The ground rules

Plain-language terms for families using Kidifly. Last updated 12 October 2026.

Who may use Kidifly

Accounts are for adults. A parent or legal guardian signs in with their OneVault ID and may create up to three child profiles for children in their care. Children use Kidifly only through a profile their parent created, and the parent is responsible for that use.

What is free and what is paid

Every lesson and every level (Easy, Medium and Hard) is free. Kidifly Pro, when it opens, adds model papers, timed quizzes, printable worksheets and progress reports for a yearly fee shown on the Pro page at the time of purchase. Prices, refunds and renewal terms for Pro will be stated before any payment is taken; nothing is charged until then.

Content and curriculum

Lessons are original Kidifly work designed to practise objectives from the England National Curriculum and Cambridge Primary frameworks, which Pearson Edexcel iPrimary is based on. Kidifly is not affiliated with, endorsed by or a substitute for any school, examination board or publisher, and does not guarantee any examination result or learning outcome.

Acceptable use

Do not share your account or let an adult other than a parent or guardian use a child profile.
Do not scrape, crawl, copy, download in bulk, reverse engineer or resell Kidifly lessons, artwork, audio or code, or use them to build a competing product.
Do not attempt to access other families’ information or the control panel.
Do not use Kidifly for anything unlawful.

We may suspend accounts that break these rules.
