By accessing OpenCalculator you agree to these terms. If you do not agree, please do not use the site.
All tools are provided free of charge for personal and commercial use (for example, generating a QR code for your shop). You may not resell, repackage or redistribute our tools or content as your own service.
We work hard to keep our calculators accurate, but results are provided for general informational purposes only and may not reflect every fee, tax rule or edge case. Always verify important figures — loan terms, tax amounts — with your bank, accountant or official sources before acting on them.
You agree not to misuse the site: no attempting to disrupt it, scrape it aggressively, or use generated content (such as QR codes) for fraud, spam or any unlawful purpose.
The site's design, text content and branding are owned by OpenCalculator. Tool outputs you generate (your QR codes, your compressed images, your passwords) belong to you.
The site is provided "as is" without warranties of any kind. To the maximum extent permitted by law, we are not liable for any loss or damage arising from use of the tools.
We may update these terms at any time; continued use of the site means you accept the updated terms.
