Privacy Policy

1. Who We Are

ZAVA Systems Co., Ltd. (operating as ZAVA, ZAVA Systems, and ZAVA Digital) is a software engineering company headquartered in Da Nang, Vietnam. This Privacy Policy explains what information we collect when you visit zavasystem.com or contact us, how we use it, and the rights you have over it.

2. Information We Collect

• Inquiry data — when you use our contact form, email, phone, or WhatsApp, we receive your name, email address, phone number, company, and the details of your project or inquiry.
• Technical data — standard server logs including IP address, browser type, referring page, and pages visited, used to operate and secure the site.
• Local preferences — your light/dark theme choice is stored locally in your browser (localStorage) and never transmitted to us.

3. How We Use Your Information

• Respond to inquiries and prepare technical proposals.
• Evaluate project feasibility and staffing for your engagement.
• Operate, secure, and improve the website.
• Meet legal, accounting, and contractual obligations.

4. Legal Bases (GDPR)

Where the GDPR applies, we rely on your consent for optional communications, contract performance when we engage with you, and our legitimate interest in operating the business and responding to inquiries.

5. Cookies & Local Storage

We do not set third-party advertising or tracking cookies. Our only browser storage is the theme preference saved via localStorage, which never leaves your device.

6. How We Share Information

We do not sell or rent your personal data. We share information only with service providers who help us operate (such as hosting and email providers) under appropriate confidentiality terms, and where required by law.

7. Data Retention

Inquiry records are retained for as long as needed to respond to you and to fulfil contractual, accounting, and legal obligations. Server logs are retained for a limited period for security purposes.

8. Your Rights

Depending on your location, you may have the right to access, rectify, delete, restrict, or port your personal data, and to object to processing. To exercise any of these rights, email us at hello@zavasystem.com.

9. Security

We protect your data with industry-standard measures including HTTPS encryption, access controls, and confidentiality agreements with all team members and subcontractors.

10. International Transfers

Your information may be processed in Vietnam and in the hosting regions used to operate the website. We apply appropriate safeguards for any international transfer.

11. Children

Our services are intended for businesses and individuals aged 16 and over. We do not knowingly collect data from children.
