About these terms
These Terms of Service apply when you access or use Calculum. The service is operated by Flavio Copes, Italy. By using the site, you agree to these terms. If you do not agree, do not use the site. Questions about these terms can be sent to[email protected].
What Calculum provides
Calculum provides calculators, estimates, examples, and explanatory material for general informational and planning purposes. The service is currently provided without charge and without user accounts. Features may be added, changed, suspended, or removed over time.
No professional advice
Calculum does not provide financial, investment, legal, tax, accounting, medical, insurance, engineering, construction, safety, employment, or other professional advice. Results are estimates based on the inputs and assumptions shown. You remain responsible for verifying inputs, formulas, current rules, and results before making a decision. The site's Disclaimer forms part of these terms.
Permitted use
You may use Calculum for lawful personal, educational, or internal business purposes. You may link to its public pages and use calculator results in your own work, provided you do not misrepresent Calculum or imply an endorsement or professional opinion.
Prohibited use
You must not:
- use the service in violation of law or another person's rights;
- attempt to bypass security controls or gain unauthorized access to systems or data;
- introduce malware or use the service to distribute harmful material;
- interfere with the site's availability or place an unreasonable load on it; or
- present Calculum's content or identity as your own or falsely claim an affiliation.
Intellectual property
The site, its original text, design, branding, and software are owned by the operator or used with permission and are protected by applicable intellectual-property laws. These terms give you a limited, non-exclusive, revocable right to access and use the service as described above. They do not transfer ownership of the service or its content.
Third-party information and links
Calculum may refer to laws, rates, standards, products, or websites maintained by third parties. Those resources can change, and Calculum does not control their availability, content, or privacy practices. A link does not imply endorsement.
Privacy
The Privacy Policy explains how calculator inputs, browser storage, analytics, and technical request data are handled.
Availability and warranties
Calculum is provided “as is” and “as available.” To the fullest extent permitted by law, no warranty is made that the site will always be available, secure, error-free, complete, current, or suitable for a particular purpose. Nothing in these terms limits a warranty or consumer right that applicable law does not allow to be excluded.
Limitation of liability
To the fullest extent permitted by applicable law, the operator will not be liable for indirect, incidental, special, consequential, or business losses arising from use of, or inability to use, Calculum. Nothing in these terms excludes or limits liability that cannot legally be excluded or limited, including any mandatory consumer remedies.
Ending access
You may stop using Calculum at any time. Access may be restricted or blocked where reasonably necessary to protect the service, its users, or others; respond to unlawful or abusive use; or comply with legal obligations.
Changes to these terms
These terms may be updated to reflect changes to the service or applicable requirements. The updated version applies from the date shown above. If you continue using Calculum after an update, the updated terms apply to that use.
Governing law and disputes
These terms are governed by the laws of Italy, without depriving consumers of mandatory protections provided by the law of their country of residence. Courts will have jurisdiction as determined by applicable law. Before starting a formal claim, you are invited to contact the operator so the issue can be addressed directly.
General
If a provision of these terms is found unenforceable, the remaining provisions continue to apply. A failure to enforce a provision is not a waiver of it. These terms, together with the Privacy Policy and Disclaimer, are the entire agreement concerning your use of the service.
