Take the Safety Check →🔑 Invite Codes & Friend Finder
Children connect only if you allow it. Parents can share an 8-character Family Code with other families, or enable the Friend Finder so their child can appear in the parent-controlled search.
👀 Four-Eyes Check
Every pen pal request, letter, and image must be approved by a parent on both sides before it is delivered — so nothing is shared without your consent.
🔒 Encryption
All letters and images are encrypted at rest and in transit — protecting children's privacy from end to end.
🏅 Collect Stamps
Kids earn country-themed and limited-edition stamps with each safe exchange — sparking curiosity about the world and rewarding positive connections.
🧑🎨 Avatars & Badges
Children choose their avatar and unlock badges as they connect with new pen pals — celebrating creativity and safe exploration.

Practice writing, learn about new cultures, and build real friendships — all within a parent-approved, child-safe environment.
