Privacy Policy

Last updated: September 14, 2026

DataCodingHub ("we", "us", "our") operates the website datacodinghub.com and its practice platform (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices you have.

1. Information We Collect

When you create an account or use the Service, we collect:

  • Account information — your name, email address, and profile picture, provided either directly or via a third-party sign-in provider (e.g. Google).
  • Usage data — the practice questions you attempt, code you submit, pass/fail results, and progress history.
  • Technical data — IP address, browser type, and device information, collected automatically for security and analytics purposes.
  • Payment information — if you subscribe to a paid plan, billing details are collected and processed by our payment processor; we do not store full card numbers on our servers.

2. How We Use Your Information

  • To provide, maintain, and improve the Service
  • To authenticate your account and keep it secure
  • To track your progress and save your submitted code
  • To send account-related emails (e.g. password resets, billing receipts)
  • To send product updates or newsletters, only if you opt in
  • To respond to support requests submitted via our contact form

3. Sign in with Google

If you choose to sign in with Google, we receive your name, email address, and profile picture from Google as permitted by your consent on Google's sign-in screen. We use this solely to create and manage your DataCodingHub account. We do not post on your behalf or access any other Google account data.

4. Third-Party Services

We rely on the following third parties to operate the Service:

  • Supabase — authentication and database hosting
  • Google Cloud — backend code execution infrastructure
  • Vercel — frontend hosting
  • Payment processing for premium subscriptions (when enabled)

Each of these providers processes data under their own privacy policies and only to the extent necessary to provide their service to us.

5. Cookies

We use essential cookies to keep you signed in and remember your preferences. We do not use third-party advertising cookies.

6. Data Sharing & Disclosure

We do not sell your personal information. We only share data with the service providers listed above (Section 4) to the extent needed to operate DataCodingHub, or when required to comply with a legal obligation, court order, or valid governmental request.

7. Security of Your Information

We take reasonable technical and organizational measures to protect your data, including encrypted connections (HTTPS/TLS), password hashing, and access controls on our database. Payment details are handled entirely by our payment processor and are never stored on our own servers. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.

8. Data Retention

We retain your account data for as long as your account is active. You may request deletion of your account and associated data at any time by contacting us.

9. Your Rights

You may access, correct, or delete your personal data, or withdraw consent for optional communications, at any time by emailing us at support@datacodinghub.com or through your account settings.

10. Children's Privacy

The Service is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

11. Changes to This Policy

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