4. Content and ownership

- Problems link to other websites (LeetCode, GeeksforGeeks and others) and videos to YouTube. Those belong to their owners. We are not affiliated with them, and their own terms apply.

7. Liability
To the extent the law allows, we are not responsible for losses that come from using the site, for example lost progress or missed opportunities, except where the law does not allow us to exclude it. Nothing here limits any right you have under Indian law.

We may update these terms. For an important change we will update the date and tell you by email. Using the site after a change means you accept it.
9. Governing law
Indian law applies. Disputes go to the courts of Delhi, India.
