Terms of Service

Last updated: May 31, 2026

These Terms govern your use of the Screen Star iPhone app and the getscreenstar.com website (together, the "Service"). The Service is operated by Nam Bui, a sole proprietor based in New York ("Screen Star," "we," or "us"). By installing, opening, or using the Service, you agree to these Terms. If you don't agree, don't use the Service.

These Terms incorporate our Privacy Policy by reference.

1. What Screen Star is (and isn't)

Screen Star is a screen-time utility for iPhone. It uses Apple's Family Controls and DeviceActivity frameworks to help you set a daily time budget on apps and categories you choose, displays usage charts, optionally shields blocked apps, and shows a cartoon mascot that reacts to your behavior.

Screen Star is not a medical device, therapy, addiction treatment, or substitute for professional help. It is a self-directed productivity and habit tool.

2. Eligibility

You must be at least 13 years old to use Screen Star, and old enough in your country to enter into a binding contract. If you are under the age of majority where you live, you may only use the Service with permission and supervision from a parent or legal guardian who agrees to these Terms on your behalf.

Screen Star uses Family Controls in its individual-device mode. It is not designed or marketed as a parental-control product.

3. Your license to use the app

Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use Screen Star on Apple-branded devices that you own or control, for your own personal, non-commercial use. All other rights are reserved.

You may not (and may not permit anyone else to):

• Copy, modify, adapt, translate, or create derivative works of the app
• Reverse-engineer, decompile, or attempt to extract source code, except to the extent that applicable law expressly permits despite this limitation
• Rent, lease, lend, sell, sublicense, or otherwise transfer the app
• Remove or alter any copyright, trademark, or other proprietary notices
• Use the app to build a competing product or to scrape, train, or benchmark another model or service

4. Subscriptions, billing, and refunds

Screen Star offers an auto-renewable subscription that unlocks paid features. By starting a subscription you agree to the following terms, which are standard for App Store subscriptions:

• Charge. Payment is charged to your Apple ID at confirmation of purchase.
• Auto-renewal. Your subscription automatically renews at the end of each billing period (e.g., weekly, monthly, or yearly) at the then-current price, unless you cancel at least 24 hours before the period ends.
• Renewal charge. Your Apple ID is charged for renewal within 24 hours before the current period ends.
• Manage and cancel. You can manage or cancel your subscription anytime in Settings → [your name] → Subscriptions on your iPhone. Deleting the app does not cancel your subscription.
• Free trials. If a free trial is offered, any unused portion is forfeited when you purchase the subscription, where Apple's terms require.
• Refunds. All sales are processed by Apple. Refund requests are handled by Apple at reportaproblem.apple.com, subject to Apple's policies. We cannot issue refunds directly.
• Price changes. If we change the subscription price, Apple will notify you in advance as required, and you'll have the chance to accept or cancel before the new price applies.

5. Acceptable use

You agree not to use Screen Star to do anything illegal, to circumvent Apple's Family Controls protections in a way that harms another person, or to interfere with the Service's normal operation (e.g., by attacking our servers, abusing the website's API, or attempting to falsify subscription receipts). We may suspend access to the Service if you do.

6. Our intellectual property

Screen Star, including the yellow-star mascot characters and all related artwork, the app and website code, the visual design, the brand name, and all related materials, is owned by Nam Bui and protected by U.S. and international copyright, trademark, and other intellectual-property laws. These Terms do not transfer any ownership to you.

Anything you create within the app that stays on your device (your settings, your budget, your streaks) is yours.

7. No medical or professional advice

8. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION.

We do not warrant that Apple's Screen Time frameworks (Family Controls, DeviceActivity, ManagedSettings) will perform without error or that usage data, thresholds, shield triggers, widgets, or notifications will always be accurate or on time. These are Apple system features that we use as Apple provides them.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL SCREEN STAR OR NAM BUI BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE SERVICE.

OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD $50.

Some jurisdictions do not allow the limitation or exclusion of liability for certain damages, so some of the above may not apply to you.

10. Indemnification

You agree to defend, indemnify, and hold harmless Nam Bui from and against any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your use of the Service, your violation of these Terms, or your violation of any rights of a third party.

11. Termination

You can end this agreement at any time by deleting the app and cancelling any active subscription through Apple. We can suspend or terminate your access if you materially violate these Terms or if continuing to provide the Service to you would expose us to legal risk. Sections that by their nature should survive (IP, disclaimers, liability limits, indemnity, governing law) will survive termination.

12. Apple-specific terms

These Terms are between you and Nam Bui. They are not with Apple. Because Screen Star is distributed through Apple's App Store, the following apply (Apple requires them):

• Apple is not a party. Apple is not responsible for the Service or its content, and is not a party to these Terms.
• Scope of license. The license granted in Section 3 is limited to a non-transferable license to use Screen Star on any Apple-branded device that you own or control, as permitted by Apple's App Store Terms of Service. You may use Screen Star on devices associated with your Apple ID through Family Sharing or volume purchasing where Apple permits.
• Maintenance and support. Nam Bui, not Apple, is solely responsible for providing any maintenance and support for Screen Star.
• Warranty. Nam Bui is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If Screen Star fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for Screen Star to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to Screen Star.
• Product claims. Nam Bui, not Apple, is responsible for addressing any claims by you or any third party relating to Screen Star or your possession and use of it, including (a) product liability claims, (b) any claim that Screen Star fails to conform to any applicable legal or regulatory requirement, and (c) claims arising under consumer protection, privacy, or similar legislation.
• Intellectual property. If a third party claims that Screen Star or your possession and use of it infringes that third party's intellectual property rights, Nam Bui, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such claim.
• Legal compliance. You represent and warrant that (a) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country, and (b) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

13. Governing law and disputes

These Terms are governed by the laws of the State of New York, USA, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Informal resolution first. Before filing any claim, you agree to try to resolve the dispute informally by emailing [email protected] with a description of the issue. We'll do the same. If we can't resolve it within 60 days, either of us can pursue formal action.

Venue. Any lawsuit must be brought in the state or federal courts located in New York County, New York, and you and we consent to personal jurisdiction there. You and we both waive any right to a jury trial to the extent permitted by law.

Nothing in this section prevents either party from seeking relief in small-claims court for qualifying disputes, or from seeking injunctive relief in any court of competent jurisdiction to protect intellectual property.

14. Changes to these Terms

We may update these Terms when the Service changes or the law requires. If we make material changes, we'll update the "Last updated" date and surface a notice in the app the next time you open it. Continuing to use the Service after a change means you accept the updated Terms.

15. Miscellaneous

• Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us regarding the Service.
• Severability. If any provision is held unenforceable, the rest stays in effect.
• No waiver. Failing to enforce a right is not a waiver of that right.
• Assignment. You may not assign these Terms. We may assign them to a successor in a sale, merger, or reorganization.
• No agency. Nothing here creates an agency, partnership, or employment relationship.
