest and take time to arrive, like real post.
