Privacy notice
Last updated 23 October 2026
Hatchlands is a maths game for children in Years 3 to 6. This notice explains in plain English what information the game holds, why, who sees it and what your choices are. It is written for parents, carers, teachers and children's families. If something here is unclear, please ask us.
Who we are
Hatchlands is run by Boba Education (bobaeducation.com). For information about a family account that a parent or carer makes, we decide how the information is used (we are the "controller" under UK data protection law). For players that a teacher adds to a school class, the school decides to use Hatchlands and we look after the information on the school's behalf (we are the "processor"), so please also read the school's own notice. You can contact us at contact@bobaeducation.com.
What we collect
| Who | What we hold |
|---|---|
| Parents and carers | Your email address (so we can send a sign-in link), and the nicknames and PINs you choose for your children. |
| Teachers | Your school email address, an optional display name, your class names and the first names (or nicknames) of the pupils you add. |
| Children (players) | A nickname (we ask for a first name only, never a surname), the pets, coins and stages in the game, settings such as year group and chosen topics, and counts of right and wrong answers and battles. A PIN, if one is set, is stored scrambled so nobody can read it back. |
| Everyone | A sign-in cookie, and short-lived technical records such as the network address a request came from, which our hosting provider and our security checks use to keep the service running and to stop abuse. |
What we do not collect: children's email addresses, surnames, photos, voices, locations, messages or a list of every answer given. Hatchlands has no chat and no way for players to contact each other.
Why we use it
- To run the game: to remember a child's pets and progress, and to check answers and rewards on our server.
- To let parents and teachers sign in, by sending an email link.
- To show a teacher how a class is getting on (pets collected, stages cleared, right and wrong answers).
- To keep the service secure and fair, for example to limit repeated guesses of a PIN.
We use this information only for these purposes. We do not sell it, we do not use it for advertising, and we do not use it to build a profile of a child.
The lawful basis
For parents and carers who make an account, we use your information to provide the service you asked for (a contract) and in our legitimate interest in keeping it secure. For school classes, the school relies on its own lawful basis for using an educational tool, and we follow the school's instructions.
Who we share it with
- Cloudflare, which hosts the game's website and stores its database. The database is held in Western Europe.
- Resend, which sends the sign-in emails (your email address and the link).
These companies act only on our instructions. We do not share information with anyone else, except where the law requires it. A teacher can see the nickname and progress numbers of pupils in their class, and nothing else about them.
Cookies and browser storage
Hatchlands uses one essential cookie to keep you signed in. It cannot be read by scripts and is only sent to Hatchlands. A guest player's save, and the sound settings, are kept in your browser's own storage on your device. We do not use advertising, analytics or tracking cookies.
How long we keep it
We keep an account until it is deleted. A parent can delete a child or the whole family account at any time, and a teacher can delete a pupil or their account (pupils a family has claimed stay with the family). When something is deleted it is removed from our database. Expired sign-in links, codes and sessions are cleaned up automatically. If you would like an account removed and cannot do it yourself, email us and we will do it.
Your rights
Under UK data protection law you can ask us to show you the information we hold, correct it, delete it, or restrict or object to how we use it. A parent can download everything we hold about their child from the "Manage" screen, and delete it there too. If you are not happy with how we have handled your information you can complain to the Information Commissioner's Office (ico.org.uk), though we would like the chance to put things right first.
Children
Hatchlands is designed with the ICO's Children's Code in mind: we ask for very little, there is no chat or sharing between players, no adverts, no pressure to play for long, and nothing that can be bought makes a pet stronger. A class is only ever a link to a child's player, never its owner, so a child who leaves a class keeps everything. A school player can be claimed by a family with a code from the teacher.
Changes
If we change how we use information in a way that matters, we will update this page and the date at the top, and tell account holders when it affects them.
