Terms of Use

SAT Locker · Last updated November 3, 2026

Using these terms

By using the SAT Locker app for iPhone (the "App"), you agree to these terms and to Apple's Licensed Application End User License Agreement (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). If you do not agree, do not use the App.

You must be at least 13 years old. If you are under 18, a parent or guardian must agree to these terms for you and is responsible for any subscription bought for you.

What the App is

SAT Locker gives you SAT practice questions with explanations, a study plan and a projected score estimate. With your permission, it uses Apple's Screen Time to lock the apps you choose until you answer a question.

The projected score is an estimate based on your answers in the App. It is not an official score, and we do not guarantee any score, admission decision or other result.

SAT® is a trademark registered and owned by the College Board, which is not affiliated with and does not endorse this product. Our questions are written by us for practice and are not official SAT questions.

The lock on your apps

You choose the apps to lock in Apple's Screen Time picker. You can remove the lock at any time by turning off Screen Time access for the App in your iPhone Settings or by deleting the App. Emergency pauses follow the limits shown in the App.

Your account

The App creates an account for you the first time you open it, without asking for your name or email. You can add Sign in with Apple or an email and a password to keep your progress when you change phones. Keep your password private. You can delete your account at any time in the App: Settings, then Account and privacy, then Delete account.

Subscriptions

• The App's plan is an auto-renewable subscription sold through Apple's App Store. It gives you the questions, the explanations, the study plan and the projected score. The price, the length of each period and any free trial are shown on the screen before you confirm the purchase.
• Payment is charged to your Apple Account when you confirm. The subscription renews automatically at the same price for the same period unless you turn off auto-renew at least 24 hours before the current period ends.
• Some extras, like the practice tests, are sold as a one-time purchase through Apple. You pay once, the purchase stays with your Apple Account, and Restore purchases brings it back on another iPhone.
• You can manage or cancel the subscription in your iPhone's Settings (your name, then Subscriptions) or in the App (Settings, then Subscription, then Manage subscription). Canceling stops the next renewal, and you keep access until the end of the period you paid for.
• If you bought the plan on our website instead of the App Store, sign in to the App with the same email you used at checkout to use it. That purchase is billed by our website checkout, and you can cancel it by writing to support@satlocker.app. Refunds for website purchases are handled by us at the same address.
• If a free trial is offered, any unused part of it ends when you buy a subscription.
• When your subscription ends, the App removes the lock from your apps.
• Refunds for App Store purchases are handled by Apple at https://reportaproblem.apple.com.
• Deleting your account does not cancel an App Store subscription. Cancel it first if you want the charges to stop.

Acceptable use

• Use the App for your own studying.
• Do not copy, sell, publish or scrape the questions or the explanations.
• Do not try to break, overload or get around the limits or the security of the App or our servers.
• Do not use the App to break the law or to harm others.
• Do not choose a nickname or a challenge name that is offensive, abusive or objectionable. We review reports about nicknames and challenges within 24 hours, and we may remove the nickname, the challenge or the person who broke this rule.

Our content

The SAT Locker name, logo, cat mascot, design, questions, explanations and scoring method belong to us.

Disclaimer and limits

The App is provided "as is" and "as available", without promises that it will always work or be free of errors. To the fullest extent the law allows, we are not liable for indirect or consequential losses, and our total liability for any claim is limited to the amount you paid for the App in the 12 months before the claim.

Changes and ending

We may update these terms or the App. When we change the terms in a way that matters, we will update the date at the top of this page. You can stop using the App and delete your account at any time, and we may suspend access if these terms are broken.
