Terms of Service

Last updated 25 September 2026

These terms apply to your use of λ master (the "service"), run by Lambda Master("we", "us"). By using the service you agree to them. If you don't agree, please don't use it.

The service

λ master offers practice quizzes, explanations and topic guides for software engineering interviews. You don't need an account. We may add, change or remove features, and the service may sometimes be unavailable.

Price

The service is currently free. We won't charge you without telling you first. Any paid feature will come with its own pricing, cancellation and refund terms, shown to you before you pay.

Acceptable use

You agree not to:

  • scrape, copy or republish the question bank or guides in bulk;
  • send automated traffic that overloads the service or gets around its rate limits;
  • try to access admin areas or other systems you aren't authorised to use;
  • submit reports or feedback that are unlawful, abusive, or contain someone else's personal data;
  • use the service in a way that breaks any law.

We may block access for anyone who breaks these rules.

Our content

The questions, explanations, guides, design and logo belong to us or our licensors. You may use them for your own personal, non-commercial study. Any other use needs our written permission.

Your feedback

If you report a question or send feedback, you let us use it freely to improve the service, without owing you anything for it.

Learning purposes only

We work to keep the content accurate, but it may contain mistakes or be out of date. It is practice material, not professional advice, and we don't promise any result in an interview or job search. If you spot an error, please report the question.

Warranties and liability

The service is provided "as is" and "as available", without warranties of any kind, to the extent the law allows. To the extent the law allows, we are not liable for any indirect or consequential loss, or for any loss arising from your use of, or inability to use, a free service.

Nothing in these terms limits liability that cannot be limited by law, such as liability for death or personal injury caused by negligence, or for fraud. If you are a consumer, nothing here affects your statutory rights.

Privacy

Our Privacy Policy explains what data we collect and how you can control analytics.

Changes to these terms

We may update these terms. We will change the date above when we do, and for significant changes we will give notice on the site. If you keep using the service after a change, the new terms apply.
