Privacy Policy.

Who We Are & Why This Matters

BuildStak ("we," "our," or "us") is an online education platform offering construction training courses in English, Spanish, and Portuguese. We are committed to protecting your personal information and being transparent about how we use it.

This Privacy Policy explains what data we collect, why we collect it, how we use it, and what rights you have. By using our website or purchasing any course, you agree to the practices described here.

Information We Collect

We collect information in two ways — information you give us directly, and information collected automatically when you use our platform.

Information you provide:

• Name and email address when you create an account or purchase a course
• Billing information (processed securely by our payment provider — we never store full card details)
• Language preference and course progress
• Any messages or feedback you send us

Information collected automatically:

• Device type, browser, and operating system
• Pages visited and time spent on our platform
• IP address and general geographic location (country/state level)
• Cookies and similar tracking technologies (see Section 05)

How We Use Your Information

We use your information solely to provide and improve our services. Specifically:

• To create and manage your account and deliver course access
• To process payments and send purchase confirmations
• To issue your certificates of completion
• To send important updates about your courses or our platform
• To send occasional promotional emails about new courses or offers — you can opt out at any time
• To analyze usage patterns and improve our platform experience
• To comply with legal obligations

Sharing Your Information

We do not sell, rent, or trade your personal information to third parties. We may share limited data only in the following circumstances:

• Service providers: Trusted third parties who help us operate our platform (e.g., payment processors, email delivery, hosting). They are bound by strict data protection agreements.
• Legal requirements: If required by law, court order, or government authority.
• Business transfers: In the event of a merger or acquisition, your data may be transferred — you will be notified.

Data Retention

We retain your personal data for as long as your account is active or as needed to provide services. If you delete your account, we will delete or anonymize your personal information within 30 days, except where we are required to retain it for legal or financial compliance purposes.

Course completion records and certificates may be retained for a longer period to support re-issuance requests.

Cookies

We use cookies — small text files stored on your device — to keep you logged in, remember your preferences, and understand how our platform is used. We use:

• Essential cookies: Required for the platform to function (login sessions, cart, language).
• Analytics cookies: Help us understand usage patterns (e.g., Google Analytics). These are anonymized.
• Marketing cookies: Used to measure the effectiveness of our advertising. You may opt out.

You can control cookies through your browser settings. Disabling essential cookies may affect platform functionality.

Your Rights

Depending on your location, you may have the following rights regarding your personal data:

• Access: Request a copy of the personal data we hold about you.
• Correction: Request that we correct inaccurate or incomplete data.
• Deletion: Request that we delete your data ("right to be forgotten").
• Portability: Request your data in a structured, machine-readable format.
• Opt-out: Unsubscribe from marketing emails at any time via the link in any email we send.
• Objection: Object to certain types of data processing.

To exercise any of these rights, contact us at the address below. We will respond within 15 business days.

Security

We implement industry-standard security measures to protect your data — including SSL encryption, secure payment processing, and access controls. While we do everything reasonably possible to protect your information, no method of transmission over the internet is 100% secure.

We encourage you to use a strong, unique password for your BuildStak account and to notify us immediately if you suspect unauthorized access.

Children's Privacy

BuildStak courses are intended for professional adults in the construction industry. Our platform is not directed at children under 13 years of age, and we do not knowingly collect personal data from minors. If you believe a minor has provided us with personal information, please contact us and we will delete it promptly.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. When we make material changes, we will notify you by email or by posting a notice on our platform at least 7 days before the changes take effect.

Your continued use of BuildStak after any changes constitutes acceptance of the updated policy. We recommend reviewing this page periodically.
