Stamplo

The Four-Eyes Check

Stamplo is built on trust — and trust starts with transparency. Every message your child sends is reviewed by two sets of eyes before it's delivered: yours, and the recipient's parent.

How it works

  • Your child writes a letter, uploads a photo, or sends a pen pal request.
  • You receive a notification and can approve, edit, or reject it.
  • Once approved, the recipient's parent does the same.
  • Letters and requests are only delivered once both parents have approved them — first you, then theirs.

Why two parents?

It's simple: two caring adults are better than one. Whether protecting your child or theirs, the Four-Eyes Check ensures nothing slips through — no unkind words, no unsafe images, and no surprises.

Can children see rejections?

Only you, as the parent, see rejected letters or requests. If you reject something your child wrote, you can help them rephrase it kindly. If the other parent rejects it, your child is never notified.

Peace of mind for everyone

With the Four-Eyes Check, your child learns to communicate with care — and you stay in full control every step of the way.
