1. Our Purpose

Tool Driver aims to provide practical online utilities and supporting information that visitors can understand and use for everyday tasks.

This policy explains our intended approach to tool checks and content quality. The depth of testing and review may vary depending on a tool’s function, complexity and potential impact.

2. How Tools May Be Tested

Where appropriate, a tool may be reviewed using a combination of checks such as:

• Testing whether required inputs are accepted correctly.
• Comparing sample outputs against independently calculated or expected results.
• Checking boundary values and common input mistakes.
• Reviewing error handling and output formatting.
• Testing different valid input combinations.

Not every tool will have undergone every check. Testing should be proportionate to the tool’s purpose and limitations.

3. Formulas, Calculations and Conversions

For calculators, appropriate checks may include reviewing the intended formula, testing known examples and checking rounding or boundary conditions.

For unit converters, relevant checks may include comparing conversion factors with recognised references and verifying that source and destination units are handled correctly.

Some tools depend on conventions, estimates or assumptions. Where relevant, these should be explained so users can judge whether a result fits their situation.

4. Editorial Standards

Our intended editorial approach is to make content clear, relevant and useful to the task it addresses.

• Explain the main question or purpose directly.
• Use clear headings and straightforward language.
• Include examples when they help explain a process.
• Distinguish general information from estimates and assumptions.
• Avoid unsupported claims about accuracy, certification or testing.
• Review information when meaningful errors or changes are identified.

5. Sources and Assumptions

When a tool or article depends on external facts, standards, formulas or conversion factors, relevant reliable references should be considered during review.

Not every tool requires the same source material. Some simple utilities rely on standard operations, while others may depend on assumptions or information that can change over time.

Visitors should review any explanations and caveats shown on the individual tool page before relying on an output.

6. Errors, Feedback and Corrections

We recognise that online tools and published information may contain errors or need improvement. Reports from visitors can help us identify issues that were not previously noticed.

When reporting an issue, include the relevant page URL, sample inputs, the displayed result and the expected result where possible.

Reported issues may be reviewed and corrected where appropriate. The timing and outcome depend on the nature of the issue and available information.

Use our Contact page to report a problem.

7. Limitations and Professional Advice

Testing does not guarantee that a tool will be error-free or appropriate for every situation. Results may depend on inputs, formulas, rounding, technical limitations or assumptions.

Do not treat general-purpose calculators as a substitute for qualified medical, financial, legal, engineering or other professional advice. Verify important results independently.

Read our Disclaimer for further information.

8. Feedback and Policy Updates

We may revise this policy as our tools, review practices and website features develop. Updated information will be published on this page.

Suggestions about testing, content clarity or accuracy can be submitted through our Contact page.
