Privacy

Last updated 23 August 2026

Meseretna is used by children, so this page is written to be read by a parent in a few minutes rather than by a lawyer in an hour. It describes what the service actually stores, which we have taken directly from the database schema rather than from a template.

The short version

  • No advertising, and no advertising or tracking pixels of any kind.
  • No selling or sharing of personal information with data brokers.
  • No child email addresses, phone numbers, or home addresses.
  • No location data.
  • No microphone access unless a parent uses the pronunciation practice, and those recordings stay in the browser and are never uploaded.
  • No public profiles, and no way for a stranger to contact a child.

What we hold about each child

A child does not have their own login or email address. They exist as a profile on your account, and everything below is visible to your family and to nobody else outside it.

WhatWhyWho can see itHow long
First nameSo the app can greet them and the parent can tell profiles apart.Your family. First name only appears on the family leaderboard.Until you delete the profile.
Photo, if you add oneShown on their own dashboard. Entirely optional — an emblem is the default.Your family only. Photos never appear on the leaderboard or the learners list.Until you remove it or delete the profile.
Progress: which words and letters are knownThis is the product. Adaptive practice cannot work without it.Your family.Until you delete the profile.
Lesson answers and timingsDeciding what to teach next and what needs review.Your family.Until you delete the profile.

Who else is involved

Running the service means a small number of companies necessarily handle some data on our behalf. We do not add any others for analytics or advertising.

Vercel
Hosting and content delivery. Standard web request logs.
Neon
The database. Everything stored above, encrypted at rest.
Stripe
Payments. Billing details. Card numbers never reach Meseretna.
Resend
Sending email. Your email address and the message.

Deleting things

You can remove a child’s photo at any time from their dashboard, and delete a child profile or the whole account from your account settings. Deleting a profile removes that child’s progress with it. Deleting the account removes everything in the tables above.

If anything does not delete the way this page says it should, that is a bug and we want to hear about it — tell us.

Children’s privacy

There is a separate page for children’s privacy covering parental consent, what a child can and cannot do in the app, and how to exercise your rights over their data.

Changes

If this page changes in a way that affects what we collect or who sees it, we will email the address on the account before the change takes effect.
