Privacy policy
The short version: this site is used by children, so it is built to collect as little as possible. There are no accounts, and your practice results never leave your device.

What we store, and where
Your scores, medals, chosen tables and light or dark preference are saved in your browser's own local storage. That data stays on the device you used, is not sent to us, and is not linked to a name, an email address or an account. Clearing your browser data removes it, and so does the "Reset progress" button on the site.
Accounts
There are none. You cannot sign up, and we never ask a child for a name, an age, an email address or a photograph. The name typed onto a printable diploma is used only to draw that certificate in your browser and is never transmitted or stored.
Cookies
We do not set advertising or tracking cookies. The site uses local storage rather than cookies for your preferences, and Laravel may set a single session cookie that is needed for the site to function.
Analytics
We measure aggregate traffic — how many people visited a page, roughly where in the world from, and which pages they came from — so we know which parts of the site are worth improving. These measurements are aggregated and are not used to build a profile of an individual visitor, and they are kept separate from advertising.
Children
This site is intended for children to use, which is precisely why it asks nothing of them. We do not knowingly collect personal information from anyone, of any age. If you believe a child has somehow sent us personal information, contact us and we will delete it.
Third parties
Fonts, styles and scripts are served from this domain rather than from a third-party CDN, so loading a page does not hand your IP address to another company. We do not sell, rent or share visitor data.
Your rights
Because we hold no personal data about you, there is nothing for us to show you, correct or delete. The data that exists is in your own browser and is under your control. If you have a question about any of this, please get in touch.
Changes to this policy
If this policy changes we will update the date at the top of this page. Continued use of the site after a change means you accept the revised policy.
