Privacy policy

Notebook Duel · Effective from: 2026-09-17

This policy explains what data is processed when you use the Android game Notebook Duel.

Data stored on your device

The game stores sound, haptic-feedback, optional line-highlight, and optional analytics preferences on your device. Unity Authentication may also store an anonymous session token required only for online play. These values remain until you clear the app's data or uninstall it.

Advertising and consent

Offline modes may show a Google AdMob interstitial only at a natural break between completed rounds. The game uses Google's User Messaging Platform (UMP) to request consent or present privacy choices where required. A privacy-policy link is always available in Settings, and UMP privacy options are shown there when required.

Depending on your region, consent choices, device settings, and the ad-serving mode, Google Mobile Ads may process and share data such as:

  • IP address, which may be used to estimate general location;
  • app interactions and advertising interactions;
  • diagnostic information;
  • device and account identifiers, including the Android advertising ID when it is available and permitted; and
  • information used to prevent fraud, provide, measure, and personalize ads.

Google's privacy policy is available at https://policies.google.com/privacy. Google's Mobile Ads data disclosure is available at https://developers.google.com/admob/android/privacy/play-data-disclosure.

Diagnostics and optional analytics

The game uses Unity Diagnostics to receive crash reports, unhandled exception reports, Application Not Responding reports, and related technical context such as the app version, device model, operating system, and the broad game phase in which a problem occurred. Diagnostic metadata does not contain player names, room phrases, Unity Player IDs, board coordinates, or complete board states.

In versions offering optional Unity Analytics, it is off by default. You may enable it separately in Settings. Only if enabled, Unity processes an installation-specific identifier, IP address, session and device information, and these game events:

  • rounds started, completed, or abandoned;
  • game mode, board type, board size, and required line length;
  • result, move count, and bucketed round duration;
  • online host/join success, bucketed connection duration, and rematch requests; and
  • interstitial impressions.

The analytics setting is separate from Google UMP advertising choices. Turning analytics off stops collection and asks the Unity Analytics SDK to delete the analytics data associated with that installation. Analytics events never contain player names, room phrases, Unity Player IDs, individual moves, board coordinates, or complete board states. Identifiers and technical data may still allow events to be linked to an installation; we therefore do not treat the entire dataset as fully anonymous.

Online play and Unity Gaming Services

Local and AI play do not require online services. When you choose online play, the app automatically creates a technical anonymous Unity Authentication session and uses Multiplayer Services (Lobby/Relay), Cloud Code, and Cloud Save. The game provides no accounts, sign-in UI, profiles, player names, leaderboards, or identity recovery.

The following data may be processed to provide online play:

  • IP address;
  • a random anonymous Unity Authentication Player ID and session tokens;
  • the room phrase you enter;
  • session identifiers, Relay join codes, connection state, and timestamps;
  • moves, board state, rematch choices, and related synchronization data sent during the session; and
  • technical service logs needed for security, reliability, and troubleshooting.

The room registry stores a normalized room phrase, the host's anonymous Player ID, a hashed reservation token, room state, a Unity join code, and timestamps. The game does not request your real name, email address, phone number, contacts, precise location, photos, microphone access or recordings, or payment details.

Why data is processed

Data is processed to provide advertising according to applicable choices; to create an anonymous online session; reserve and resolve private room phrases; connect players and synchronize matches; support rematches and reconnection; and protect, diagnose, and operate the app and its services.

Where the GDPR applies, providing chosen online features is based on performance of a contract (Article 6(1)(b)). Optional analytics and advertising operations requiring consent are based on consent (point (a)). Security, necessary diagnostics and correspondence rely on our legitimate interest in maintaining and protecting the service and responding to requests (point (f)); legal obligations rely on point (c). Consent is obtained separately where required by law.

Service providers and sharing

Google and its partners process advertising data as described above. Unity Technologies and its service providers process diagnostics, optional analytics, and online-play data on our behalf. We do not sell personal data ourselves.

Unity's player privacy information is available at https://unity.com/legal/game-player-and-app-user-privacy-policy.

Retention

  • Local preferences remain until app data is cleared or the app is uninstalled.
  • Pending room reservations expire after approximately 2 minutes.
  • Active room reservations expire after approximately 70 minutes without renewal; closed reservations expire after approximately 60 minutes and are removed during later maintenance.
  • Google and Unity retain identifiers and service logs according to their own product policies and legal obligations. Cloud Save records remain until they are removed by the developer or service process.
  • Unity Analytics currently retains personal data for up to 13 months by default, unless deletion is requested or a shorter service setting applies.

Data access and deletion

You may request information about or deletion of technical data associated with an anonymous online session by contacting developer@kolenda.dev. Because the game collects no real-world identity or player name, locating the correct record may require the anonymous Player ID or technical installation details.

Clearing or reinstalling the app may create a new anonymous Player ID and does not by itself guarantee deletion of data already held by an online or advertising service. Google privacy and ad controls are also available through your Google account, Android device settings, and the in-app UMP privacy entry when it is required. Optional analytics can be disabled in Settings; doing so also submits an analytics deletion request for the current installation.

Children

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.

The game does not knowingly ask users to provide contact details or a real-world identity. If you believe a child has entered personal data in a room phrase or another field, contact us so we can investigate and delete it.

Your rights

Where provided by the GDPR, you may request access, rectification, erasure, restriction and data portability. You may object to processing based on legitimate interests and withdraw consent without affecting the lawfulness of earlier processing. You may complain to a supervisory authority; in Poland this is the President of the Personal Data Protection Office: https://uodo.gov.pl.

Using a technical anonymous session is required only for the online mode you choose. Declining optional analytics does not block any game mode. We do not make solely automated decisions producing legal or similarly significant effects on you.

The data deletion page describes the removal request process.

This website and email contact

This information website itself contains no ads, analytics, external fonts or tracking scripts, and sets no cookies or browser storage. Its assets are served from its own domain.

The hosting server may log IP addresses, request dates, visited paths, response status and browser details to deliver and secure the website. These logs are processed by the hosting provider and retained according to its configuration, only as long as needed for these purposes. Contact the controller for the specific retention period.

If you email us, we process your email address and message to respond and handle the matter. Correspondence is kept while handling the matter and longer only as needed for legal obligations or establishing, exercising or defending legal claims. Hosting and email providers may process this data to supply their services.

Security and international processing

Online data is encrypted in transit. Google and Unity may process data outside the European Economic Area. Required transfer safeguards may include an adequacy decision or standard contractual clauses, depending on the provider and processing location. Contact the controller or consult the provider documents linked above for details of applicable safeguards and how to obtain a copy. No internet service can be guaranteed to be completely secure.

Changes

We may update this policy when the game, legal requirements, or service providers change. The effective date will be updated when a revision is published.
