Privacy policy

AbacusPlay is made for children, so we collect as little as possible: nothing that identifies a child, and nothing we do not need.

What we do not collect

• No accounts, names, email addresses, birthdays or photos. There is nothing to sign up for.
• No personal information from children under 13 (or any age). We follow the spirit and the letter of the US Children's Online Privacy Protection Act (COPPA).
• No advertising cookies, no ad tracking and no selling or sharing of data.
• No analytics cookies at this time. If we add privacy-friendly visit counting later, this page will say so first.

What stays on your device

Lesson stars, your progress, the sound on or off setting and the first name typed in the welcome pop-up (so PlayBuddy and PlayType can greet you) are saved in your browser's local storage, on your device only. We cannot see them. Clearing your browser data removes them. A name typed on a worksheet is only printed on the page; it is not saved or sent anywhere.

What our host sees

Like every website, the pages are delivered by a hosting service (Cloudflare). Their servers handle standard technical information such as IP addresses to deliver pages and protect the site from attacks; we do not use it to identify visitors.

Two other services deliver parts of the pages, and like any host they see the IP address of the device that asks: Google Fonts sends the icon font, and when the live voice is used, its code comes from jsDelivr (cdn.jsdelivr.net) and its voice model from Hugging Face. They receive nothing else from us.

Links to other sites

Every page's footer, and a section of the home page, link to our sister sites TypePlay (typeplay.org) and DayOneCode (dayonecode.com). They are free learning sites from the same team, with their own privacy policies.

Contact

Questions about privacy: [email protected]. Parents can ask us anything about how the site handles their child's use; the short answer is that we hold no data about them.
