Terms of Use
Last updated 26 September 2026
These terms are short because OmniTools is a free calculator with no accounts and no data collection. If anything here is unclear, ask us before relying on it.
What OmniTools provides
OmniTools provides free online calculators and converters for informational and general reference. No account is required and no fee is charged. We may add, change, or remove tools at any time, and we do not guarantee that any tool will remain available or unchanged.
Not professional advice
Nothing on this site is financial, legal, tax, accounting, medical, or investment advice. Results are calculations based on the inputs and assumptions you provide, and on the rates, definitions, and methods described on each tool page.
Tax rates, interest rates, thresholds, and regional definitions change. We update these where we become aware of changes, but we cannot guarantee that the information is current or complete at the moment you read it. Verify anything that affects a financial, legal, or regulatory decision against an authoritative current source, and consult a qualified professional where appropriate.
To the fullest extent permitted by law, OmniTools and its operators are not liable for any loss or damage arising from reliance on the output of any tool, including indirect or consequential loss.
Your data
Tools execute in your browser and your inputs are not transmitted to or stored by us. You are responsible for the accuracy of the values you enter and for the decisions you take based on the output. Please do not use any tool as the sole basis for a decision with legal, financial, or safety consequences.
Acceptable use
You may use OmniTools for personal or commercial purposes. You may not attempt to disrupt the service, probe it for vulnerabilities without written permission, scrape it at a rate that degrades it for others, or use it to distribute malware or unsolicited communications.
Intellectual property
The OmniTools name, site design, and written content are the property of ullass. The underlying calculation methods are standard arithmetic and publicly known formulae, which are not claimed as proprietary. You may link to any page and quote short extracts with attribution.
Advertising
The site is supported by third-party advertising. We do not control advertiser content or the links it contains, and the appearance of an advertisement does not imply endorsement. We are not responsible for transactions entered into with any advertiser.
External links
Links to other ullass products and to third-party references are provided for convenience. We are not responsible for the content, accuracy, or practices of sites we do not operate.
Changes to these terms
These terms may be updated. The revised version will be published on this page with an updated date. Continuing to use OmniTools after a change means you accept the revised terms.
