Privacy Policy

Yuzora Privacy Policy Effective date: 11 November 2026

1. Who we are

Yuzora is a hosted service for testing drone software in simulation, run by Yuzora Labs in Taiwan ("we", "us"). Yuzora Labs is not yet a registered company. This policy covers yuzora.dev, the web app at app.yuzora.dev and the Yuzora command-line tool. Contact us at support@yuzora.dev.

2. What we collect

• Sign-in details: your email address, and your user ID and name from GitHub or Google if you sign in with them. We never ask for a password.
• If you are invited: while Yuzora is invite-only, the email address or company domain we invited and the date we added it. If you never sign up, we remove it when the invite list closes or when you ask us to.
• What you upload: your drone set-ups (parameters, scripts and missions) and your tests.
• What your runs produce: flight recordings, logs, verdicts, measurements, reports, replays and videos.
• Records of your use: your plan, your runs, your access keys, and error records when something fails.
• Agreement records: when legal acceptance is enabled, the terms version you accepted, the privacy notice shown to you and the time of acceptance.

We use only the cookies needed to keep you signed in. We use no analytics, advertising or tracking.

3. How we use it

We use your information to sign you in, run your tests and show you the results, manage your runs and plan, send you sign-in links and messages about the service, prevent abuse, fix problems, and meet legal obligations. We may use counts that do not identify you or your team to improve the service.

We do not sell your information, share your uploads or results with other customers, or use them to train AI models. We look at your uploads or results only when you ask for help, when we investigate a failure or misuse, or when the law requires it.

For users in the EU and the UK: we use your information because it is needed to provide the service you signed up for, for our legitimate interests in security and improving the service, and to meet legal obligations.

4. Who else handles it

• Amazon Web Services hosts the service and sends sign-in emails.
• GitHub and Google, if you sign in with them.
• Google Workspace holds the emails you send to support@yuzora.dev.

We share your information with anyone else only when the law requires it, or to protect the service or its users.

5. Where it is stored

We store application account data, uploads and test results with Amazon Web Services in Taiwan. We send sign-in emails through Amazon Web Services in Japan. GitHub, Google and Google Workspace may process sign-in and support information in other countries under their applicable terms and privacy policies. If you use Yuzora from another country, your application data is transferred to Taiwan.

6. How long we keep it

We keep your application account data, uploads and results until you delete them or your account. Account deletion ends access immediately and starts removal from live application systems. If removal fails, we retry it. Scheduled backups are configured to expire 30 days after creation; removal by the storage provider can take longer. Temporary copies made for maintenance are handled separately.

We also keep temporary sign-in records while you sign in, including if you do not finish creating an account. These records expire and are removed during routine cleanup.

We retain the account identifier and deletion time to prevent a backup restore from bringing back a deleted account. These records do not contain your email address. Error records are kept for about 30 days.

Deleting an account does not remove its invitation from the invite list or emails you sent to support. Ask support@yuzora.dev to remove those separately. Files you downloaded and records providers keep for their own service operations are outside application account deletion.

7. Security

We protect your information with encryption and access controls. No system is perfectly secure. If a breach affects your information, we will tell you as the law requires.

8. Your rights

You can see your runs and results in the web app, download your files with the command-line tool, and delete your account in the web app at any time. You can also ask us to access, correct, export or delete your information by writing to support@yuzora.dev. If you are in the EU or the UK, you may complain to your data protection authority.

9. Age

Yuzora is for people aged 18 and over.

10. Changes

If we change this policy in a way that matters to you, we will email you at least 30 days before the change takes effect.
