Terms of use

Last updated: 11 August 2026.

1. The service

calc-hub.net provides free online calculators and articles, operated by dionics media UG (haftungsbeschränkt), Burgdorf, Germany — see the imprint. No account is needed, nothing is for sale.

2. Results are not advice

Calculator results are simplified estimates for information and education only. They are not financial, tax, legal, medical or nutritional advice, and they must not be the basis for a financial commitment or a health decision. Real loan terms, taxes, health metrics and project costs depend on factors a general-purpose calculator cannot know. Consult a qualified professional before acting.

3. No warranty

The calculators are provided as is. We work to keep formulas correct and current, but do not warrant that any result is accurate for your situation, or that the site is available without interruption.

4. Acceptable use

No scraping the site wholesale, no probing or overloading it, no framing it to misrepresent its origin.

5. Liability and law

We are liable without limitation for intent, gross negligence and injury to life, body or health; for simple negligence only for breach of cardinal duties, limited to typical foreseeable damage — and, this being a free service, the statutory liability standards for gratuitous services apply. German law, excluding conflict-of-law rules. These terms may change with effect for the future; the date above changes when they do.
