Site legal information
This policy explains how Sudoku Multiplayer processes the personal data of visitors, registered users, and players.
Last updated
This version applies to the use of Sudoku Multiplayer on the sudoku-multiplayer.onlinedomain and on the routes associated with the service.
1. Controller and contact
The controller of the processing is the operator of Sudoku Multiplayer. For privacy and security reasons, the controller's full identification details are not published directly on this page. If you need those details, want to exercise your rights, or wish to send a legal communication, you can request them by writing to contacto@sudoku-multiplayer.online.
Main service domain: sudoku-multiplayer.online.
2. Data we process
3. Purposes
4. Legal bases
The main legal basis for managing accounts, games, profiles, challenges, rankings, and associated features is performance of the contractual relationship or the application of measures requested before account creation.
For security, abuse prevention, competitive integrity, preservation of technical logs, and reasonable service improvement, the legal basis may be the controller's legitimate interest, always balanced against users' rights.
For marketing communications, non-essential analytics, advertising storage, ad personalization, and similar technologies that require consent, the legal basis will be your consent. You can withdraw it at any time.
Where information must be retained to comply with tax, accounting, contractual, security, or other legal obligations, the legal basis will be compliance with a legal obligation or the applicable legitimate interest.
5. Providers and transfers
To operate the platform, we use technical providers that may process data on behalf of the controller: hosting, database, authentication, transactional email, email marketing, analytics, advertising, payments, billing, taxes, consent management, monitoring, security, and support tools.
Those providers may include Supabase, Vercel, Stripe, Resend, Google Analytics, Google AdSense, Google-certified consent management tools, social login providers such as Google, GitHub, or X, and email marketing providers such as Acumbamail, depending on the feature used.
If any provider involves international transfers of personal data, safeguards recognized by the applicable privacy rules will be applied where required.
6. Retention
We retain your data while you keep an active account or while it is necessary to provide the service, maintain gameplay history, resolve incidents, prevent fraud, or comply with legal obligations.
When you request deletion of your account, data that is no longer necessary will be deleted or anonymized. Some data may remain blocked for the periods required by law or while liabilities may arise.
7. Rights
You can exercise these rights by writing to contacto@sudoku-multiplayer.online. If you need the controller's full contact details for a formal communication, request them through that same channel.
8. Minors, security, and changes
Minors may register and use Sudoku Multiplayer if they have authorization from their parents, guardians, or legal representatives when applicable law requires it. In the United States, COPPA generally requires verifiable parental consent before collecting personal information online from children under 13 where the rule applies. If you live in another country, the age may be different.
We apply reasonable technical and organizational measures to protect personal data. Even so, no internet-connected system can guarantee absolute security.
This policy may be updated when the law, the service, providers, or the way data is processed changes. If the changes are relevant, they will be communicated through reasonable means within the platform.
