Your child’s letters and drawings are protected with the highest standards of security — because privacy isn’t optional when kids are involved.
Encryption is a way of scrambling information so that no one but the intended person can read it. Stamplo uses AES-256-GCM encryption to protect all messages and images. Content is encrypted before storage and only decrypted securely during parental approval.
No. Stamplo never sees decrypted content. We store only encrypted text and encrypted image data — even our own internal tools can’t display your child’s content. Only the sending and receiving parents can decrypt a letter during the four-eyes review step.
Children deserve the same digital dignity as adults. Your child’s words, drawings, and ideas remain private — even from us. Stamplo is built with privacy-by-design principles, including the ICO Children’s Code, so trust isn’t assumed — it’s enforced by architecture.
