Terms of Use

1. Acceptance & Eligibility

These Terms govern your use of the Game, including all of its software, level data, artwork, textures, audio and any updates we release. They apply together with our Privacy Policy, which is incorporated into these Terms by reference.

The Game is intended for players aged 13 and over. If you are under the age of majority in your country, you may use the Game only with the consent and supervision of a parent or legal guardian, who accepts these Terms on your behalf and is responsible for any purchases you make.

Your use of the Game is also subject to the rules of the platform you obtained it from — the Apple Media Services Terms and Conditions for the App Store, and, when the Android version is released, the Google Play Terms of Service.

2. Licence Grant & Restrictions

Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to download, install and run one copy of the Game on devices that you own or control, solely for your personal, non-commercial entertainment. This licence is granted, not sold: we and our licensors retain all ownership of the Game.

On Apple devices, this licence is limited to use on any Apple-branded products that you own or control, and as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions, except that the Game may be accessed by other accounts associated with you via Family Sharing or volume purchasing.

You agree not to:

• Copy, modify, translate, adapt or create derivative works of the Game, except where such restriction is prohibited by applicable law.
• Decompile, reverse engineer, disassemble or otherwise attempt to derive the source code or the level data of the Game, except to the extent that applicable law expressly permits it despite this restriction.
• Rent, lease, lend, sell, redistribute, sublicense or commercially exploit the Game or any part of it.
• Remove, obscure or alter any copyright, trademark or other proprietary notices.
• Circumvent, disable or tamper with any security, purchase-verification or advertising feature of the Game.

3. Virtual Coins & Studio Items

The Game includes a virtual currency ("Coins") that you earn by completing puzzles, earning stars, keeping a daily check-in streak, or watching optional rewarded video ads — and that you may also buy as an optional in-app purchase. Coins are spent on hints and on Studio items such as block materials, pedestals and guide colours.

• Licence, not property: Coins and Studio items are a limited licence to use digital features inside the Game. You do not own them.
• No real-world value: they cannot be exchanged for money, gift cards, goods or anything of value outside the Game, and they have no cash value.
• Non-transferable: Coins and unlocked items are tied to the installation on your device. Because the Game stores progress locally and offers no cloud save, uninstalling the Game or changing device permanently deletes your Coins, progress and unlocked items, and we cannot restore them. Purchases made through the App Store can be restored through the platform's "Restore Purchases" function; earned Coins and earned unlocks cannot.
• Changes: we may adjust prices, rewards, drop rates or the balance of the Game in updates. We will not revoke Coins or items you have properly earned or paid for except in cases of fraud, chargeback or breach of these Terms.

4. In-App Purchases, Billing & Refunds

The Game offers optional in-app purchases: a one-time "Remove Ads" unlock, a one-time Starter Pack (Remove Ads plus a coin bonus), and consumable Coin packs. Prices are shown in the Game in your local currency before you confirm, and include applicable taxes where the platform collects them.

• Payment processing: all payments are processed by Apple through the App Store (and, when released, by Google through Google Play) under their terms and with their payment methods. We never receive or store your payment details.
• Delivery: consumable Coins are credited to your local save immediately after the platform confirms the purchase. The "Remove Ads" unlock is a non-consumable and can be restored on the same platform account.
• Refunds: refund requests must be made to Apple (or Google) under their refund policies — we have no access to your payment instrument or transaction history and cannot issue refunds directly. Nothing here limits any refund rights you have under mandatory consumer law.
• EU/EEA and UK right of withdrawal: digital content is supplied immediately upon purchase. By confirming a purchase you request immediate performance and acknowledge that you lose your 14-day right of withdrawal once the content has been delivered, to the extent permitted by law.
• Unauthorised purchases: you are responsible for purchases made on your device. Use your platform's parental controls or purchase-confirmation settings to prevent unwanted purchases by children.

5. Advertising

The Game is free to download and is funded partly by advertising supplied by Google AdMob: optional rewarded video ads that you choose to watch for extra Coins or hints, and interstitial ads that may appear between levels. Ads never interrupt you while you are solving a puzzle. Buying the "Remove Ads" unlock or the Starter Pack permanently removes interstitial ads; rewarded ads remain available for you to start whenever you want the coins.

Advertisements are served by a third party and their content is not under our control. How advertising data is handled, and how to change your advertising choices, is described in our Privacy Policy.

6. Intellectual Property

All rights, title and interest in and to the Game — including its mechanics, voxel models, level designs, diorama concepts, shaders, user interface, sound design, code, graphics and the "Block Sculpture: 3D Puzzle" name and logo — are and remain the exclusive property of SON PHI and its licensors, protected by copyright and other intellectual property laws.

You may capture and share screenshots and video of your own gameplay, including on monetised channels, provided you do not present the material as an official product and do not use it in a way that is misleading or that harms the Game's reputation. All rights not expressly granted in these Terms are reserved.

7. User Conduct

When using the Game or contacting our support, you agree not to:

• Use automated scripts, bots, memory editors, modified clients or other cheats to manipulate Coins, progression or advertising rewards.
• Attempt to obtain in-app purchases without paying, or to falsify purchase receipts.
• Interfere with, disrupt or place undue load on the third-party services the Game relies on.
• Behave abusively, fraudulently or unlawfully towards us or anyone else in connection with the Game.

8. Updates, Availability & Termination

We may release updates that add, change or remove features, and we may discontinue the Game or stop supporting particular devices or operating system versions. We are not obliged to keep the Game available indefinitely.

This licence remains in effect until terminated. It terminates automatically if you breach these Terms, and you may terminate it at any time by deleting the Game from your devices. On termination you must stop using the Game; sections 3, 6, 9, 10, 12 and 13 survive termination. Termination does not entitle you to a refund of amounts already paid, except where mandatory law provides otherwise.

9. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE GAME IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT.

We do not warrant that the Game will be uninterrupted or error-free, that defects will be corrected, or that it will be compatible with every device. Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you; in those jurisdictions you may have statutory rights that these Terms do not limit.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL OR GAME PROGRESS, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE GAME.

Our total aggregate liability arising out of or relating to these Terms or the Game shall not exceed the greater of (a) the total amount you paid us or the platform for the Game and its in-app purchases in the twelve months before the event giving rise to the claim, or (b) USD 50.

Nothing in these Terms excludes or limits our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded under applicable law. If you are a consumer, you keep all mandatory rights granted to you by the consumer law of your country of residence.

11. Apple-Required Terms

The following applies to the version of the Game obtained through the Apple App Store:

• Acknowledgement: these Terms are concluded between you and SON PHI only, and not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the Game and its content.
• Scope of licence: the licence granted in section 2 is limited to a non-transferable licence to use the Game on Apple-branded products you own or control, as permitted by the Usage Rules of the Apple Media Services Terms and Conditions.
• Maintenance and support: we are solely responsible for providing any maintenance and support for the Game, as specified in these Terms or as required by applicable law. Apple has no obligation whatsoever to furnish any maintenance or support services.
• Warranty: we are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the Game to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the Game to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Game.
• Product claims: we, not Apple, are responsible for addressing any claims relating to the Game or your possession and use of it, including product liability claims, any claim that the Game fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation.
• Intellectual property claims: in the event of any third-party claim that the Game or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of any such claim.
• Legal compliance: you represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party terms: you agree to comply with applicable third-party terms of agreement when using the Game (for example, your wireless data service agreement).
• Third-party beneficiary: Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
• Developer contact: questions, complaints and claims regarding the Game should be directed to SON PHI, Ha Dong, Ha Noi, Vietnam, pvsasoftware@gmail.com.

12. Governing Law & Disputes

These Terms are governed by the laws of Vietnam, without regard to its conflict-of-laws rules. The courts of Ha Noi, Vietnam shall have jurisdiction over any dispute arising out of or in connection with these Terms.

If you are a consumer resident in the European Union, the United Kingdom or another jurisdiction whose law grants you the protection of mandatory consumer provisions, nothing in this section deprives you of that protection or of the right to bring proceedings in the courts of your place of residence.

Before starting formal proceedings, please contact us at pvsasoftware@gmail.com — most issues can be resolved quickly by email.

13. General Provisions

• Changes to these Terms: we may update these Terms, for example when features change. The updated version is published at this URL with a new "Last Updated" date, and material changes take effect the next time you use the Game after publication. If you do not agree with a change, stop using the Game and delete it.
• Severability: if any provision is held invalid or unenforceable, the remaining provisions stay in full force, and the invalid provision is replaced by a valid one that comes closest to its intended effect.
• No waiver: our failure to enforce a provision is not a waiver of our right to enforce it later.
• Assignment: you may not assign or transfer these Terms. We may assign them to a successor in connection with a merger, acquisition or sale of assets.
• Entire agreement: these Terms together with the Privacy Policy constitute the entire agreement between you and us regarding the Game, and supersede any prior agreements.
• Force majeure: we are not liable for delays or failures caused by events beyond our reasonable control.
