Provider and scope
These terms describe Sudoku byBnD and the byBnD Games information and support website. The provider is BYBND INFORMÁTICA LTDA, CNPJ 32.574.894/0001-10, at Alameda dos Maracatins, 1435 - Conjunto 307 - Indianópolis, São Paulo - SP, 04089-015, Brazil. Contact us at contato@bybnd.com.br. By installing or using the game, you agree to these terms.
The app licence supplied with your download and any mandatory local law also apply. This page does not retroactively replace an existing licence or reduce rights you already hold. Reading a privacy policy is not consent to unrelated data processing.
The game
Sudoku byBnD is a free mobile game with easy, medium and hard puzzles, a training puzzle, pencil notes, undo, progress saved on your device, history and statistics. It needs no account and works without an internet connection. It has no cloud save, subscription, currencies or randomised items.
The game is made for a general audience aged 13 and over and is not directed to children under 13. Supported devices and the countries where the game is available depend on the version and the store.
Ads
The game is supported by ads provided by Google AdMob. A full-screen ad can only appear after a win, never during a game. No puzzle or game feature depends on watching an ad.
Ads are created by advertisers and delivered by Google's network; we do not choose each ad that appears. That does not remove the responsibilities the law places on us. If an ad seems misleading, offensive or inappropriate, tell support, ideally with a screenshot, and we will take the steps available to us, such as reporting or blocking the ad on the network. The privacy policy explains what data ads involve and the choices you have.
Purchase to remove ads
If you wish, you can make a one-time purchase inside the game that removes all ads. It is not a subscription and there is no recurring charge. The price, with the applicable currency and taxes, is the one the store shows before you confirm.
The purchase is processed by the App Store (Apple) or Google Play under the store's terms, and is tied to the store account used to buy. To use it on another device or after reinstalling the game, sign in to the store with the same account and choose the option to restore the purchase; you do not pay again. A purchase made on one store is not transferred to the other.
Ad removal does not expire: once bought, it applies to the store account used for the purchase, with no further charge. If the purchase is refunded or cancelled, ads appear again. If we ever stop offering the game, we will give at least 30 days' notice on this website; a copy that is already installed does not stop working because of that, and the rights your country's law gives you in that situation are preserved.
Refunds and withdrawal
The store (Apple or Google) sells and charges for the purchase, and the store is the one that returns the money. Ask for a refund where you bought: for Apple, at reportaproblem.apple.com; for Google Play, through your account's order history or Google Play Help. We have no access to your payment details.
If you live in Brazil, you can withdraw from the purchase within 7 days of the purchase date, without giving a reason, and get back the amount paid (article 49 of the Brazilian Consumer Defence Code). After a refund, ads appear again.
If you live in the European Union, the European Economic Area or the United Kingdom, the law generally gives you 14 days to withdraw from a distance purchase. For digital content, that right can end when delivery starts, if you agreed to immediate delivery and acknowledged this consequence at the time of purchase; the store presents and records that condition. You also have the legal guarantee if the digital content is faulty.
If the store refuses a request that the law entitles you to, email contato@bybnd.com.br with the order number or the store receipt. We confirm receipt and reply within 5 days. On Google Play, we can authorise the refund through the store ourselves. On Apple, only Apple can return the amount to the original payment method; in that case we support your request and, if your right is still not met, we return the amount by another method agreed with you.
Nothing here limits withdrawal, refund or guarantee rights that the law of your country gives you.
Using the app and its materials
For as long as you comply with these terms, byBnD grants you a personal, free, non-exclusive and non-transferable licence to install and use the game, for non-commercial purposes, on compatible devices linked to your store account. The game is licensed, not sold: buying ad removal does not transfer ownership of the software. On Apple devices, Apple's standard licence for apps (Licensed Application End User License Agreement) also applies. On Android devices, these terms are the game's licence, alongside the Google Play terms.
You may not sell, rent, sublicense or redistribute the game, present it as your own, remove authorship notices, circumvent the purchase, or copy, modify or reverse engineer it beyond what the law or open-source licences allow. If you seriously breach these terms, the licence may be ended, without affecting the rights the law gives you.
Sudoku is the common name of this type of puzzle and is not our trademark. The byBnD name and logo, the icon, artwork, text and code of the game belong to BYBND INFORMÁTICA LTDA or to those who licensed them to it, and are protected by copyright, software and trademark law. Open-source components retain their own licences; these terms do not remove permissions or exceptions granted by those licences or by law.
Progress and device storage
Progress, preferences, recent wins and statistics are stored on your device. History keeps up to the latest 200 completed games outside training mode. There is no synchronisation or transfer service between devices.
Clearing app data, uninstalling, changing devices, storage problems or changes to the device may cause loss of progress. We do not hold a server copy from which to restore a lost game. This explanation does not exclude responsibility or remedies that mandatory law provides for a defect.
Children and young people
The game is made for a general audience aged 13 and over and is not directed to children: anyone under 13 should not use it. Young people aged 13 to 17 may play with the knowledge and permission of a parent or legal guardian. The game has no chat, public profiles, user uploads, randomised items or gambling.
The in-game purchase must be made by someone aged 18 or older, or with the permission of a parent or legal guardian. The stores offer controls that let parents approve or block purchases (Ask to Buy on Apple; purchase approvals in Family Link on Google Play). If a minor bought without permission, the parent or guardian can ask the store for a refund and write to us; we help as described in the refunds section.
The game does not ask for your age and does not receive age information from the store or the device, so it treats every player in the same way: ads, when shown, are only non-personalised and limited to content suitable for all audiences, usage measurement happens only with permission, and the purchase to remove ads follows the store's rules and the parental controls described above.
For support concerning a child or young person, a parent or guardian should contact us and avoid sending unnecessary identifying information. These conditions do not transfer the provider’s own legal duties of protection to the family.
Support, reports and privacy
For questions or a problem, email contato@bybnd.com.br. Describe the app version, device model and the steps that led to the issue. Do not send passwords, payment-card details or unrelated personal information. You do not need to email us or create an account to play.
The byBnD Games privacy policy, available from this website’s privacy link, explains the data that stays on your device, ads, usage measurement, the purchase, support messages and technical information involved in website delivery. Store and operating-system services also have their own terms and notices.
To report potentially criminal or unlawful content on this website, email contato@bybnd.com.br. Identify yourself, provide a reply contact, identify the page or content and explain the concern; if acting for someone else, explain your authority. Do not attach unlawful material or unnecessary sensitive information. We confirm receipt, assess the notice and communicate the action or decision to retain the content, with reasons and a way to request review by replying. If a review changes the decision, we communicate the revised outcome to the affected parties as applicable.
We keep a private record of notices and their handling and publish annual aggregate transparency information about notices, decisions and any applicable advertising or paid promotion, without exposing personal information. We periodically review these procedures. The portal does not host user uploads or offer paid promotion; procedures address the activities that actually exist and do not promise moderation of a third-party content platform.
Updates and availability
We may release corrections, security updates and changes to the supported versions. Material changes will be described through appropriate app, store or website information. New paid features require a separate purchase; these terms do not authorise an automatic charge.
We do not promise that every future device or operating system will be supported, that access will never be interrupted or that a particular development timetable will be met. Any change or discontinuation remains subject to mandatory notice, support, refund and other rights that apply in your country. Stopping use does not remove rights concerning an earlier defect.
Our responsibility
We take care that the game works as described and we are responsible for defects and for damage we cause, as the law provides. We do not control the store, the device, the operating system or the connection, and we are not responsible for failures that come only from them, unless the law makes us responsible.
For consumers in Brazil and in any country whose law does not allow liability towards consumers to be limited, nothing in these terms excludes or reduces that liability. In other countries, and only as far as local law allows, our total liability relating to the game is limited to the greater of the amount you paid for the in-game purchase and US$ 50, and does not cover indirect damage. This limit does not apply to intent, gross negligence, death or personal injury.
Governing law, courts and complaints
Nothing in these terms excludes mandatory consumer guarantees, rights concerning defective digital products or services, privacy rights, access to regulators or courts, or any responsibility that cannot lawfully be excluded.
If you live in Brazil, these terms are governed by Brazilian law and you may bring a claim in the courts of your place of residence. If you live in another country, these terms are also governed by Brazilian law, but that does not deprive you of the protection of the mandatory consumer rules of the country where you live, and you may use the courts and authorities of that country. We do not require arbitration or a waiver of collective actions.
You can contact us at contato@bybnd.com.br before taking any step; that is an option, not a condition for exercising a legal right. In Brazil, you can also go to the Procon consumer agency of your city or state.
Changes to these terms
The date at the top identifies the version in force. We may change these terms when the game, the law or the store rules change. Changes that affect your rights or obligations are announced on this website and, where possible, in the game or on the store page, at least 30 days in advance. Wording corrections, changes required by law and changes that only benefit you may apply immediately.
A new version does not remove rights you already hold or change a purchase already completed. If you do not agree with a change, you can stop using the game; the ad removal you bought continues to apply. Earlier versions are available from support on request.
These terms are available in English, Portuguese and Spanish. For people who live in Brazil, the Portuguese version applies; in other countries, the English version applies. A difference between the versions is read in the way most favourable to the consumer and does not reduce mandatory rights.
