Privacy Policy

This English version is provided for convenience. If it differs from the Chinese version, the Chinese version prevails.

Effective September 24, 2026

This Privacy Policy explains what personal information kxbuild ("we", "us" or "our") processes when you use the KXBuild software, website and Dashboard (together, the "Services"), why we process it, who processes it for us, and how you can manage it.

Please pay particular attention to the content shown in bold, which covers how we process information such as device identifiers and network location, and how we transfer it across borders. By using the Services, you confirm that you have read and understood this Privacy Policy. It applies together with our Terms of Service.

1. Information we collect

• Account information. The email address or phone number and password you provide when you sign up. Passwords are stored only in an irreversibly encrypted form.
• Device information. Your development machine's hardware identifiers (sent only as irreversible hashes), computer name and OS version when you activate or verify a license, and your browser's identifier when you sign in to the Dashboard.
• Network information. Your IP address when you sign in or verify a license, and the approximate city derived from it.
• Transaction information. Records of plan purchases, referrals and credit redemptions. Payments are completed on the payment provider's platform, and we never handle your bank card or other payment details.
• Information you give us. The content and attachments of emails you send us.

We do not collect the following.

• Your source code, project files, build output or build logs. Compiling, signing and debugging all happen on your own computer.
• Feature usage data or crash reports from the software.
• Precise location, contacts, photos or other information unrelated to the Services.

2. When the software connects to the internet

• License verification. Operations that require a license, such as builds, check it online and send the device information listed in section 1.
• Update checks and component downloads. These requests ask only for version information and installers, and carry no account or device information.
• Third-party download sources. Some tools, and the dependencies your project declares, are downloaded from their official sources. Those sites receive your IP address, as with any ordinary web request.
• Debugging on an iPhone and signing apps. KXBuild contacts Apple's servers as part of the standard iOS development workflow and sends the device information required. This information goes directly to Apple and does not pass through our servers.

3. How we use information

• To provide the Services, including creating and managing accounts, activating and verifying licenses, processing orders, and issuing credits and rewards.
• To keep the Services secure, including detecting unusual sign-ins, bulk registrations, abuse of trials and credits, and license code sharing.
• To send service notices, such as email verification codes, order confirmations and important policy changes.
• To provide customer support, including answering your questions and investigating issues you report.
• To comply with the law, including meeting our legal obligations and responding to lawful requests from competent authorities.

If we want to use information for any purpose not described in this Privacy Policy, we will ask for your consent first.

4. Cookies and similar technologies

The website and Dashboard use cookies and browser local storage in the following categories.

• Essential. Keep you signed in, protect your account and complete payments. Some features stop working if you turn these off.
• Preferences. Remember the language and interface settings you choose.
• Analytics. Help us understand how the website is visited.

We do not use advertising cookies. You can clear or block cookies in your browser settings.

5. How we share information

We do not sell your personal information. We share only the information that is necessary with third parties, and only in the following cases.

5.1 Service providers. These providers may process information only on our instructions and only to provide the Services.

• Cloud providers, for servers, databases and storage.
• Email providers, for sending verification codes and notifications.

5.2 Payment providers. When you pay, your payment information is collected directly by the payment provider you choose and handled under its privacy policy.

5.3 Legal requirements. To the extent necessary, when required by law, legal proceedings or competent authorities, or to protect the safety and property of you, us or the public.

5.4 Business transfers. In a merger, acquisition or asset transfer, personal information may be transferred as part of the transaction. We will notify you and require the recipient to continue to follow this Privacy Policy.

5.5 Any other case with your consent.

6. Where we store information and international transfers

Your personal information is stored on servers in mainland China. If you use the Services from outside mainland China, your information is transferred to mainland China for processing.

We apply the safeguards required by applicable law to these international transfers.

7. How long we keep information

• Account and device information is kept for as long as your account exists. Records of devices that have been inactive for a long time are purged periodically.
• Orders and transaction records are kept for the period required by law.

When the retention period ends or you delete your account, we delete or anonymize your personal information, unless the law requires us to keep it.

8. Security

We use reasonable technical and organizational measures to protect your information, including encryption in transit, encrypted password storage and access controls.

No system on the internet is perfectly secure. If a security incident such as a personal data breach occurs, we will take remedial action immediately and notify you and the relevant regulators as the law requires.

9. Your rights

You have the following rights over your personal information.

• Access and copy. Find out what information we hold about you and get a copy of it.
• Correction. Change your password in the Dashboard, or ask us to correct inaccurate information.
• Deletion. Ask us to delete your information in the circumstances provided by law.
• Account deletion. Deleting your account permanently cancels the plans, licenses and credits in it, and they cannot be restored.
• Withdraw consent, object to or restrict processing. Withdrawing consent does not affect processing carried out before the withdrawal.
• Explanation. Learn the rules we follow when processing your information.

Anything you can do in the Dashboard, you can do there directly. For any other request, email admin@kxbuild.net from your registered email address. To protect your account, we may need to verify your identity first. We will reply within 15 business days.

If you are not satisfied with our reply, you can file a complaint with the personal information protection authority where you live.

10. Additional information for specific regions

10.1 European Economic Area and United Kingdom. Our legal bases for processing your personal information are performing our contract with you (providing the Services and processing orders), our legitimate interests (keeping the Services secure and preventing abuse), complying with legal obligations, and your consent. You also have the right to data portability and the right to lodge a complaint with your local data protection authority.

10.2 California, United States. We do not sell your personal information or share it for cross-context behavioral advertising. You have the right to know, delete and correct your personal information, and you will not be discriminated against for exercising these rights.

11. Children

The Services are intended for developers and are not directed to children under 14 (under 16 in the European Economic Area and the United Kingdom). If we learn that we have collected a child's personal information without a parent's or guardian's consent, we will delete it as soon as possible.

12. Changes to this Privacy Policy

We may update this Privacy Policy. We will post the updated version on this page and update the effective date. If the types of information we collect, the purposes we use it for or the parties we share it with change materially, we will notify you in advance through the website, the Dashboard or email, and ask for your consent again where required.
