Who we are
OpenToolBase (opentoolbase.com) is operated by Studio Dreamhop, an SRL registered in Belgium under enterprise number 0770.297.487. Contact: hello@opentoolbase.com.
What these tools are
OpenToolBase provides free, interactive calculators for pricing and budgeting decisions. They are information tools, not professional advice. The results depend entirely on the numbers you enter and on simplified models whose formulas are published on each page. They do not replace an accountant, a tax advisor, a lawyer or a financial professional, and decisions you make based on the results are your own.
Acceptable use
You may use the tools freely, for personal or commercial purposes, and share links to them (including links that carry your input values). You may not scrape, resell or misrepresent the tools as your own, attempt to disrupt the service, or use it for anything unlawful.
Intellectual property
The site's content, design, code and branding belong to Studio Dreamhop or its licensors. The numbers you type in are yours; we don't receive them.
No warranty
The tools are provided "as is", free of charge. We work to keep the formulas correct and the service available, but we make no guarantee of accuracy, availability or fitness for a particular purpose, and we accept no liability for decisions made based on the tools' output, to the extent permitted by Belgian law.
Changes
We may update the tools, their formulas or these terms at any time. Each tool page shows when its methodology was last updated.
Governing law
These terms are governed by Belgian law. Any dispute falls under the jurisdiction of the courts of Brussels, Belgium.
