Terms of Use

Effective date: August 11, 2026 Last updated: August 11, 2026

These Terms of Use (the “Terms”) constitute a binding agreement between you and Pop Logic Studios LLC, a California limited liability company (“Pop Logic Studios,” “we,” “us,” or “our”), governing your access to and use of the Bubble Sudoku mobile application (the “App”) and the website located at bubblesudoku.com, including the browser-based game hosted there (collectively with the App, the “Services”).

Please read these Terms carefully. By downloading, accessing, or using the Services, you agree to be bound by them. If you do not agree to these Terms, do not access or use the Services.

Summary

Bubble Sudoku is licensed to you for personal, non-commercial use on devices you own or control. The App and the browser-based game may be used without an account. Bubble Sudoku Plus is a single non-consumable purchase, processed and refunded by Apple or Google rather than by us. Gameplay data is stored on your device only and cannot be recovered by us if it is deleted. The artwork, characters, instructional text, and technique library are the property of Pop Logic Studios LLC; the sudoku puzzle form itself is in the public domain.

This summary is provided for convenience only and does not modify or replace the provisions set out below.

1. License Grant

Subject to your compliance with these Terms, Pop Logic Studios grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use the App on devices that you own or control, and to access and use the website, in each case for your personal, non-commercial entertainment purposes.

The Services are licensed to you, not sold. Pop Logic Studios reserves all rights not expressly granted in these Terms. No license is granted by implication, estoppel, or otherwise.

The App may be used without a network connection. Puzzles are generated on your device, and no account or registration is required to use the Services.

2. Restrictions on Use

You shall not, and shall not permit any third party to:

  • sell, rent, lease, lend, sublicense, distribute, or otherwise transfer the Services or any portion of them;
  • reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or underlying structure of the Services, except and only to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation;
  • modify, adapt, translate, or create derivative works based upon the Services;
  • reproduce, publish, or distribute the artwork, character designs, badge and trophy illustrations, instructional text, technique library, or other content of the Services, except as permitted under Section 7;
  • remove, obscure, or alter any proprietary notice contained in the Services;
  • access the Services by automated means, including scraping, crawling, or bulk downloading, or otherwise impose an unreasonable load on our infrastructure;
  • use the Bubble Sudoku name, logo, or trade dress in a manner likely to cause confusion as to affiliation, sponsorship, or endorsement;
  • interfere with or circumvent any feature of the Services, including for the purpose of falsifying scores, achievements, or daily challenge results; or
  • use the Services in violation of any applicable law or regulation.

Nothing in this Section restricts your personal use of puzzle solutions, notes, or instructional material for your own purposes or in ordinary discussion of the game.

3. In-App Purchases

The App offers Bubble Sudoku Plus, a single non-consumable in-app purchase that removes banner and full-screen advertising and provides unlimited hints. Bubble Sudoku Plus is not a subscription; it does not renew, and it does not expire. The optional video advertisement offered once per game in exchange for an additional life remains available to holders of Bubble Sudoku Plus and is not removed by the purchase.

All payments are processed by Apple Inc. or Google LLC, as applicable, in accordance with their respective terms of service. Pop Logic Studios is not a party to that transaction and does not receive payment card information. Refunds are administered exclusively by the applicable platform operator in accordance with its refund policy; we are unable to issue refunds directly.

Entitlements are associated with the App Store or Google Play account used to complete the purchase and may be restored to a new device using the restore function within the App and the same account. Because the Services do not maintain user accounts, entitlements cannot be transferred between platform accounts.

Purchases made on a device are the responsibility of the holder of the platform account associated with that device. Both platform operators provide parental controls and purchase authorization settings.

We reserve the right to modify the price, name, and composition of in-app purchases prospectively. Any such modification will not affect entitlements previously purchased. Material changes to the contents of an entitlement will be disclosed in the release notes accompanying the applicable version of the App.

4. Advertising

The free version of the App is supported by advertising. The categories of information collected in connection with advertising, the placements in which advertisements appear, and the controls available to you are described in our Privacy Policy.

Certain advertisements are optional video advertisements offered in exchange for an in-game benefit. Viewing them is voluntary, and no feature of the Services is conditioned upon doing so. Advertising inventory is supplied by a third party and may be unavailable at any given time, including when the device is offline. Where inventory is unavailable, the corresponding optional benefit is not offered. No benefit previously earned is withdrawn on that basis.

Pop Logic Studios does not select, review, endorse, or control the specific advertisements displayed within the App, and is not responsible for the content of third-party advertisements or for any transaction between you and an advertiser. Advertisements that appear to be fraudulent, deceptive, or otherwise objectionable may be reported to us at the address in Section 16.

5. Locally Stored Data

Gameplay progress, scores, statistics, badges, and settings are stored exclusively on your device. Pop Logic Studios does not maintain a copy of this data, does not provide backup or synchronization functionality, and is unable to recover it.

You acknowledge that deleting the App, clearing its data, clearing browser storage, or losing or replacing your device will result in the permanent loss of that data, and that Pop Logic Studios bears no liability for such loss. Entitlements to in-app purchases are restorable as described in Section 3.

6. Daily Challenge

Completion of the daily challenge in the browser-based game transmits the challenge date and the score achieved to our servers for aggregation into anonymous statistics, as described in the Privacy Policy. Submission of a score is an inherent part of participating in the daily challenge.

We may reset, correct, or discard aggregate results where a challenge is affected by a technical fault or by manipulation, and we may modify, suspend, or discontinue the daily challenge at any time.

7. Intellectual Property

Sudoku is a puzzle form in the public domain, and nothing in these Terms asserts any proprietary right in the puzzle form itself.

All right, title, and interest in and to the Services, including the software, source code, puzzle generation and hint engines, character designs and illustrations, badge and trophy artwork, instructional text and walkthroughs, technique library, color system, visual design, and the Bubble Sudoku name and logo, are and shall remain the exclusive property of Pop Logic Studios LLC and its licensors, and are protected by copyright, trademark, and other intellectual property laws.

You may reproduce screenshots of the Services for personal, editorial, review, educational, or news reporting purposes. Any other use of our content or marks requires prior written permission, which may be requested at the address in Section 16.

If you submit suggestions, feedback, or ideas concerning the Services, you grant Pop Logic Studios a perpetual, irrevocable, worldwide, royalty-free license to use them without restriction or compensation.

8. Third-Party Platforms

Where you obtain the App from the Apple App Store, the following additional terms apply. These Terms are concluded between you and Pop Logic Studios only, and not with Apple Inc. (“Apple”). Apple is not responsible for the App or its content. Apple has no obligation to furnish any maintenance or support services with respect to the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any; to the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App. Apple is not responsible for addressing any claim by you or a third party relating to the App, including product liability claims, claims of non-conformity with legal or regulatory requirements, and claims arising under consumer protection or similar legislation. Apple is not responsible for the investigation, defense, settlement, or discharge of any third-party claim that the App infringes intellectual property rights. You represent that you are not located in a country subject to a United States Government embargo or designated as a terrorist-supporting country, and that you are not listed on any United States Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce them against you.

Apple’s Licensed Application End User License Agreement additionally applies to the App as obtained through the App Store. In the event of a conflict between that agreement and these Terms with respect to the App, that agreement controls.

Where you obtain the App from Google Play, the Google Play Terms of Service additionally apply. Google LLC is not responsible for the App and is not a party to these Terms.

9. Modifications to the Services and to These Terms

We may modify, update, suspend, or discontinue the Services or any feature of them at any time, with or without notice. We do not warrant that any particular feature will remain available.

We may revise these Terms from time to time. Revised Terms will be posted on this page with an updated effective date, and material revisions will be noted in the release notes accompanying the applicable version of the App. Your continued use of the Services after the effective date of revised Terms constitutes acceptance of them. If you do not accept revised Terms, your remedy is to discontinue use of the Services.

10. Termination

These Terms remain in effect until terminated. You may terminate them at any time by ceasing all use of the Services and deleting the App. We may suspend or terminate your license immediately, without notice, if you materially breach these Terms.

Sections 2, 5, 7, and 11 through 15 survive any termination of these Terms.

11. Disclaimer of Warranties

The services are provided on an “as is” and “as available” basis, without warranty of any kind. To the maximum extent permitted by applicable law, Pop Logic Studios disclaims all warranties, whether express, implied, statutory, or otherwise, including the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement, and any warranties arising out of course of dealing or usage of trade. Pop Logic Studios does not warrant that the services will be uninterrupted, timely, secure, error-free, or free of harmful components, that defects will be corrected, or that the services will operate on any particular device or configuration.

Some jurisdictions do not permit the exclusion of implied warranties. To the extent such an exclusion is not permitted, the exclusions in this Section do not apply to you, and nothing in these Terms limits any non-waivable right afforded to you under the consumer protection law of your jurisdiction.

12. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall Pop Logic Studios LLC, its members, officers, employees, or agents be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, loss of profits, loss of goodwill, or business interruption, arising out of or relating to the services or these Terms, whether based in contract, tort, strict liability, or any other theory, and whether or not Pop Logic Studios has been advised of the possibility of such damages.

To the maximum extent permitted by applicable law, the aggregate liability of Pop Logic Studios arising out of or relating to the services or these Terms shall not exceed the greater of the amount you have paid to us for the services in the twelve months preceding the event giving rise to the claim, or twenty-five United States dollars.

Some jurisdictions do not permit the exclusion or limitation of certain damages. To the extent such an exclusion or limitation is not permitted, the provisions of this Section apply only to the fullest extent permitted in your jurisdiction, and nothing in these Terms excludes liability for fraud, for death or personal injury caused by negligence, or for any other liability that cannot lawfully be excluded.

13. Indemnification

You agree to indemnify, defend, and hold harmless Pop Logic Studios LLC and its members, officers, employees, and agents from and against any claim, demand, loss, liability, damage, cost, or expense, including reasonable attorneys’ fees, arising out of or relating to your breach of these Terms, your misuse of the Services, or your violation of applicable law or the rights of any third party.

14. Governing Law and Venue

These Terms and any dispute arising out of or relating to them or to the Services are governed by the laws of the State of California, without regard to its conflict of laws provisions. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

You and Pop Logic Studios agree that the state and federal courts located in Sacramento County, California shall have exclusive jurisdiction over any such dispute, and each party consents to the personal jurisdiction of those courts and waives any objection to venue in them.

If you are a consumer resident in a jurisdiction whose law affords you the right to bring proceedings in the courts of your place of residence or affords you the protection of its mandatory consumer law, this Section does not deprive you of that right or protection.

Before commencing proceedings, we ask that you contact us at the address in Section 16 so that we may attempt to resolve the matter informally.

15. General Provisions

Entire agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and Pop Logic Studios concerning the Services and supersede all prior agreements and understandings on that subject.

Severability. If any provision of these Terms is held to be invalid or unenforceable, that provision shall be enforced to the maximum extent permissible and the remaining provisions shall remain in full force and effect.

No waiver. Our failure to enforce any provision of these Terms shall not constitute a waiver of that provision or of any other provision.

Assignment. You may not assign or transfer these Terms or any rights under them without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.

Force majeure. Neither party shall be liable for any failure or delay in performance resulting from causes beyond its reasonable control.

Headings. Section headings are for convenience only and do not affect the interpretation of these Terms.
