What a child can reach, and what can reach a child

Money

• No ads in the child app of any kind, including ads for our own paid plans.
• Nothing to buy. Coins are earned in rounds and spent on parts for a ship. They cannot be bought with money.
• A locked chapter shows no price and no button. It tells the child to ask their grown-up, and stops there.

Contact

• Numbula has no chat, no comments, no messages and no photographs.
• Only a coach can make a crew. A child from another account joins only when their own grown-up enters the crew's code in the grown-up area and the crew leader approves them. A code stops working after 7 days.
• A crew ends when its crew leader's account is deleted, and every child in it loses their place, children from other families too. Each child's own answers, stars and progress stay on their own account.
• Other children see a child only by a ship name. Numbula makes it up from two words, like Swift Comet. No other ship on the account or in its crews has the same one. The grown-up can press Another name for a new one, when adding the child or later in the child's settings. Nobody can type a ship name, so a real name can never become one. The child cannot change it.
• Other children in a crew see the whole ship name.
• The app never shows a child another child's real name, age or location.

Content

• Every screen is numbers, characters and plain instructions. The only words typed by one family that another family's child can see are crew names.
• No character is a villain. Nothing chases, attacks or has to be beaten.
• Nothing flashes, and no motion runs faster than 3 Hz.
• A wrong answer is never marked red, and nothing is taken away from a child for being slow.

Data

• We sell no data, ever. The child app has no advertising and nothing from another company. It counts how often each screen and a few buttons are used, as daily totals that carry no name, account or device.
• For each child we hold the name their grown-up typed, an age band, a ship name, their settings, a record of their answers, and any note sent with Tell us while they played. No email address, no phone number, no location, no device advertising ID.
• The privacy notice lists what we hold and who can see it, in plain English.
• Sign-up asks the grown-up to check a box saying they are 18 or over and the child's parent or guardian, or an adult with the parent's or guardian's permission, then to type a code we email them to agree before they add a child. From Settings in the grown-up area they can download everything we hold, or close the account.
