This Privacy Policy explains how system design Roadmap (systemdrd.com) collects, uses, and protects personal data when you learn system design, AI engineering, and hands-on distributed systems on our Platform.

Last updated: 2026-07-29

1. Who We Are

system design Roadmap (“we”, “us”) operates an online learning platform for software engineers at systemdrd.com and related domains. We offer courses, lessons, playgrounds, e-books, newsletters, forums, and subscription-based access to premium materials.

For privacy requests, contact us via the Contact page or email [email protected].

2. Scope

This Policy applies to visitors, free users, trial users, paid subscribers, and team/institutional learners who use the Platform website, dashboards, support chat, and related services.

3. Information We Collect

3.1 Account & profile data

  • Name, email address, username, and password (stored securely / hashed)
  • Optional profile details you provide (for example GitHub username for repository access)
  • Authentication events (including passwordless login codes or Google sign-in where enabled)

3.2 Learning & product data

  • Course enrollments, lesson progress, completion timestamps, and learning streaks
  • Dashboard activity, playground usage, and workflow practice interactions
  • Support chat messages and forum posts you submit
  • Newsletter subscription preferences and notification settings

3.3 Payment & billing data

  • Plan selection, subscription status, invoices, and transaction references
  • Payment card and bank details are handled by processors such as Stripe and/or PayU — we do not store full card PANs on our servers
  • Country or region signals used for pricing and payment routing (for example India plans)

3.4 Technical & analytics data

  • IP address, browser/device type, approximate location, referrer, and pages viewed
  • Session and event analytics used to improve curriculum, conversion, and reliability
  • Security logs needed to detect abuse, fraud, and unauthorized access

3.5 AI feature data

  • Prompts and context you submit to AI study helpers, plus generated responses stored as needed to deliver the feature

4. How We Use Your Information

We use personal data to:

  • Create and secure your account and deliver course, lesson, and playground access
  • Process subscriptions, trials, renewals, refunds, and invoices
  • Grant and revoke private GitHub repository access when your plan includes it
  • Send transactional email (welcome, billing, password resets, drip onboarding)
  • Provide optional marketing newsletters — you can unsubscribe at any time
  • Personalize learning progress, streaks, badges, and recommendations
  • Operate AI-assisted explanations and content helpers
  • Analyze product usage to improve system design curricula and Platform performance
  • Prevent fraud, enforce Terms of Service, and comply with legal obligations

5. Legal Bases (Where Applicable)

Depending on your location, we rely on one or more of: performance of a contract (providing the learning service you request), legitimate interests (security, product improvement, non-intrusive analytics), consent (optional marketing or certain cookies), and legal obligation (tax/accounting records).

6. Cookies & Similar Technologies

We use cookies and similar technologies to keep you signed in, remember preferences (including theme/country selectors where present), measure learning and marketing performance, and protect the Platform. You can control cookies through your browser; disabling essential cookies may break login or checkout.

7. Sharing & Processors

We do not sell your personal information. We share data only with service providers needed to run system design Roadmap, such as:

  • Payment processors — Stripe, PayU, and related billing portals
  • Email delivery — transactional and newsletter providers (for example Brevo API or SMTP)
  • Hosting & infrastructure — servers, CDN, and security tooling
  • AI providers — when you use AI features that call third-party models
  • Analytics — first-party and approved analytics used for product insights
  • GitHub — when granting repository access tied to your account

We may disclose information if required by law, to protect learners and the Platform, or in connection with a business transfer (merger or asset sale), subject to appropriate safeguards.

8. International Transfers

system design Roadmap serves a global engineering audience. Your data may be processed in countries other than your own. Where required, we use appropriate safeguards with processors.

9. Retention

We retain account and learning records while your account is active and for a reasonable period afterward for security, support, and legal/accounting needs. You may request deletion of your account data subject to lawful retention exceptions (for example paid invoice history).

10. Your Rights & Choices

Depending on your region, you may have rights to access, correct, delete, or export personal data, or to object to certain processing. You can:

  • Update profile details from your account settings where available
  • Manage notification / newsletter preferences
  • Cancel subscriptions through the billing portal or support
  • Request privacy help via Contact or [email protected]

11. Children’s Privacy

The Platform is intended for adults and professional learners. We do not knowingly collect personal data from children under 16 (or the minimum age required in your jurisdiction). If you believe a child has registered, contact us and we will take appropriate action.

12. Security

We apply administrative and technical measures appropriate to an online learning product (access controls, HTTPS, hashed credentials, payment tokenization via processors). No online service is perfectly secure; please use a strong unique password and protect your devices.

13. Third-Party Links

Lessons and marketing pages may link to external documentation, GitHub, Substack, or vendor sites. Their privacy practices are their own; review their policies before sharing data with them.

14. Changes to This Policy

We may update this Privacy Policy as features, processors, or laws change. We will revise the “Last updated” date and, for material changes, provide additional notice where appropriate.
