Terms of use

Last updated 29 October 2026.

By using Retrystorm you agree to these terms.

The service

Retrystorm is an educational site for learning system design. The lessons and the simulator are free. Some mock interview features need a paid pass, shown with its price and allowance before you buy.

Use it fairly

Don't try to break the site, scrape it at scale, resell its content, or use the mock interview features to generate unrelated text. We may limit or suspend accounts that do.

Your content

What you write in a mock interview stays yours. You allow us to store it and to send it to our model provider so the interviewer and review can work. You can ask for it to be deleted (see the privacy policy).

Passes and payments

A pass gives an allowance of mock interviews and full reviews for a period. Payments are handled by our payment provider. A pass is used up by use or by time, whichever comes first. If something went wrong with a purchase, contact us and we will sort it out.

No guarantee

The simulator is a teaching model, and the interviewer and reviews are written by an AI model that can be wrong. They are practice and feedback, not a prediction of how any real interview will go or a guarantee of any result. The site is provided as it is, without warranties, and to the extent the law allows we are not liable for losses from using it.

Changes

We may change the site or these terms. If a change matters, the date above changes with it.
