Terms of use

About the game

Notebook Duel is an Android game. For support, issues and complaints, contact developer@kolenda.dev. These terms cover the game and its online features.

Using the game

You may use your supplied copy of the game for personal play. Rights to the game and its materials remain with their respective owners. These terms do not restrict rights granted by mandatory law or licences for third-party components.

The game requires a compatible Android device. Online features require an internet connection; your network provider may charge for data. Check the download source for version availability and device requirements.

The game is intended for people aged 13 and over and is not directed to children under 13. If you are a minor, involve a parent or guardian to the extent required by the laws of your country.

Anonymous online play

Local and AI modes do not require online services. Online play automatically uses a technical anonymous Unity identifier, without an account, profile, player name, leaderboard, or visible sign-in.

A private room phrase identifies a match. Share it only with the person you want to play with, and do not include personal information or a password used for another service.

Fair play

• Do not manipulate results or game communications to cheat.
• Do not disrupt services or attempt to access someone else's session or data.
• Do not put unlawful content or personal information in a room phrase.

If these rules are breached, we may restrict online access to the extent necessary to protect players and the service. Contact the provider to raise concerns or request a review.

Advertising and privacy

The game may display ads between completed offline rounds. Advertising privacy choices are available according to Google UMP settings. Optional analytics has a separate in-game setting.

The privacy policy explains data processing, service providers and your rights. Using the game does not replace consent where consent is required.

Availability and updates

Online connections may be interrupted by outages, maintenance or service providers. We cannot guarantee uninterrupted availability or that a match interrupted before confirmation will have its result recorded.

Updates may fix issues and change features; online services may require a current version of the game. These provisions do not exclude statutory rights, including consumer rights concerning the conformity of digital content or services.

Support, complaints and leaving

Contact developer@kolenda.dev with a description of the issue and, where relevant, your game version and device model. Do not send passwords, tokens or payment details. We will respond without undue delay and within any applicable legal deadline.

You can stop using the game at any time. Uninstalling does not automatically remove data already processed by service providers. The data deletion page explains how to request removal.

Changes to these terms

Changes may be needed when game features, services or legal requirements change. We will publish a revised version with its effective date. Material changes affecting existing users will be communicated appropriately as required by law. Changes do not remove previously acquired rights.
