Stamplo

End-to-End Encryption

Your child's letters are protected with the highest standards of security — because privacy isn't optional when kids are involved.

What is encryption?

Encryption is a way of scrambling information so that no one but the intended person can read it. Stamplo uses strong encryption at rest to protect all letters and images. Messages are locked as soon as they are sent and only decrypted for parental review.

Can Stamplo read the letters?

No. Stamplo never reads or stores decrypted content. Letters are encrypted before storage, decrypted only during parent approval, then re-encrypted until safely delivered.

Why it matters

We believe children deserve the same digital dignity as adults. Your child's words, drawings, and ideas are private — even from us. Stamplo is built so trust doesn't have to be assumed — it's enforced by architecture.
