Disclaimer

Last updated: 13 October 2026

The information on Codevra is published in good faith for general educational purposes. By using the site, you accept the points set out below. This disclaimer should be read together with our terms of use.

Educational purpose

Codevra teaches programming concepts, languages and tools. Lessons, examples, exercises, quizzes and projects are designed to help you learn, not to serve as professional, legal, financial or security advice for a specific situation. If you are building software that handles money, health data, personal information or critical systems, seek advice from a qualified professional and follow the standards that apply to your industry.

Accuracy of content

We test our code examples and review lessons carefully, and we correct mistakes as soon as we find them. Even so, programming languages, frameworks, browsers and tools change regularly, and a lesson that was accurate when written may become outdated. We make no guarantee that every page is complete, current or without errors.

If you spot something that looks wrong, please tell us. Reports from learners are one of the main ways we keep lessons accurate.

Code examples

Code examples are written to explain one idea clearly. To keep them short and readable, they often leave out things a production application needs, such as full input validation, error handling, security hardening, accessibility testing, logging and performance tuning.

Before you use any code from Codevra in a real project:

• read it and make sure you understand what each line does;
• test it in your own environment, with your own data;
• check it against the official documentation for the version you use;
• review it for security issues, especially code that handles user input, files, databases or passwords.

You use code from this site at your own risk. Codevra is not responsible for any damage, data loss, downtime or security incident that results from using it.

Running code in your browser

Lessons and the code playground run HTML, CSS and JavaScript inside a sandboxed frame in your browser. Code you write runs on your own device. Avoid running code you don't understand, and never paste code from untrusted sources that asks for passwords, keys or other private information.

Examples for other languages

Examples for languages such as Python, Java, C++, C#, Kotlin, Swift, PHP, SQL and MongoDB show the expected output next to the code. That output comes from running the example with the version stated in the lesson. Results can differ slightly on other versions, operating systems or configurations.

No guarantee of results

Learning to program takes practice, and everyone progresses at a different speed. Time estimates on Codevra, such as how long a course or learning path takes, are general guides only. Completing lessons, paths or projects does not guarantee a job, a qualification, a pass in an exam or interview, or any particular income. Codevra does not award formal qualifications.

External links and services

Some pages link to other websites, such as official documentation, and some examples load data from public services. We include these links because we believe they are useful, but we don't control those websites and aren't responsible for their content, accuracy, availability or privacy practices. A link does not mean we endorse the site or its owner.

Trademarks

Names and logos of programming languages, frameworks, platforms and tools, including HTML5, CSS, JavaScript, Python, Java, Kotlin, Swift, C#, C++, PHP, Node.js, MySQL, PostgreSQL, MongoDB, Git and GitHub, are trademarks or registered trademarks of their respective owners. They are used on Codevra only to identify the technology being taught. Codevra is an independent learning site and is not affiliated with, sponsored by or endorsed by any of these owners.

Opinions

Where a lesson recommends a tool, style or approach, it reflects our view of good practice for beginners. Experienced developers sometimes make different choices for good reasons, and you are welcome to do the same.

Limitation of liability

To the fullest extent permitted by law, Codevra and the people who create its content will not be liable for any loss or damage of any kind arising from the use of, or reliance on, information or code on this site. Some jurisdictions don't allow certain limitations, so parts of this section may not apply to you.

Changes to this disclaimer

We may update this disclaimer as the site grows. The date at the top of the page shows when it last changed.
