Terms and Conditions
Last updated: April 1, 2026
1. Acceptance of Terms
By accessing and using OneApp Calculators (OneApp Calculators.web.app), you acknowledge that you have read, understood, and agree to be bound by these Terms and Conditions. If you do not agree with any part of these terms, you should discontinue use of the platform immediately. These terms apply to all visitors, users, and anyone who accesses or uses OneApp Calculators.
2. Nature of Service
OneApp Calculators is a free, client-side income tax estimation tool designed for Indian taxpayers. The service runs entirely within your web browser and performs calculations based on publicly available tax slabs, rates, and provisions as defined by the Income Tax Department of India. OneApp Calculators is not a licensed tax advisory service, accounting firm, or financial institution. The calculations provided are estimates intended to aid your understanding of potential tax liabilities.
3. No Professional Advice
The information and calculations provided by OneApp Calculators do not constitute professional tax advice, financial advice, or legal counsel. Every individual's tax situation is unique and may involve complexities that a general-purpose calculator cannot address. You should always consult a qualified Chartered Accountant (CA), tax professional, or financial advisor before making tax-related decisions, filing returns, or taking any action based on calculations from this tool.
4. Accuracy and Limitations
While we strive to maintain the highest accuracy by aligning our calculations with the latest tax provisions, OneApp Calculators does not guarantee that all calculations are error-free or cover every possible tax scenario. The tool is designed for standard income tax computation and may not account for advanced situations such as capital gains taxation, income from multiple countries, agricultural income exemptions, or specialized deductions under lesser-known provisions. Tax laws are subject to change, and there may be brief periods between budget announcements and our updates.
5. Intellectual Property
All content on OneApp Calculators — including but not limited to the website design, layout, graphics, text, logos, and source code — is the intellectual property of OneApp Calculators and is protected by applicable copyright and intellectual property laws. You may not reproduce, distribute, modify, create derivative works from, or publicly display any content from this website without explicit prior written consent from OneApp Calculators, except for personal, non-commercial use such as downloading your own tax calculation summaries.
6. User Responsibilities
You are solely responsible for the accuracy of the income figures, deduction amounts, and other data you enter into the calculator. OneApp Calculators processes whatever numbers you provide without verification. Incorrect inputs will naturally lead to incorrect results. You agree not to misuse the platform, attempt to compromise its functionality, or use the results in any misleading manner. You also agree not to use automated scripts, bots, or crawlers to excessively access the service.
7. Limitation of Liability
OneApp Calculators, its creators, team members, and affiliates shall not be held liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of or inability to use the service. This includes, without limitation, any losses resulting from decisions made based on calculations provided by OneApp Calculators, errors in tax computation, or any interruption of service. Your use of OneApp Calculators is entirely at your own risk.
8. Modifications to Terms
We reserve the right to update, modify, or replace these Terms and Conditions at any time without prior notice. Changes will be effective immediately upon being posted on this page. The "Last updated" date at the top of this page reflects the most recent revision. Your continued use of OneApp Calculators after any changes constitutes acceptance of the new terms.
9. Governing Law
These Terms and Conditions shall be governed by and construed in accordance with the laws of India. Any disputes arising from or in connection with these terms shall be subject to the exclusive jurisdiction of the courts in Bengaluru, Karnataka, India.
