Frequently Asked Questions

If you're a parent, legal guardian, teacher, or simply curious — you're in the right place.

Who is Stamplo for?

Stamplo is built for children aged 7–14 who want to connect with pen pals in a slow, safe, and intentional way. Parents or legal guardians oversee every interaction.

Is it really safe?

Stamplo is designed to be one of the safest digital spaces for kids. All letters and pen pal requests must be approved by both sets of parents or legal guardians. Messages are encrypted at rest, and children are never visible to other families without parental controls and approval.

Can children send physical letters or postcards to their pen pals?

Some families choose to exchange physical letters or postcards once they feel comfortable with their pen pal connection. If parents decide to share a mailing address, that decision is entirely up to them.

Stamplo itself is designed for digital pen pal letters with full parental approval. Any exchange of contact details or communication outside the platform takes place independently and should always be decided by the parents involved.

Why do parents have to verify their identity?

To keep Stamplo safe, all parent or legal guardian accounts must complete a one-time age and identity verification before children can use the platform. This helps ensure that only genuine adults create family accounts.

Verification is handled by our independent partner (currently Didit). Stamplo only receives a confirmation that the adult is verified — we never store ID documents or images.

Do you track children or show advertising?

No. Stamplo does not track children, show advertising, or use behavioural analytics. We collect only the information needed to run the service — such as a child’s first name, country, and the letters they send.

All messages are encrypted and reviewed by parents before delivery. You can read more in our Privacy Policy.

Do children talk in real time like a chat app?

No. Stamplo works more like traditional pen pals than instant messaging. Letters take time because both parents must approve them before delivery. This slower design encourages thoughtful writing and removes the pressure of real-time chat.

Can my child talk to anyone they want?

No. Stamplo uses a private invite-code system or parent-approved public profiles. Nothing is automatic — your child can only connect after you approve their request, and the other parent does the same.

How do letters work?

Children can write letters to pen pals once both parents have approved the connection. When a child sends a letter, you (the parent or legal guardian) must approve it. Then the recipient’s parent or legal guardian does the same. Only then is it delivered.

Can letters include images?

Only if both sets of parents or legal guardians allow it. You can toggle this setting in your dashboard. Every image is reviewed as part of the Four-Eyes Check before it's delivered.

What's the stamp system?

Children earn digital stamps for writing to pen pals in different countries or taking part in special kindness campaigns. It's a way to celebrate curiosity and care — not manipulate attention.

Is this just for fun, or is it educational?

Children get to practice writing, learn about geography, and build empathy — all through real, patient communication. Stamplo is also designed so schools and teachers can use it to support literacy and cultural awareness.

Why doesn't Stamplo work properly on Amazon Fire tablets?

Amazon Fire tablets use a built-in browser (called Silk) that unfortunately doesn't support text input reliably. This can cause the keyboard to disappear when a child tries to write a letter — making it frustrating or impossible to use.

Stamplo works best on family laptops, school Chromebooks, or tablets that support the Google Play Store and child-safe browsers like Chrome with Family Link.

We don't recommend giving children unrestricted internet access. If you're using a Fire tablet and run into issues, we suggest switching to a device where you (the parent) can install approved software, create child profiles, and control app usage.

Can schools or organisations use Stamplo?

Yes. Schools, home education groups, companies and community organisations can create a private Stamplo network for their families. Children within the organisation discover each other rather than the wider community, while all parental approval and safety protections remain in place.
