Scope and who is responsible
This policy covers games.bybnd.com.br and its support service. The Sudoku byBnD section describes its current offline edition. Statements about that edition do not automatically apply to other games or future online features. Opening the website or contacting support is separate from playing offline.
BYBND INFORMÁTICA LTDA, CNPJ 32.574.894/0001-10, at Alameda dos Maracatins, 1435 - Conjunto 307 - Indianópolis, São Paulo - SP, 04089-015, Brazil, is the publisher and the controller for the website and support information we process for the purposes described here.
For support and general enquiries, contact contato@bybnd.com.br. Our data protection officer (DPO) is Robson Felippelli Vicente; privacy questions and rights requests can be sent directly to dpo@bybnd.com.br. You can play without giving us your name, email address or other contact details.
This notice complements our corporate privacy policy at https://bybnd.com.br/privacidade (Portuguese; English summary at https://bybnd.com.br/en/privacy). The specific game and portal practices are explained below. The institutional website has separate analytics choices; playing Sudoku offline does not activate them.
Sudoku byBnD: information in the offline game
The game processes entered numbers, pencil notes, undo history, progress, completed puzzles, active playing time, preferences, language and recent results on your device. This lets you continue a puzzle and see local history and statistics. History contains up to the latest 200 recorded wins outside training mode.
The current app does not send this information to us. It has no account, login, backend or cloud save, and no advertising, purchases, analytics, crash-reporting or push-notification SDKs. It does not request contacts or location or create a player or installation identifier for us.
Local storage and deleting progress
Progress is kept in the app's private storage. Its integrity checks help detect damaged save files; they are not encryption or a cloud backup. Records are replaced during normal play, and older wins leave the history when its limit is reached.
The app is configured to exclude its saves from operating-system backup and transfer. Actual device and restore behaviour can vary. Clearing app data or uninstalling may permanently remove progress. We do not hold a server copy, cannot restore a lost game and cannot access or delete local files remotely. There is no account to close.
Support and information you send
If you contact us, we receive your email address, message and any details or attachments you choose to include, such as the app version, device model, system version or a screenshot. If a store makes feedback you send to us available, the relevant name or handle and message may also be received. We use this information to reply, investigate the issue and handle privacy requests.
Providing information is voluntary, but we may need a reply address and enough context to answer. Send only what is necessary; do not send passwords, keys, payment-card details, identity documents or unrelated sensitive information unless a specific lawful need has been explained. We do not use support messages for advertising.
Website requests and cookies
The website is delivered through Cloudflare. Technical request information, including IP address, browser information, requested page and request time, is processed to deliver pages and protect the service against abuse. Visiting these pages does not upload your saved game.
The portal's code adds no advertising trackers or analytics SDKs and does not set cookies or use browser storage. Cloudflare security features may set technical cookies when those features are needed and enabled. Browser settings can restrict cookies, which may affect security checks. Any optional tracking would require its own review, disclosure and any legally required choice before activation.
Purposes and legal grounds
Where a legal basis is required, support relating to a service you requested is handled to provide that service; other enquiries are handled for our legitimate interest in responding. Website delivery and proportionate abuse prevention serve our legitimate interests in operating and protecting the service. Mandatory privacy requests and legally required records are handled to comply with applicable law. Legitimate-interest processing must respect your rights and reasonable expectations.
These grounds are applied according to the circumstances and the laws that govern the processing, including Brazil's LGPD and the GDPR where applicable. Reading this policy or using the website is not consent to advertising or other optional processing. The current app and portal do not create advertising profiles or make automated decisions producing legal or similarly significant effects.
Recipients, platforms and international processing
Corporate email is operated through Google Workspace, as described in our corporate privacy policy. Access to support information is limited to those handling it and the providers needed to deliver and store email. Cloudflare processes website data under its applicable service terms; its privacy notice distinguishes processing on customers’ behalf from certain processing for its own network purposes. Stores and operating systems also process information under their own notices and settings. We do not sell personal information or share it for cross-context behavioural advertising.
Hosting and email services may process information outside your country, including Brazil, the United States and countries in Europe or elsewhere in the providers' networks. International processing is subject to the transfer rules applicable to the data concerned. Cloudflare describes its arrangements at https://www.cloudflare.com/privacypolicy/ and https://www.cloudflare.com/cloudflare-customer-dpa/; Google provides its data-processing terms at https://workspace.google.com/terms/dpa_terms.html. Contact us for information on the destination countries, applicable safeguards and copies or further details where available. Provider notices do not replace our responsibility for our processing.
How long information is kept
Local game information follows the storage and history limits above. Support information is kept only for the time needed to handle the request, investigate and document its resolution, or meet an applicable legal requirement. We review information we control for continuing need and delete or anonymise it when there is no longer a valid purpose for keeping it.
Website technical records follow the security purposes, service settings and applicable legal retention duties. A justified legal hold or a requirement to keep evidence may change the period for the affected record. We do not promise one fixed period for every type of information or that disabling an application log removes all provider security records. You can ask us about the criteria and retention applicable to your information.
Your choices and privacy rights
You control local game data through the device and its app-storage options. For information we hold, write to our DPO at dpo@bybnd.com.br; requests received through contato@bybnd.com.br are directed to the appropriate person. Depending on applicable law, you may request confirmation and access, correction, deletion or anonymisation, restriction, objection, portability, information about recipients and withdrawal of consent where consent is used. We assess requests under the law that applies; some rights have conditions and lawful exceptions.
We handle requests within the applicable legal deadlines and without a fee where the law requires. We may ask for limited information reasonably needed to locate a record or verify that it concerns you; we cannot identify a local save from your email address. We explain any lawful refusal or information that must be retained. You may complain to the competent data-protection authority, including the ANPD in Brazil or the relevant EEA or UK authority where applicable, and seek other available remedies.
Children and young people
The offline game has no chat, public profile, account or personalised advertising. It does not ask players to provide their name, date of birth or contact details. We do not use children's information for advertising. A store age rating describes content suitability; it is not permission to process a child’s personal information.
A parent or legal guardian who needs help or wants to raise a privacy concern about a child can contact us. Please avoid sending identifying information about a child that is unnecessary to explain the issue. If we receive unnecessary personal information about a child, we restrict or remove it as appropriate, subject to applicable protection and legal requirements.
Security and changes to this policy
We use safeguards appropriate to the processing, including private app storage, secure website delivery and limiting access to support information. Save-file integrity checks do not make those files encrypted, and no system can guarantee absolute security. Report a suspected privacy or security problem to dpo@bybnd.com.br or contato@bybnd.com.br without sending credentials or unnecessary personal information.
New advertising, purchases, online services, additional measurement or material changes to data handling require a new review of the build, providers, notices and any required consent before activation. We update the date above and provide further notice where required. A future policy change does not itself supply consent or permit processing that the law prohibits.
