Privacy Policy

Last updated: June 23, 2026

This Privacy Policy explains how TechTack LLC ("TechTack", "we", "us") collects, uses, and safeguards your information when you visit https://www.techtack.com.vn or contact us. By using our website, you agree to the practices described here.

1. Information We Collect

  • Information you provide. When you submit our contact or consultation form, we collect your name, email address, and the content of your message.
  • Usage data. We automatically collect anonymized analytics such as pages visited, referrer, approximate location, device, and browser, via Vercel Analytics, Vercel Speed Insights, and Google Analytics 4 (with IP anonymization enabled).
  • Cookies and similar technologies. Some third-party widgets (e.g. the Trustpilot review widget and its associated Hotjar analytics) set cookies. See "Cookies" below.

2. How We Use Your Information

  • To respond to your enquiries and provide consultations.
  • To operate, maintain, and improve our website and services.
  • To analyze aggregate traffic and usage trends.
  • To meet legal and regulatory obligations.

3. Legal Bases for Processing

Where the GDPR applies, we process personal data on the basis of your consent (analytics cookies), our legitimate interests (operating and improving the site), and to take steps at your request before entering into a contract (responding to enquiries).

4. Sharing and Disclosure

We do not sell your personal data. We share it only with service providers that help us operate the site, including Vercel (hosting and analytics), Supabase (database and storage), Resend (transactional email delivery), Google (analytics), and Trustpilot (reviews). Each processes data under its own terms. We may also disclose information where required by law.

5. Cookies

Essential cookies keep the site functioning. Analytics and third-party widgets may set additional cookies. You can control or block cookies through your browser settings; disabling them may affect some features.

6. Data Retention

We retain contact-form submissions for as long as needed to respond to and document your enquiry, and analytics data for the period set by the respective provider. We delete or anonymize data when it is no longer required.

7. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, delete, or restrict processing of your personal data, and to object to processing or request portability. To exercise these rights, contact us at contact@techtack.com.vn.

8. Data Security

We apply reasonable technical and organizational measures to protect your data. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

9. International Transfers

We are based in Vietnam and use service providers that may process data in other countries. Where required, we rely on appropriate safeguards for international transfers.

10. Children's Privacy

Our website is not directed to children under 16, and we do not knowingly collect their personal data.

11. Changes to This Policy

We may update this Policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
