Content & Privacy

While learning and working with different technologies, I have referred to trusted online resources, official documentation, technical articles, and other reliable sources. I have also created and maintained my own notes to understand concepts more clearly and make them easier to revise later. The platform also includes the complete AI Engineering notes, with source examples, diagrams, practical projects, and interview answers.

I’ve tried to explain these concepts in simple, easy-to-understand language, focusing on practical understanding rather than unnecessarily complicated explanations.

These resources represent my personal understanding and experience. They are intended to help you learn, revise, and prepare more effectively, but they should not be considered a replacement for official documentation or the original sources. I encourage you to explore official documentation and trusted resources whenever you want to dive deeper into a topic.

I’m sharing what I’ve learned because I know how difficult it can be to navigate through hundreds of resources, understand what actually matters, and prepare for interviews while continuing to grow as a developer.

If my notes, experiences, and the way I’ve organized these topics can help you understand something faster, prepare better, or find the right direction, then building this platform is worth it.

I’ll continue improving and expanding the platform as I learn, work with new technologies, and gain more professional experience.

Your Progress & Privacy

Reading, search, learning paths, and practice do not require an application account. When sign-in is available, an account lets you save bookmarks and lesson and question completion across devices.

We store the basic account profile supplied by your sign-in provider and the lessons and questions you choose to save or complete. Signed-in lesson visits record your most recent reading place. Finished practice sessions record question IDs and the number reviewed. Practice drafts remain temporary page state and are not sent to the server.

Sessions use HttpOnly cookies. Personal progress is associated with your account and is excluded from public caches. Use the same account on another device to access your saved progress. A provider can connect to an existing account only when both email addresses are verified and match. Passwords are stored as hashes. Short-lived verification and recovery codes are stored as keyed hashes and are invalidated after use.

Optional Usage Analytics

Usage analytics is disabled unless it is configured for the site and you enable it using the analytics control. The integration records public page views and content completion counts. The application does not include search queries, account identifiers, or practice drafts in its analytics events. You can disable it using the same control.

Code Playground & Privacy

Compiler runs send your source code and program input to Wandbox. We request execution without saving a public permalink. The provider may handle request data according to its own practices. Avoid submitting secrets or private project code.

LearnAndCode does not store playground source code, input, or results in its database. Drafts remain temporary page state. We store a hashed network identifier and short-window counters to limit repeated compiler requests. HTML/CSS previews stay in a restricted browser frame and do not use the hosted compiler.
