Stamplo

Stamplo is the secure, parent-approved pen-pal platform for children aged 7–14. Built in the UK and registered with the ICO, it pairs AES-256-GCM encryption at rest with our Four-Eyes Check, so every letter and image is reviewed and approved by both parents before it is delivered. Children sign in with a family code, their own avatar, and a private four-digit PIN, and in Friend Finder they share only a first name or a nickname you approve, an avatar, their country, and up to five hobbies they choose with you, real friendships without exposing personal data.

We enforce a zero-tracking policy, strict session and cookie settings, and no advertising or tracking scripts, so your family's data stays private. Stamplo's interface is designed to foster empathy, patience, and global curiosity: children learn to craft thoughtful messages, wait for replies, and explore new cultures without likes or algorithms.

Our friendly mascot Twitch guides children through onboarding and celebrates their milestones, while every real conversation happens between verified pen pals around the world. There is no real-time messaging and nothing is rushed: you preview every letter and approve all content before it reaches your child, all within a calm, ad-free environment. Bring the magic of safe, meaningful correspondence back to childhood with Stamplo.
