SwitchProof

Terms of Service

Last updated 27 September 2026

These terms apply when you create a SwitchProof account, install SwitchProof for Windows or buy a plan. Please read them. If you use SwitchProof for your employer, you accept them on its behalf.

1. Who we are

SwitchProof is provided by Najeebullah Usmani ("we", "us"). You can reach us at najusmani@gmail.com.

2. What SwitchProof is

SwitchProof is a testing tool for card switches that use ISO 8583 messages. It has two parts:

The console runs in your browser and talks directly to the agent on your PC.

3. Your account

4. Plans and your licence

SwitchProof has a Free plan and paid plans (Team and Enterprise), described on the Pricing page. While your plan is active, we give you a personal, non-exclusive, non-transferable licence to use SwitchProof for testing in your organisation, within the limits of that plan.

5. Buying a plan

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

6. Using SwitchProof responsibly

SwitchProof sends real messages to real systems. You agree that:

7. Your data

What you test with (switch addresses, messages, card and account numbers, results, reports and database credentials) is stored by the agent on your PC. It is not sent to us, and you are responsible for keeping backups. Our Privacy Policy explains the account and payment information we do hold.

8. Other companies' software

9. Updates and availability

We improve SwitchProof over time and may change or remove features. Sometimes the website needs a newer agent; it will then ask you to install the update. We aim to keep the website available but can't promise it will always be, for example during maintenance or problems at our hosting providers.

10. No warranty

SwitchProof is provided "as is". It is a testing aid: its results depend on how you set it up and on the systems you test, and it does not certify that a switch or bank system is correct or compliant. Check the results before you rely on them, for example for a sign-off. To the extent the law allows, we give no other warranties, express or implied.

11. Limit of liability

To the extent the law allows, we are not liable for indirect or consequential losses, lost profits or revenue, lost data, or disruption to systems you test. Our total liability for any claim about SwitchProof is limited to what you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law.

12. Ending your use

You can stop using SwitchProof at any time and ask us to delete your account by email. We may suspend or close an account that breaks these terms, after telling you where we reasonably can. When your account ends, your licence ends too.

13. Changes to these terms

If we change these terms, we will post the new version here with a new date. If a change significantly affects a paid plan, we will email you before it applies. Using SwitchProof after a change means you accept it.

14. Law and disputes

These terms are governed by the laws of the Republic of Türkiye, and the courts of Türkiye have jurisdiction. If you are a consumer, you keep any protections that the law of your own country gives you and that cannot be excluded.
