Terms of use

By using nTools, you agree to use the site lawfully and responsibly. If you do not agree with these terms, do not use the site.

Purpose of the service

nTools provides free general-purpose calculators, converters, validators and reference utilities. Results are generated from the values you enter and are intended for convenience and information, not as professional advice.

Your responsibility

Check important results independently before relying on them. You are responsible for the data you enter, how you interpret an output and any decision you make from it. Do not enter confidential, unlawful or third-party personal data unless you are authorised to process it.

Financial, tax, legal and security decisions

Calculators use generic mathematical rules and user-supplied rates. They do not determine the tax, law, contract, network policy or financial product that applies to you. Validators check formats or check digits only and do not prove identity, ownership, authenticity or official status. Seek qualified advice or an official source for important decisions.

Acceptable use

Do not misuse the site, attempt to bypass security or rate limits, overload endpoints, probe systems without permission, distribute harmful content, or use the service in a way that infringes another person’s rights. Automated access must remain reasonable and comply with applicable law.

External services

Some functions rely on Cloudflare, Google, RDAP.org, DNS resolvers or ViaCEP. Their availability, accuracy and processing are governed by their own terms and policies. nTools does not control their responses.

Availability and changes

The service is provided as available and may change, be limited or become temporarily unavailable without notice. We may correct results, add or remove tools, or restrict abusive use.

Intellectual property

The nTools name, interface and original site content may not be copied or presented as another service without permission. Open-source components and dictionaries remain subject to the licences supplied with them.

No warranty and limitation

To the extent permitted by law, nTools makes no guarantee that every result is complete, current or error-free and is not liable for indirect loss caused by reliance on the service. Nothing in these terms excludes rights or liability that cannot legally be excluded.
