Quill & Star

Terms of Use

Effective date: October 9, 2026

These terms are the agreement between you and KHKikani, the independent developer in India who makes Quill & Star. They cover the Quill & Star app and this website. We’ve kept them as plain as we can.

1. Agreeing to these terms

By downloading, installing or using Quill & Star, or using this website, you agree to these terms and to our Privacy Policy, which explains how information is handled. If you don’t agree, please don’t use the app or the website.

To accept these terms you must be old enough to make a binding agreement where you live, or have the permission of a parent or guardian who agrees to them for you. Quill & Star is made for adults and isn’t directed to children under 13.

2. Your license to use the app

We give you a personal, non-exclusive, non-transferable, revocable license to download and use Quill & Star for your own non-commercial enjoyment, on devices you own or control, as the rules of the store you got it from allow (Apple’s App Store or Google Play).

The app is licensed to you, not sold. We and our licensors keep every right not expressly given to you here.

3. Free, with ads

Quill & Star is free to download and play, and it’s supported by ads from Google AdMob. Today the app has no in-app purchases and no subscriptions.

  • A banner may appear at the foot of the menu pages.
  • Full-screen ads may appear after you solve a puzzle, never in the middle of one.
  • Rewarded ads, for a hint, one more try or a streak freeze, appear only when you choose to watch one.
  • Ads come from Google and its ad partners. We ask Google to show only ads suitable for a general audience, but we don’t write or check every ad, and we aren’t responsible for what advertisers offer. Anything you buy from an advertiser is between you and that advertiser.

We may change how often and where ads appear, switch ads off for a while, or change other features. If we ever add something you pay for, the price and terms will be shown before you buy, and the store’s payment terms will apply.

4. Your progress

Your puzzles, progress, streaks, streak freezes and settings are stored only on your phone. We don’t back them up or sync them, so they can be lost if you delete the app, clear its data or change phones without carrying them over. Streaks, streak freezes, hints and other things you earn in the game have no cash value and can’t be sold, transferred or exchanged for anything.

5. Fair play

Please enjoy the game as it’s meant to be played, and don’t:

  • copy, sell, rent, sublicense or redistribute the app or its puzzles, or offer them as part of another product or service;
  • decompile, reverse engineer or take apart the app, except where the law allows it despite this restriction;
  • interfere with the app’s ads, for example by tapping ads you’re not interested in to generate revenue, or by using scripts, bots or automated tapping;
  • use the app to break any law or to harm anyone;
  • remove or change any copyright, trademark or license notices;
  • use our name, wordmark or icon in a way that suggests we endorse you or your product.

Sharing your results with the Share button, talking about the game, and posting screenshots for personal, non-commercial purposes are all welcome.

6. Who owns what

The app, its puzzles and the code that generates them, its design, text, sounds and icon, and this website belong to KHKikani or our licensors and are protected by copyright and other laws. The name “Quill & Star”, its wordmark and its icon are our trademarks. The rules of this kind of logic puzzle aren’t owned by anyone; our puzzles, code and design are ours.

The app and this website use four typefaces, each licensed under the SIL Open Font License, Version 1.1:

  • Libre Baskerville, copyright 2012 The Libre Baskerville Project Authors, with Reserved Font Name Libre Baskerville;
  • Crimson Pro, copyright 2018 The Crimson Pro Project Authors;
  • Work Sans, copyright 2019 The Work Sans Project Authors;
  • Nothing You Could Do, copyright 2010 Kimberly Geswein.

The full license texts, and the licenses of the open-source software the app is built with, are in the app under Settings > About Quill & Star > Licenses.

If you send us ideas or suggestions, we may use them without owing you anything, and we’re grateful for them.

7. Services from other companies

The app relies on services from Google: Firebase for usage statistics, crash reports and remote settings, and AdMob for ads. This website is hosted by Google on Firebase Hosting. Your use of the app is also subject to the terms of the store you downloaded it from, and to any terms that apply to your device and your mobile data plan. We aren’t responsible for services, websites or content that other companies run, including ads and the store pages we link to.

8. If you got the app from Apple’s App Store

On iPhone and iPad, your use of Quill & Star is governed by Apple’s Licensed Application End User License Agreement (the “Standard EULA”). These terms add to it. If they conflict, the Standard EULA wins. In addition:

  • Who you’re agreeing with. These terms are between you and KHKikani only, not Apple. KHKikani, not Apple, is solely responsible for the app and its content.
  • Scope of license. Your license is limited to using the app on Apple-branded products that you own or control, as allowed by the Usage Rules in the Apple Media Services Terms and Conditions, except that the app may be accessed and used by other accounts associated with you through Family Sharing or volume purchasing.
  • Maintenance and support. KHKikani is solely responsible for any maintenance and support of the app, as described on our Support page. Apple has no obligation to provide any maintenance or support for the app.
  • Warranty. KHKikani is solely responsible for any product warranties, whether express or implied by law, to the extent they haven’t been effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, for the app. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are KHKikani’s sole responsibility.
  • Product claims. KHKikani, not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession or use of it, including product liability claims, claims that the app fails to conform to any applicable legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
  • Intellectual property. If a third party claims that the app or your possession and use of it infringes their intellectual property rights, KHKikani, not Apple, is solely responsible for the investigation, defense, settlement and discharge of that claim.
  • Legal compliance. You confirm that you aren’t 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 that you aren’t listed on any U.S. Government list of prohibited or restricted parties.
  • Developer contact. Questions, complaints or claims about the app go to KHKikani, India, at harshitkikani9081@gmail.com or +91 95122 03345.
  • Third-party terms. You must comply with any applicable third-party terms when using the app, such as your mobile data plan.
  • Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these terms, and once you accept them, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

9. If you got the app from Google Play

Your download and use of the app are also subject to the Google Play Terms of Service. Google isn’t responsible for the app or its content.

10. No guarantees

We take care over every puzzle, and each one is checked by our solver to have exactly one answer. Even so, the app and this website are provided “as is” and “as available”. To the extent the law allows, we make no promises or warranties, express or implied, including that the app will always be available, free of errors or compatible with your device, that ads, reminders or other features will always work, or that your progress will never be lost. Some places don’t allow these exclusions, so some of them may not apply to you.

11. Limits on our liability

To the extent the law allows, KHKikani isn’t liable for any indirect, incidental, special, consequential or punitive damages, or for lost data, lost profits or lost opportunities, arising from your use of, or inability to use, the app or this website. To the extent the law allows, our total liability to you for all claims about the app and this website is limited to the greater of the amount you paid us for the app in the 12 months before the claim (for a free app, nothing) and US $50.

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that can’t be limited or excluded by law.

12. Your rights as a consumer

These terms don’t take away any rights you have as a consumer that can’t be waived or changed by contract.

  • EU and UK. If you live in the European Union or the United Kingdom, you keep the protections that consumer law gives you, including any legal guarantee for digital content, and we’re responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. The limits in sections 10 and 11 apply only as far as your local law allows.
  • United States. Some states don’t allow the exclusion of implied warranties or the limitation of incidental or consequential damages, so some of the limits above may not apply to you, and you may have other rights that vary from state to state.
  • Everywhere else. Mandatory consumer protections where you live still apply.

13. Changes to the app and to these terms

We’re always working on Quill & Star, so the app will change, and we may add, change or remove features. We may also update these terms. When we do, we’ll change the effective date at the top. If a change matters to how you use the app, we’ll say so on this page and in the app’s release notes before it takes effect. If you keep using the app after a change takes effect, the new terms apply. If you don’t agree with them, you can stop using the app and delete it.

14. Ending this agreement

You can end this agreement at any time by deleting the app and no longer using this website. We may suspend or end your license if you seriously or repeatedly break these terms, or if we have to for legal reasons. We may also stop offering the app, in which case it may stop working or stop receiving updates. Sections 4, 6, 10, 11, 12, 15 and 16 continue to apply after this agreement ends.

15. Governing law and disputes

These terms are governed by the laws of India. The courts of India have jurisdiction over any dispute about the app, this website or these terms. If you’re a consumer living outside India, you also keep the protection of the mandatory laws of the country where you live, and you may bring a claim in your local courts where your local law allows.

Before starting any formal claim, please contact us. Most problems can be fixed with an email.

16. General

  • If any part of these terms is found unenforceable, the rest stays in effect.
  • If we don’t enforce a part of these terms straight away, we haven’t given up the right to do so later.
  • These terms, the Privacy Policy and, on iPhone and iPad, Apple’s Standard EULA are the whole agreement between you and us about Quill & Star.
  • You may not transfer your rights under these terms to anyone else. We may transfer ours to someone who takes over the app, and they’ll be bound by these terms.
  • You must follow all export control and sanctions laws that apply to your use of the app.
