Privacy policy

DayOneCode is made for beginners of every age, children included, so we collect as little as possible: nothing that identifies anyone, 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.

The practice computer

The files, folders and terminal in the lessons are pretend. They live in your browser while you use them. What you type in the practice terminal is never sent anywhere, and nothing in a lesson can read or change the real files on your computer.

What stays on your device

Lesson stars, your progress, an optional first name for the greeting, and settings such as sound on or off are saved in your browser's local storage, on your device only. We cannot see them. Clearing your browser data removes them.

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.

Links to other sites

A few pages link to our sister sites, TypePlay and AbacusPlay, which have their own privacy policies. The lessons themselves do not link away from DayOneCode.

Contact

Questions about privacy: help.TypePlay@outlook.com. 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.
