This Privacy Policy explains how TUBE PREAMP, an independent personal brand based in Shenzhen, China (“we”, “us”, or “our”), handles information collected through zsl40.top.
Information we collect
When you join our early-access list, we collect the email address you submit and related subscription records, such as the time of signup and consent status. Our hosting, security, analytics, and form tools may also process technical information such as IP address, browser type, device information, referral URL, cookies, and site activity.
How we use information
- Send product-development, prototype, early-access, and launch updates you requested.
- Operate, secure, troubleshoot, and improve the website.
- Measure aggregate website performance and prevent abuse or spam.
- Comply with applicable legal obligations and respond to lawful requests.
Legal basis and your choice
Where consent is required, we rely on your consent to send product-update emails. You may withdraw consent at any time by using the unsubscribe method in an email or contacting us. Withdrawal does not affect processing that occurred before withdrawal. We may also process limited technical data where necessary for website security, operation, and our legitimate interests, subject to applicable law.
Service providers and international transfers
We may use service providers for hosting, website administration, security, analytics, forms, and email delivery, including Hostinger, WordPress-related services, and Google services. These providers may process data in countries outside your own. Where required, we seek to use appropriate contractual or legal safeguards. We do not sell your email address.
Cookies and analytics
The website may use essential cookies for security and administration and analytics technologies to understand site performance. You can limit cookies through your browser settings, although some site functions may be affected.
Retention
We retain subscription information while you remain subscribed and for a limited period afterward where reasonably necessary to document consent, honor opt-out requests, resolve disputes, maintain security, or comply with law. We delete or anonymize information when it is no longer needed.
Your rights
Depending on your location, you may have rights to request access, correction, deletion, restriction, portability, or objection, and to withdraw consent or complain to a competent data-protection authority. To make a request, contact us using the address below. We may need to verify your identity before completing a request.
Email communications
Our marketing or product-update emails will identify the sender and provide a clear way to unsubscribe. We will process valid opt-out requests as required by applicable law.
Children
This website and early-access program are intended for adults and are not directed to children. If you believe a child has submitted personal information, please contact us so we can review and remove it where appropriate.
