Privacy Policy

Last Updated: June 24, 2026

1. Introduction

At FullStack AI (accessible via fullstackai.online), we take your privacy very seriously. This Privacy Policy describes how we collect, use, and share information when you purchase our course or use our offline-ready course player web application.

2. Information We Collect

We collect very limited personal data to enable your access and provide updates:

  • Purchase Information: Payments are securely processed via Gumroad. When you buy the course, we receive transaction confirmations from Gumroad including your name, email address, transaction ID, and the license key generated for your account. We do not collect or store your payment card details or billing credentials.
  • Local Application Storage: Our course player web application stores your progress, completed module checklists, user preferences (such as light/dark theme), and license status locally in your browser's Local Storage. This data never leaves your device and is not uploaded to our servers.

3. How We Use Your Information

We use the collected transaction details for the following purposes:

  • To verify your license key when unlocking the offline course player.
  • To email you free updates when tech stack modifications or curriculum improvements are published.
  • To provide customer support and troubleshoot access issues.

4. Cookies and Web Storage

We do not use tracking cookies or marketing pixels. The course player uses native HTML5 Web Storage (Local Storage) solely to save your local course checklist progression and settings offline.

5. Data Security

We implement standard security measures to protect your receipt details and license keys. Our site uses secure HTTPS encryption. All transaction details are processed and secured in compliance with Gumroad's safety protocols.

6. Third-Party Services

Our payment gateway provider is Gumroad. When purchasing, your data is processed according to Gumroad's Privacy Policy. The course player also loads dependencies from reliable Content Delivery Networks (CDNs) including Cloudflare (cdnjs) for font, markdown parsing, and code syntax highlighting assets.

7. Your Rights

You can request to delete your purchase record or request access to check your purchase history. Contact us at support@fullstackai.online and we will address your query immediately.

8. Updates to this Policy

We may update this Privacy Policy from time to time to reflect operational or regulatory changes. Any changes will be posted on this page with an updated date.
