1. Acceptance
These terms are between you and KIROEX LTD, the company that provides Excel Formula Trainer. By accessing this website or using Excel Formula Trainer, you agree to these terms. If you do not agree, do not use the website or app.
2. Using the app
Excel Formula Trainer is provided for learning and personal use. You may use the app on devices you own or control, subject to the applicable app-store rules. You may not attempt to misuse, interfere with, unlawfully copy, resell, or misrepresent the app or its content.
3. Using the website
You may browse and link to public pages for lawful purposes. You may not use the website in a way that disrupts availability, bypasses security, introduces malicious code, or infringes another person’s rights.
4. Educational content
Lessons and exercises describe how Microsoft Excel behaves in recent versions. Some functions, particularly dynamic arrays, are not available in older releases. Excel behaviour can also differ by platform, version, locale, workbook configuration, and data.
Always verify results against your own workbook before relying on them for employment, business, accounting, tax, financial, academic, or other important decisions. Financial-formula lessons are educational spreadsheet content, not financial advice or a financial service.
5. Intellectual property
The app, website design, original lesson text, exercises, and product branding are protected by applicable intellectual-property laws. These terms do not transfer ownership of that material to you. Formula names, generic syntax, and third-party marks remain subject to their respective rights.
6. Availability and changes
Features, catalogue content, system requirements, and availability may change. The website or app may be updated, suspended, or discontinued where reasonably necessary. Progress stored only on your device may be lost if app data is cleared, the app is uninstalled, or a device fails.
7. No warranty
To the maximum extent permitted by law, the website and app are provided “as is” and “as available,” without warranties of accuracy, completeness, fitness for a particular purpose, non-infringement, or uninterrupted operation. Nothing in these terms excludes a warranty or consumer right that cannot legally be excluded.
8. Limitation of liability
To the maximum extent permitted by law, the authors and publisher are not liable for indirect, incidental, special, consequential, or business losses arising from use of, or inability to use, the website, app, or educational information. This limitation does not apply where liability cannot legally be limited.
9. Third-party services
Links to app stores or other third-party services are provided for convenience. Those services operate under their own terms, privacy policies, availability, and security practices.
10. Trademarks
Microsoft and Excel are trademarks of Microsoft Corporation. Excel Formula Trainer is an independent learning tool and is not affiliated with, endorsed by, or sponsored by Microsoft. Use of third-party names is descriptive and does not imply endorsement.
11. Governing terms and severability
Mandatory laws in your place of residence may apply. If a provision of these terms is found unenforceable, the remaining provisions continue to apply to the extent permitted by law.
12. Company information and contact
