Terms of Service

Yuzora Terms of Service Effective date: 11 November 2026

1. Agreement

These terms are an agreement between you and the operator of Yuzora, trading as Yuzora Labs in Taiwan ("we", "us"). You agree to these terms by selecting the acceptance checkbox and continuing during sign-in. If you use Yuzora for an organisation, you confirm that you may accept these terms for it. You must be 18 or over.

2. What Yuzora is

Yuzora flies your drone software in simulation and reports the results. It is in early access and, for now, by invitation only: features, limits and prices may change.

3. Simulation is not certification

• Yuzora's results come from simulation, which uses simplified models. A real drone can behave differently.
• A PASSED result is not certification, approval or a guarantee that a drone is safe. A FAILED result does not prove that a real drone would fail.
• You remain responsible for testing your drone in the real world, for its safe operation, and for following the laws that apply to it.
• Do not present Yuzora's results as certification or as an endorsement by us.

4. Your account

Keep your access keys secret; you are responsible for what is done with your account. Do not create extra accounts to get more free runs.

5. Your content

You keep all rights to what you upload and to your results. You allow us to store, process and run your content only to provide Yuzora to you. This ends when you delete your content or your account, except for backup copies until they expire. You confirm that you have the right to upload your content.

6. Acceptable use

Do not use Yuzora for anything unlawful, including breaking export-control or sanctions laws. Do not try to get around limits, break out of the simulator, access another team's data, or disrupt the service.

7. Free runs and paid plans

The free allowance, the limits per team and how runs are counted are described at https://app.yuzora.dev/help/runs. Paid plans are offered by separate agreement. We will email you at least 30 days before we reduce the free allowance.

8. Availability

We make no promise of availability or speed. We may change or stop features.

9. Ending the agreement

You can delete your account at any time. We may suspend or close an account that breaks these terms or harms the service or other users, or when the law requires it.

10. No warranties and limits of liability

Yuzora is provided "as is". To the extent permitted by law, we disclaim warranties and liability for indirect losses. Subject to the exceptions below, our total liability to you is limited to the greater of the fees you paid us in the 12 months before the claim or US$100. Section 3 explains the limits of simulation results and your responsibility for real-world testing and operation.

These exclusions and limits do not apply to intentional misconduct, gross negligence, or any liability that cannot legally be excluded or limited. Nothing in these terms limits mandatory consumer rights, including rights under the laws of your own country.

11. Open-source software

Yuzora runs open-source software, including ArduPilot, PX4 and Gazebo, under their own licences. Yuzora is not affiliated with ArduPilot, PX4, Gazebo, GitHub or Google.

12. Law

These terms are governed by the laws of Taiwan. The Taiwan Taipei District Court is the court of first instance, unless your country's law gives you, as a consumer, the right to bring a claim at home.

13. Changes and contact

If we change these terms in a way that matters to you, we will email you at least 30 days before the change takes effect. Contact us at support@yuzora.dev.
