Children’s privacy

Last updated 23 August 2026

Meseretna is built for children, which changes what is reasonable to collect. The design rule throughout is that a child profile is a place to learn, not an account: it has no login, no email address, no way to be contacted, and no presence outside the family that created it.

An adult owns the account

Only an adult can create an account, and child profiles are created inside it. That adult can see everything a child has done, change or delete any profile, and close the account entirely. A child cannot reach billing, security settings or anyone else’s data.

What a child cannot do

• Message another user, or be messaged by one.
• Be seen by anyone outside your household. First names appear only on your own family leaderboard.
• Publish anything to the open internet.
• See advertising, because there is none anywhere in the product.
• Upload a photo that anyone outside the family can see.

Voice recording

Pronunciation practice can record a child speaking so they can hear themselves against the model pronunciation. That recording is held in the browser for the length of the exercise and is never uploaded, never stored, and never reaches us. The safest place for a recording of a child is nowhere, so that is where it goes.

Photos

A photo on a child’s dashboard is optional and off by default — an emblem is used instead. If one is added it is resized in the browser before upload, which strips camera metadata including any location the original photo carried. It appears on that child’s own dashboard and nowhere else, and can be removed in one tap.

Your rights as a parent

You can see, correct, export or delete everything held about your child, at any time, from your account. You do not need to ask us, and you do not need a reason. Export gives you a JSON file of every profile, every word learned and every post; closing the account deletes all of it immediately, with no copy kept and no grace period. Both live under Account → Security. If you would rather we did it, get in touch and we will confirm when it is done.

Where this needs a lawyer, and where it does not

Everything above is a factual description of how the software behaves, and we are confident in it. Whether the service meets every obligation of COPPA in the United States, UK-GDPR, or the equivalent rules wherever your family lives is a legal question, and one being reviewed by counsel before we advertise. If you need a formal answer for your own compliance reasons, ask us rather than relying on this page.
