Disclaimer

General

The information and tools on Expert Tools Kit are provided for general informational purposes only. While we take considerable care over correctness — the conversion factors are exact where a definition exists, the financial formulas are the standard ones, and the tax rates are checked against official sources — we make no representation or warranty as to accuracy, completeness or currency.

Not professional advice

Nothing on this site constitutes professional advice, and you should not treat it as a substitute for consulting a qualified professional.

Financial and tax

The loan, VAT, sales tax and ad revenue calculators produce estimates based on the figures you enter and the standard formulas. They do not account for your circumstances, jurisdiction-specific rules, fees, insurance, escrow, exemptions, thresholds, cross-border rules or changes in law. Tax rates change and vary by locality. Consult a qualified accountant, tax adviser or financial adviser before acting on any figure produced here. We are not authorised to give financial advice in any jurisdiction.

Health

The BMI calculator is a general population-level screening measure, not a diagnostic tool. BMI does not distinguish muscle from fat, does not account for fat distribution, and its thresholds differ by ethnicity, age and life stage. It is not appropriate for children, pregnant people, or athletes. Do not use it to make decisions about your health. Consult a doctor or a registered dietitian.

Legal

The date, age and robots.txt tools produce results that may bear on legal deadlines, eligibility or compliance obligations. They are not legal advice. Statutory deadlines, notice periods and limitation periods have jurisdiction-specific rules about how days are counted and which days are excluded. Consult a qualified lawyer.

Accuracy of tool output

Tools may produce incorrect results due to browser differences, unusual input, malformed files, or a bug we have not found. Always:

• Keep a backup of any original file before processing it. Our tools never modify your original, but your own subsequent steps might.
• Verify the output before relying on it — open the merged PDF, check the compressed image, confirm the calculation independently.
• Do not use output in a safety-critical, medical, legal or financial context without independent verification.

Availability

We do not guarantee that the Service will be available, uninterrupted, or free of errors. Tools may be modified or withdrawn without notice. Browser API changes can break a tool without warning.

External links and advertising

This site displays third-party advertising and contains outbound links, some of which are affiliate links marked as sponsored. We do not endorse, control or take responsibility for third-party content, products or services. Any transaction you enter into with a third party is solely between you and them.

Fair use of downloaded content

Some tools retrieve publicly available content, such as YouTube video thumbnails. Downloading such content does not transfer any rights in it. Copyright in third-party material remains with its owner, and it is your responsibility to ensure your use is lawful — whether under fair use in the United States, fair dealing in the United Kingdom and Canada, or the relevant exception in your jurisdiction.
