🔑 Invite Codes and Friend Finder
Children can connect using 8-character codes shared in real life, or through our parent-controlled Friend Finder — where only public profiles approved by you are shown.
👀 Four-Eyes Check
Parents on both sides must approve all pen pal requests, letters, and images before anything is delivered — so you're always in control of what's shared.
🔒 Encryption
All messages and photos are end-to-end encrypted at rest and in transit—built on proven security standards.
🏅 Collect Stamps
Kids earn country-themed and limited-edition stamps with every exchange—spark their curiosity about the world!
🧑🎨 Avatars & Badges
Choose your own avatar and unlock stamps as you find more pen-pals.
📚 Learn & Connect
Practice writing, learn about new cultures, and make real friendships—safely guided by parents.
