About Tool Orchard
Why Tool Orchard exists and how its free online tools are designed.
Useful tools without unnecessary barriers
Tool Orchard is a growing collection of practical calculators, converters, word-game helpers and digital utilities. The aim is straightforward: let someone open the right tool, complete a task and move on without creating an account.
How the tools work
Most calculators and converters run directly in the browser. Some word-game searches send the entered letters or puzzle clues to the Tool Orchard server so it can search a larger dictionary and return matching words. Tool Orchard does not create user profiles or save a personal history of completed calculations.
Free to use
The tools are available without payment or registration. The site is intended to be supported by clearly labelled advertising. Advertising should never be disguised as a tool control or interfere with the result.
Accuracy and improvement
Every tool is designed as a practical guide, but no automated result is suitable for every situation. Financial decisions, electrical work, RF engineering, medical matters and manufacturer-specific sizing should be checked with an appropriate professional or authoritative source.
