Terms of use

Effective November 12, 2026

These terms cover the Loomoku app, the browser game and this website. They are written to be read. By using Loomoku you agree to them.

1. About these terms

Loomoku: Cozy Sudoku (the "app"), the browser game at loomoku.com/play and the website loomoku.com (together, "Loomoku") are provided by Silvergrove Labs LLC ("we", "us", "our"). These terms, including the licence in them, are an agreement between you and Silvergrove Labs LLC. If you do not agree to them, please do not use Loomoku. If you are under the age of majority where you live, please read these terms with a parent or guardian.

2. Your licence

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use the app on Apple-branded devices that you own or control, and to play the browser game, for your own non-commercial enjoyment. The app is licensed to you, not sold. We keep all rights we do not expressly grant.

3. If you got the app from the App Store

These terms are the end user licence agreement for the app. The following provisions apply to the app as downloaded from Apple's App Store:

  1. Agreement with us, not Apple. These terms are between you and Silvergrove Labs LLC only, and not with Apple Inc. ("Apple"). Silvergrove Labs LLC, not Apple, is solely responsible for the app and its content.
  2. Scope of licence. Your licence is limited to using the app on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the app may also be used by other accounts associated with you through Family Sharing or volume purchasing.
  3. Maintenance and support. Silvergrove Labs LLC is solely responsible for any maintenance and support of the app, as described in these terms or as required by law. Apple has no obligation to provide any maintenance or support for the app.
  4. Warranty. Silvergrove Labs LLC is solely responsible for any product warranties, whether express or implied by law, to the extent they are not 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 you. To the maximum extent permitted by law, Apple has no other warranty obligation at all with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses caused by a failure to conform to a warranty are the responsibility of Silvergrove Labs LLC, to the extent they are not disclaimed by these terms.
  5. Product claims. Silvergrove Labs LLC, not Apple, is responsible for addressing any claims by you or any third party relating to the app or your possession and use of it, including (a) product liability claims, (b) any claim that the app fails to conform to any applicable legal or regulatory requirement, and (c) claims arising under consumer protection, privacy or similar legislation.
  6. Intellectual property claims. If any third party claims that the app or your possession and use of it infringes that third party's intellectual property rights, Silvergrove Labs LLC, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim.
  7. Legal compliance. You represent and warrant that you are not located in a country that is subject to a United States Government embargo or that has been designated by the United States Government as a "terrorist supporting" country, and that you are not listed on any United States Government list of prohibited or restricted parties.
  8. Developer contact. Questions, complaints or claims about the app should be sent to Silvergrove Labs LLC at support@loomoku.com.
  9. Third-party terms. You must comply with any applicable third-party terms when using the app, such as your mobile data or internet service agreement.
  10. Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these terms. Once you accept these terms, Apple will have the right, and will be deemed to have accepted the right, to enforce them against you as a third-party beneficiary.

4. Fair use

Please do not:

  • copy, sell, rent, sublicense or redistribute Loomoku or its artwork, music, sounds or text, except for Tiles and screenshots you share for personal, non-commercial purposes;
  • reverse engineer, decompile, disassemble or modify Loomoku, except where the law says this cannot be restricted;
  • use automated tools to scrape or overload the website, or try to interfere with leaderboards, achievements or other players' experience;
  • use Loomoku in any way that breaks the law.

5. Ownership and feedback

Loomoku, including its name, logo, software, puzzles as presented, design, felt artwork, music and sounds, belongs to Silvergrove Labs LLC and its licensors and is protected by copyright, trademark and other laws. These terms do not give you any rights in it beyond the licence above. The Tiles you earn are yours to share for personal, non-commercial purposes.

If you send us ideas or suggestions, you agree that we may use them freely, without any obligation to you.

6. Spools, Hints and other in-game items

Spools, Hints, streak freezes, board themes, quilt palettes, Tile frames and similar items are features of the game, not property. You receive a limited licence to use them within the game. They have no cash or monetary value, cannot be exchanged for money or anything of value outside the game, cannot be transferred to another person, and are not refundable. In the current version they are earned only by playing. We may change how they are earned, priced or used as the game develops, and they may be lost if your progress is lost.

7. Your progress

App progress is stored on your device and, if you use it, in your own iCloud account. Browser progress is stored in your browser and does not transfer to the app. You can make a backup at any time with Export progress in the app's Settings. We cannot see your progress, so we cannot restore it if it is lost when the app is deleted, a device is reset or browser data is cleared.

8. Apple services and other websites

Game Center, iCloud and the App Store are provided by Apple under Apple's own terms and privacy policy, and their availability is up to Apple. Links from Loomoku to other websites are provided for convenience. We are not responsible for services or websites that we do not run.

9. Privacy

Our privacy policy explains what Loomoku does and does not do with data. In short, we do not collect personal data.

10. Changes to Loomoku

We may update, change, suspend or discontinue any part of Loomoku, including the browser game, at any time. We try to make changes that improve the game, and we will keep saved progress working across updates where we reasonably can.

11. No warranty

Loomoku is provided "as is" and "as available". To the fullest extent the law allows, Silvergrove Labs LLC makes no warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement, and does not promise that Loomoku will be uninterrupted, error free or available on every device. Some places do not allow these exclusions, so some of them may not apply to you.

12. Limit of liability

To the fullest extent the law allows, Silvergrove Labs LLC will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, progress or in-game items, arising from or relating to your use of Loomoku. Our total liability for all claims relating to Loomoku is limited to the greater of the amount you paid for the app in the twelve months before the claim and fifty US dollars (US$50).

Nothing in these terms limits liability that cannot be limited by law, such as liability for death or personal injury caused by negligence or for fraud, or any rights you have as a consumer under the laws of the place where you live.

13. Ending these terms

You can stop using Loomoku at any time by deleting the app and leaving the website. Your licence ends automatically if you break these terms, and when it ends you must stop using the app and delete it. Sections 3, 5, 6, 11, 12, 14 and 15 continue to apply after the licence ends.

14. Governing law and disputes

These terms are governed by the laws of the State of California, United States, without regard to its conflict of law rules. If you have a concern, please write to us first so we can try to resolve it informally. If we cannot resolve it within 30 days, the state and federal courts located in California have jurisdiction over any dispute about these terms or Loomoku. If you are a consumer living in the European Union, the United Kingdom or another country whose laws give you the right to bring a claim in your local courts, or to the protection of your local laws, nothing in this section takes that right away.

15. General

These terms, together with our privacy policy, are the whole agreement between you and us about Loomoku. If any part of these terms is found to be unenforceable, the rest stays in effect. If we do not enforce a part of these terms straight away, we can still enforce it later. You may not transfer your rights under these terms to anyone else. We may transfer ours to another organisation that takes over Loomoku, and your rights will not be reduced as a result.

16. Changes to these terms

We may update these terms from time to time. We will post the new version here and change the effective date at the top. If a change is significant, we will give reasonable notice, for example on this website or in the app. If you keep using Loomoku after an update takes effect, the new terms apply.
