Terms of Service

Who you are contracting with

Codejump is operated by Atlas Code LLC, a limited liability company formed in Wyoming, United States, with its mailing address at 1021 E Lincolnway, Suite 10720, Cheyenne, WY 82001, United States. In these terms, “we”, “us” and “Codejump” mean Atlas Code LLC, and your agreement is with that company.

Using Codejump

By creating an account you agree to these terms. You need to be able to enter into a contract where you live; if you are using Codejump on behalf of a company, you confirm you may bind it.

Your account

One account per person. Keep your credentials to yourself — activity under your account is treated as yours. Tell us promptly if you think someone else has access.

Your code stays yours

You keep ownership of the solutions you write. You grant us only the permission needed to run them, store them against your account, show them back to you, and — where you ask for it — send them for an AI review.

Our content

Challenges, tests, quizzes, learning paths and the surrounding material belong to Atlas Code LLC. Use them to practise, personally. Do not republish them, resell them, or scrape the catalog in bulk.

Acceptable use

The sandbox runs code you submit. Do not use it to attack anything — ours or anyone else's — to mine cryptocurrency, to work around its limits, or to disrupt the service for other people. We may suspend an account that does.

Subscriptions and payment

Pro is billed monthly or yearly in advance through Lemon Squeezy, who acts as merchant of record — that is the name you will see on your invoice and on your card statement, not Atlas Code LLC. It renews automatically until you cancel, and cancelling takes effect at the end of the period you have already paid for — you keep access until then. Prices are on the pricing page; if they change, the change applies from your next renewal, not retroactively.

Refunds

Write to within 14 days of a charge and we will refund it. Statutory rights of withdrawal, where they apply to you, are unaffected by that.

Availability

We work to keep Codejump up but do not promise uninterrupted service: parts of it depend on third parties, and maintenance happens. The service is provided as is, and practising here is not a promise that you will pass any particular interview.

Ending things

You can delete your account whenever you like. We may suspend or close an account that breaks these terms or the law, and we will tell you why unless we are legally prevented from doing so.

Governing law

These terms are governed by the laws of the State of Wyoming, United States, without regard to its conflict-of-laws rules, and disputes arising from them go to the state or federal courts sitting in Laramie County, Wyoming.

If you are a consumer, that does not take away the protections of the law where you live: where your local law gives you rights that cannot be waived by contract — including the right to bring proceedings in your own courts — you keep them.

Changes and contact

If these terms change materially, the date at the top changes and we notify you before the change takes effect. Questions go to .
