Terms of Service

The legally binding terms governing your use of CALCULATORPRO.io, our calculators, APIs, embeds, and content.

ET By Editorial Team Last updated June 3, 2026

These Terms of Service ("Terms") form a legally binding agreement between you ("you", "user") and CALCULATORPRO.io ("we", "us", "our") governing your access to and use of the calculatorpro.io website, calculators, APIs, articles, embeds and related services (collectively, the "Services"). By accessing or using the Services you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not use the Services.

1. Eligibility

You must be at least 13 years old (or 16 in the EEA/UK) to use the Services. By using the Services you represent that you meet this requirement and that you have the legal capacity to enter into these Terms. If you use the Services on behalf of an organisation, you represent that you have authority to bind that organisation.

2. The Services

The Services provide free online calculators and reference content for informational and educational purposes only. We may add, modify, suspend or discontinue any calculator, feature or content at any time without notice. We may also impose limits on certain features or restrict access without liability.

3. Not professional advice

Calculator outputs and accompanying content are not financial, investment, tax, legal, medical, accounting, engineering or other professional advice. They are general estimates based on inputs you provide and assumptions described in the page content. Tax rates, interest rates, regulations and medical guidelines change frequently and may not be reflected in every calculator at every moment. Always consult a qualified professional before making decisions that could affect your finances, health, taxes or legal situation. You use the Services at your own risk.

4. Acceptable use

You agree not to:

  • Use the Services for any illegal, harmful, fraudulent or infringing purpose.
  • Reverse-engineer, decompile or attempt to extract source code, except to the extent permitted by law.
  • Scrape, mirror, frame, crawl or harvest the Services or their content at a rate or volume that interferes with normal operation, or in violation of robots.txt.
  • Use automated means (bots, scripts) to interact with the Services except as expressly permitted by a documented API.
  • Probe, scan or test the vulnerability of the Services or breach security or authentication measures.
  • Upload or transmit malware, viruses, worms, or any code intended to disrupt the Services.
  • Use the Services to send unsolicited messages, spam, advertising or solicitations.
  • Misrepresent your identity, impersonate any person, or falsify information in submissions.
  • Remove, obscure or alter copyright, trademark or other proprietary notices.
  • Use the Services to violate any third party’s rights, including privacy or intellectual property rights.

Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to access and use the Services for your personal, non-commercial use, and to view, download and print individual pages for personal reference. All other rights are reserved.

You may not republish, redistribute, sell, license or commercially exploit any part of the Services without our prior written permission.

7. User submissions

When you send us feedback, calculator requests, bug reports or other content via our contact form or email ("Submissions"), you grant us a worldwide, royalty-free, perpetual, irrevocable, sublicensable licence to use, reproduce, modify and incorporate the Submission in connection with operating and improving the Services. You represent that you own or have necessary rights to the Submission and that it does not infringe any third-party rights. We are not obliged to act on any Submission.

8. Third-party services & advertising

9. DMCA / copyright complaints

We respect intellectual property rights. If you believe content on the Services infringes your copyright, please send a DMCA notice to hello.toolskit@gmail.com with the subject “DMCA Notice” including: (1) identification of the copyrighted work claimed to be infringed; (2) the URL or location of the allegedly infringing material on our Site; (3) your contact information (name, address, phone, email); (4) a statement that you have a good-faith belief that use of the material is not authorised by the copyright owner, its agent, or the law; (5) a statement, made under penalty of perjury, that the information in the notice is accurate and that you are the owner or are authorised to act on behalf of the owner; and (6) your physical or electronic signature. Misrepresentations may result in liability under 17 U.S.C. § 512(f). We may forward the notice to the alleged infringer.

10. Disclaimer of warranties

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ACCURATE, ERROR-FREE OR SECURE, OR THAT RESULTS PRODUCED BY ANY CALCULATOR WILL BE ACCURATE FOR YOUR SPECIFIC CIRCUMSTANCES. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL CALCULATORPRO.IO, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, REVENUE, DATA, USE, GOODWILL OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICES WILL NOT EXCEED ONE HUNDRED US DOLLARS (USD 100). SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF LIABILITY FOR CERTAIN DAMAGES, SO THE ABOVE MAY NOT APPLY TO YOU.

12. Indemnification

You agree to defend, indemnify and hold harmless CALCULATORPRO.io and its affiliates, officers, directors, employees and agents from and against any and all claims, damages, obligations, losses, liabilities, costs and expenses (including reasonable attorneys’ fees) arising from: (a) your use of or access to the Services; (b) your violation of these Terms; (c) your violation of any third-party right, including intellectual property or privacy rights; or (d) any content you submit.

13. Termination

We may suspend or terminate your access to the Services at any time, with or without cause or notice. You may stop using the Services at any time. Sections that by their nature should survive termination (including IP, disclaimers, limitations of liability, indemnification and dispute resolution) will survive.

14. Changes to the Terms

We may revise these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page and, for material changes, post a notice on the Site. Your continued use of the Services after the effective date constitutes acceptance of the revised Terms.

15. Governing law & disputes

These Terms are governed by the laws of the jurisdiction in which our operating entity is established, without regard to conflict-of-law principles. To the maximum extent permitted by law, any dispute arising out of or relating to these Terms or the Services will be resolved exclusively in the courts of that jurisdiction, and you consent to personal jurisdiction and venue there. Nothing in this section limits your statutory consumer rights under the law of your country of residence.

16. Miscellaneous

  • Entire agreement. These Terms together with the Privacy Policy constitute the entire agreement between you and CALCULATORPRO.io regarding the Services.
  • Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions will remain in full force and effect.
  • No waiver. Our failure to enforce any right or provision is not a waiver of that right or provision.
  • Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms freely.
