Acceptance of Terms
By accessing and using blockly.dev, you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use our service.
Description of Service
blockly.dev is a free, non-profit educational platform offering 64 interactive lessons with visual block-based programming and audio explanations. All lessons are available at no cost to anyone with an internet connection. There are no paid plans, subscriptions, or premium tiers.
User Accounts
An account is optional — you can complete every lesson without signing in. If you do create an account (to sync progress across devices), you are responsible for maintaining the confidentiality of your credentials and for activities that occur under your account.
Cost
blockly.dev is provided free of charge. We do not sell the course, do not run subscriptions, and do not collect payment information. The project is supported by volunteers and voluntary donations.
Intellectual Property
All content on blockly.dev, including lessons, audio, images, and code, is owned by its respective creators and made available for educational use. You may not republish large portions of the course commercially without permission.
Termination
We reserve the right to suspend an account that abuses the service. The free lessons themselves remain publicly accessible.
Limitation of Liability
blockly.dev is provided 'as is' without warranties of any kind. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service.
