Terms of Service
Last updated 31 July 2026
These terms govern your use of the GSTIN Suite apps and this website, published by Mad Over Technology. Installing or using an app means you accept them.
Please read section 3. These apps help you calculate and check things quickly. They are not a substitute for professional advice, and they cannot confirm that a GST registration is genuine or active.
1. Licence
We grant you a personal, non-exclusive, non-transferable licence to use the apps on devices you own or control. You may not resell, redistribute, reverse-engineer or attempt to extract the source of the apps, except to the extent that applicable law expressly permits it.
2. Not affiliated with the government
Mad Over Technology is an independent developer. The apps are not affiliated with, endorsed by, or connected to the Government of India, the GST Council, the Central Board of Indirect Taxes and Customs (CBIC), or the Goods and Services Tax Network (GSTN). They cannot file returns, pay tax, or transact with the GST portal on your behalf.
3. Accuracy, and what these apps cannot do
We take accuracy seriously. The calculation engine is tested against the rates notified by the GST Council, including the changes effective 22 September 2025. Even so:
- Rates change. Applicable rates and classifications are amended by notification. Confirm the current rate for your goods or services before relying on a figure for filing.
- A GSTIN check is a structural check. Verifying a GST number offline confirms that it is correctly formed: the state code, the embedded PAN, and the check digit. It cannot confirm that the number was ever issued, that it belongs to the business claiming it, or that the registration is currently active. Only the official GST portal can tell you that.
- Classification is your responsibility. Choosing the right HSN or SAC code for a product or service is a judgement call with legal consequences. Any lookup we provide is a convenience, not advice.
The apps do not provide tax, accounting, legal or financial advice. For anything with consequences, consult a qualified Chartered Accountant or tax practitioner.
4. Your data and your backups
Your data lives on your device, as described in our privacy policy. That means we cannot restore it. If you lose your device, uninstall an app, or clear its storage, the data is gone. Where an app offers an export, use it to keep your own backups of anything you would be sorry to lose.
5. Advertising and purchases
Free versions display a single banner advertisement. We do not control the content of individual ads, which are selected by Google AdMob; you can report an inappropriate ad to us and we will pass it on.
Ad removal is a one-time purchase, not a subscription, and will not auto-renew or recur. It applies to the app you bought it in, on the store account used to buy it. Refunds are governed by the policies of Google Play or the Apple App Store, which handle the transaction; we will help you with a refund request where we can.
6. Liability
The apps are provided “as is”. To the maximum extent permitted by law, we exclude implied warranties and are not liable for indirect or consequential loss, including any tax, interest or penalty arising from reliance on a figure produced by an app. Nothing in these terms limits liability that cannot lawfully be limited. Where liability cannot be excluded, it is limited to the amount you paid us for the app, if any.
7. Changes
We may update these terms as the apps change. The current version always lives at this URL, with the date shown above. Continuing to use an app after a change means you accept the revised terms.
8. Governing law
These terms are governed by the laws of India, and the courts at Bengaluru, Karnataka have exclusive jurisdiction, without prejudice to any mandatory consumer protections available to you where you live.
