Terms

Effective 27 August 2026. By using Mechanism Playground, you agree to these straightforward terms.

An educational toy, not engineering software

The app uses a deterministic, simplified kinematic model. It does not simulate material strength, forces, collisions, manufacturing tolerances, or physical safety. Do not use its output to design real machinery, safety equipment, or load-bearing devices. Players under 13 should use it with a parent, guardian, or teacher.

Free and paid features

Free build, puzzles 1–5, local saving, offline use, and blueprint import/export are free. Forge Edition is a one-time US$4 purchase unlocking puzzles 6–10. Sociobot/Dodo is the merchant of record and handles payment and refunds. A refunded purchase revokes its license. Access may be restored on another device by pasting the license token.

Your work and acceptable use

You own the blueprint files you create. You may use the app for personal and classroom learning. Do not interfere with the service, attempt to bypass paid-feature verification, or use the product unlawfully.

Availability and liability

The app is provided “as is” without warranties. Offline support and export are provided to reduce dependence on the hosted service, but uninterrupted availability is not guaranteed. To the extent allowed by law, liability is limited to the amount you paid for the app.
