Privacy Policy

Last updated: June 9, 2025

At BiuBiuVPN, we prioritize the privacy of our users. This Privacy Policy details the data we gather, the ways we utilize it, and your rights concerning your information.

This Privacy Policy outlines how BiuBiuVPN collects, uses, and shares your personal information. BiuBiuVPN is operated by Super Tools Technology Co., Limited ("we", "us", or "our"), a Hong Kong-based company. We are dedicated to providing a secure and free online environment for users around the world.

We will not collect, process, store, or transfer your data without your consent. By submitting your personal data and accessing or using our Services, you confirm that you have read and understood this Privacy Policy and agree to its terms.

BiuBiuVPN only collects the minimum data necessary to enhance our VPN services. With this commitment, we guarantee:

BiuBiuVPN does not store your IP address or the server IP address you connect to.
BiuBiuVPN does not log your browsing history, data content, or DNS queries.
BiuBiuVPN will not sell, use, or disclose any data to third parties, including government entities, for any purpose.

User-provided information

1.Some features rely on Google Firebase. For more information about privacy, please see: https://firebase.google.com/support/privacAs a result, we collect the following information:

Your device ID, which is used for user authentication only.

2.Our VPN app operates as a no-log network, meaning we do not collect personal information unless under limited, specific exceptions. By default, we do not automatically gather any personal data from users.

When you launch the app to use our VPN services, the app assigns a unique identifier to your session. This identifier is linked only to your device’s identification code and is not associated with any other personal information. We use this identifier solely to verify your account and determine the service level you are entitled to before establishing your VPN connection.

If you contact us directly, we may collect additional information such as your name, email address, phone number, message contents, attachments, or any other details you choose to share. We may also receive a notification when you open an email from us.

If you choose to provide your email address, it may be used for the following purpose:

To communicate with you regarding your VPN services or respond to your inquiries.

We use your personal information only as described in this Privacy Policy. We do not sell your personal data to third parties without your explicit consent.

3.Service Information Related to Your VPN Usage

In compliance with applicable laws and to avoid conflicts with internet service providers, all data related to your online activity—such as browsing history, traffic destinations, data content, IP addresses, and DNS queries—is encrypted and immediately cleared once your VPN session ends. In other words, we do not collect or store information about the websites you visit, the data stored on or transmitted from your device, or the data transmitted through the VPN by any apps on your device.

More specifically, due to our minimal data collection policy and the absence of links to personal information, we do notpossess the following information:

We do not know which user accessed a particular website or service.
We do not know which user was connected to the VPN at any specific time.
We do not know the original IP address of a user’s device or the temporary IP address assigned during the VPN session.

If any third party attempts to compel us to release such data, we cannot comply—because that information simply does not exist.

What We Do Collect (for Service Performance and Support)

To fulfill our contractual obligations and deliver high-quality VPN service, we collect the following non-personally identifiable information related to your VPN usage:

3.1 App and Version Information
We collect data about which app and app version you are using. This helps our support team quickly diagnose and resolve technical issues.

3.2.Connection Information
We log basic information such as:

Whether a VPN connection was successful on a specific date (not the exact time),
The VPN server location you connected to (not your outgoing IP address),
Your country and ISP (but not your source IP address).

This limited data helps us provide efficient technical support, such as troubleshooting connection issues and offering country-specific advice.

3.3 Anonymous Network Diagnostics and Analytics
With your permission, we collect minimal anonymized data to optimize our network performance. This includes:

Diagnostic data on failed connection attempts,
Speed test results,
Crash reports (collected without any personally identifiable information).
Crash reports may be handled by third-party services depending on your platform. For iOS users, crash reporting can be disabled via system settings.

These analytics are fully anonymized—we do not track which user sent which data, and we do not store IP addresses.

Conclusion
We collect only the minimal necessary usage statistics to maintain and improve our service quality. Because thousands of users connect to the same VPN location at the same time, no individual behavior can be singled out or identified. Usage patterns are shared among thousands of users, making it impossible to trace any activity back to a specific person.

We have deliberately engineered our systems to avoid storing any sensitive data. As a result, we do not know how users utilize our service. Our firm commitment to user privacy means we retain no information regarding your online activity.

6.GDPR Compliance

We are committed to safeguarding user privacy on a global scale. Our approach emphasizes minimal data collection and empowering users to control their personal information. In compliance with the General Data Protection Regulation (GDPR) of the European Union (EU), we collect and process data from users in the EU in a specific manner, as outlined in this Privacy Policy, based on the following legal grounds:

Automatically collected information

Our app does not track your web browsing activity or collect location data from your mobile device. We offer a Split Tunneling feature (for Android), which you can choose to enable or disable. If you enable it, the app will need to access information from your device to establish a VPN tunnel. We do not store or download your app information. We utilize Firebase for crash analysis to review crash logs only.

We have obtained your consent.
We are legally obligated to do so.

However, please note that no method of internet transmission or electronic storage is 100% secure, and we cannot guarantee absolute security.
