Terms of use

Last updated: 4 October 2026.

Purpose and acceptance

Engineering Desk Tools provides free calculators, guides and downloadable maintenance records for learning, preliminary estimates and recordkeeping. By using these resources, you agree to these terms. If you do not agree, stop using the resources.

Use at your own risk

You are responsible for the inputs you enter and for checking whether each method applies to your equipment and operating conditions. Results depend on assumptions that may not match an actual installation. Verify any design, purchasing, maintenance or operating decision with applicable standards, equipment documentation and appropriately qualified personnel.

No professional certification

A calculation, download or guide is not a professional engineering service, approval, inspection, calibration certificate or safety assessment. It does not certify compliance or replace a qualified review. No accreditation or manufacturer approval is implied.

Accuracy and availability

We aim to provide useful, checked calculations but do not guarantee accuracy, completeness, suitability or uninterrupted availability. Sources, equipment details and requirements can change. Report possible errors through the Contact page.

Responsibility and limitations

To the extent permitted by applicable law, the site owner is not responsible for losses arising from reliance on these resources, including equipment damage, production loss or incorrect decisions. Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded.

Templates, reuse and attribution

You may download and adapt the free templates for your own maintenance records. You may share links to the website and embed the supplied calculators with the included attribution. Do not redistribute the complete website or represent its content as your own. Third-party materials remain subject to their owners’ rights.

External links and advertising

Linked websites have their own terms and privacy practices. A link or advertisement is not an endorsement or technical approval of a product. Paid relationships, if introduced, will be disclosed.

Changes and contact

These terms may be updated as the site develops. Questions can be sent to ah14600146@gmail.com. See our privacy policy for information about data and cookies.
