Zanboxx

Terms of service

Last updated 31 October 2026

In short: Zanboxx is a testing tool. It never moves real money. Use only the test card numbers we publish, keep your API key secret, and don't misuse the service.

1. Who we are and what these terms cover

Zanboxx is operated by [operator name not set], [operator address not set] ("we", "us"). You can reach us at [contact email not set]. These terms apply to the website, the API and anything else we offer under the Zanboxx name (the "Service"). By creating an API key or using the Service you agree to these terms and to our Privacy policy. If you use the Service for a company, you confirm you may bind that company.

2. What the Service is

Zanboxx simulates a payment gateway so that developers can test checkout code. All payments, cards, refunds, notifications and results are simulated. No real payment is ever authorised, captured or refunded, and no money moves. Zanboxx is an independent project. It is not a bank, a payment institution or a payment service provider, and it is not affiliated with or endorsed by any payment provider or card scheme.

3. Who may use it

The Service is meant for software developers and businesses, and for professional use. You must be at least 18 years old and able to enter a binding contract.

4. Your account and API key

5. Acceptable use

You agree not to:

We may limit, suspend or close accounts that break these rules or put the Service at risk, with or without notice where we think it is necessary to protect the Service or other people.

6. Plans and limits

The Free plan is free and has monthly and per-minute limits that are shown on the website and returned by the API. The Pro plan has higher limits and costs the price shown at checkout. Limits and features may change. If we reduce what a paid plan includes, we will tell you before the change reaches your next billing period.

7. Paid plans, billing and cancellation

8. Availability and changes

We try to keep the Service running, but we do not promise it will be uninterrupted, error-free or always available. There is no service-level agreement. Test data may be lost, for example during maintenance or an outage, so do not treat it as a record you must keep. We may change, add or remove features, including the simulated behaviour and the test cards, and we may stop offering the Service. If we stop offering a paid plan, we will end billing and refund the part of the current period you can no longer use.

9. Your data

You own what you send to the Service. You give us permission to store and process it only as needed to run the Service for you. How we handle personal data is described in the Privacy policy. You can delete your account and its data yourself at any time with the "Delete account" option on the website or the DELETE /v1/account API call.

10. Our rights

We keep all rights in the Service, its software and its design. You get a personal, non-exclusive, non-transferable right to use the Service under these terms. The name Zanboxx and the website are ours. Feedback you send us may be used to improve the Service without obligation to you.

11. No warranty

The Service is provided "as is" and "as available". Because it is a simulation, it may behave differently from a real payment gateway, bank or card scheme. Passing tests against Zanboxx does not mean that your integration will work with a real provider, so always test with your real provider before going live. To the extent the law allows, we give no warranties of any kind, including merchantability, fitness for a particular purpose and non-infringement.

12. Liability

To the extent the law allows, we are not liable for indirect or consequential loss, lost profit, lost revenue, lost data or business interruption arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the event that caused the claim (or EUR 100 if you only used the Free plan). Nothing in these terms limits or excludes liability that cannot be limited or excluded by law, such as liability for intent, gross negligence, injury to life, body or health, or other liability that mandatory law does not allow us to exclude.

13. Ending the agreement

You can stop using the Service and delete your account whenever you like. We may suspend or end your access if you break these terms, if the law requires it, or if we stop offering the Service. Sections that by their nature should continue (for example on liability and governing law) continue after the agreement ends.

14. Changes to these terms

We may update these terms. If a change is significant, we will show a notice on the website before it takes effect. If you keep using the Service after the new terms apply, you accept them. If you do not agree, stop using the Service and delete your account.

15. Governing law and contact

These terms are governed by the law of Germany, without its conflict-of-law rules, and subject to any mandatory consumer or business protections that apply to you under your local law. Courts at the place where we are established have jurisdiction, unless mandatory law gives you the right to go to another court. Questions, complaints or notices: [contact email not set].
