Terms of Service

Your account

You must be at least 13 to use TweakCode. You sign in with Google or GitHub and are responsible for what happens under your account. An account is for one person. Do not share it or resell access to it.

Plans and billing

• Part of TweakCode is free. Paid plans unlock the rest and are charged through Stripe at the price shown on the pricing page when you buy.
• The 3-month sprint is one payment for 90 days of access from purchase. It ends on its own and never charges again.
• Founder lifetime is one payment with no renewal.
• Annual and existing monthly subscriptions renew automatically at the end of each period until you cancel. You can cancel at any time from Manage billing in the account menu, and access continues until the paid period ends.
• We may change prices. A new price applies only from your next renewal after we tell you about it, so you have time to cancel first.
• Prices may not include taxes that apply where you live.

Cancellation and refunds are covered in the refund policy.

Our content

Lessons, explanations, visualizations, problems, and tests on TweakCode belong to us. You may use them for your own learning. Do not copy, republish, sell, or scrape them, and do not use them to build a competing course or problem set.

Many problems are original problems modeled on well-known interview questions. TweakCode is not affiliated with or endorsed by LeetCode, NeetCode, or any company named on the site.

Your code

You own the code you write. You let us store it, run it in our judge, and show it back to you, only to operate the site.

Acceptable use

• Do not use the code judge to attack, probe, or overload our servers or anyone else's, mine cryptocurrency, or run anything unrelated to solving the problem.
• Do not try to read hidden tests, other users' data, or parts of the site you do not have access to.
• Do not get around run limits, paid access, or other restrictions.
• Do not use the site to break the law.

We may suspend or close an account that breaks these rules.

No guarantees

TweakCode is provided as it is. We work to keep it accurate and available, but we do not promise that it will be error-free or always online, or that it will get you a job or an offer.

Limits on liability

To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability for any claim about TweakCode is limited to what you paid us in the 12 months before the claim.

Ending the agreement

You can stop using TweakCode and cancel your plan at any time. We may end or suspend your access if you break these terms. Sections about our content, liability, and governing law continue after the agreement ends.

Governing law

These terms are governed by the laws of the State of California, without regard to its conflict-of-law rules.

Changes and contact

If we change these terms, we will update the date at the top. For a significant change, we will tell signed-in users before it takes effect. Questions go to tweakcode.support@gmail.com. How we handle your data is described in the privacy policy.
