1. General provisions

This policy sets out how the personal data of users of the Duelio Backgammon app and its website nardy.duelio-game.com (together, the Service) is processed and protected in accordance with Federal Law No. 152-FZ of 27.07.2006 "On Personal Data".

The personal data operator is the owner of the Service, an individual applying the special tax regime "Tax on Professional Income" (self-employed), taxpayer identification number (INN) 166017443612 (hereinafter, the Operator). The Operator can be contacted on matters of personal data processing at the email address support@duelio-game.com.

By using the Service and registering in it, the User confirms that they have read this policy. The User gives consent to the processing of personal data by ticking the corresponding box in the registration form.

2. What data is processed

email address — at registration;
password — stored only as an irreversible hash; the Operator does not know the password;
nickname (in-game name) — you can choose it yourself; otherwise it is made from your email address;
technical identifier of a guest account — if the user plays without registration;
game data: games played (opponents, result, score, rating change), rating in each game, number of wins and losses;
game log — to find and fix bugs in the game: the game number, moves and dice rolls with their timing, the result, the app version, the device model and a random app installation number. The log contains no name, email or account ID; a game against the computer, two players on one phone or Nearby is sent from the app to the server when a connection is available;
settings: language, sound, hints, chosen board;
support requests: the text of the message, the email address for the reply, screenshots attached by the user and, if the user ticked "Attach device information", device information (model, system and app version, game mode);
technical data: IP address, browser and device information, date and time of requests, cookies.

The Service does not request or process special categories of personal data.

3. Purposes of processing

registration and signing in to the account;
operation of the Service: games against the computer and other users, rooms by code and by link, saving games and rating, settings and boards;
showing the nickname and rating to other users — opponents in a game and in rating tables;
replies to the user's inquiries and fixing errors the user reported;
finding and fixing bugs in the game using game logs;
security of the Service: protection against hacking, password guessing, automated registrations and abuse.

The Service does not send advertising mailings.

4. Legal grounds

Processing is carried out on the basis of the user's consent (clause 1, part 1, Article 6 of Federal Law No. 152-FZ) and for the performance of the agreement with the user (clause 5, part 1, Article 6 of Federal Law No. 152-FZ).

If the user is under 14, registration is carried out, and consent to data processing is given, by their parent or other legal representative.

5. How data is processed

The Operator performs the following actions with personal data: collection, recording, systematization, accumulation, storage, clarification, use, depersonalization, blocking, deletion and destruction. Processing is carried out using automated means.

The User’s nickname and rating are visible to their opponents. The email address is not shown to other users.

The Operator does not sell or transfer personal data to third parties, except where this is needed for the Service to work (the hosting provider) and in cases provided for by the laws of the Russian Federation.

The recording, systematization, accumulation, storage, clarification and retrieval of personal data of citizens of the Russian Federation are carried out using databases located on the territory of the Russian Federation.

6. Retention periods

Account data, games and rating are kept while the account exists. The account can be deleted in the app: Settings → Account → Delete account. Deletion is immediate: the email address, password, nickname, rating, settings and support requests are erased, and records of played games are anonymized and remain with opponents under the name "Deleted player". You can also withdraw consent and request deletion of the account by writing to the Operator: the data is deleted within 30 days. Technical logs are kept no longer than needed to keep the Service secure.

Game logs are kept for one year and then deleted.

7. User rights

to obtain information about the processing of their personal data;
to demand that data be clarified, blocked or deleted if it is incomplete, outdated, inaccurate or processed unlawfully;
to withdraw consent to the processing of personal data;
to appeal the Operator's actions to Roskomnadzor or in court.

A request can be sent to support@duelio-game.com. The reply is sent within the period established by Federal Law No. 152-FZ.

8. Cookies and data on the device

The Service uses a cookie without which it does not work: for signing in to the account. In addition, the browser or app stores on the user's device settings, the selected game, statistics and the guest nickname — this data is not transmitted to the Operator until the user signs in to an account. The Service does not use advertising or third-party analytics cookies. Cookies can be disabled in the browser settings, but then sign-in and rating saving will not work.

The Android app requests access to Bluetooth and to nearby Wi-Fi devices only for the "Nearby" mode — a game for two on two phones without the internet: the phones find each other and exchange moves directly, via Google's Nearby Connections service. On Android 12 and earlier versions, the system allows such scanning only together with access to geolocation, so the app requests that as well. The app does not determine, store or transmit to anyone the user's location; the moves of a game in this mode go only between the two phones and do not reach the Operator. The permissions are requested when the user themselves selects the "Nearby" mode, and they can be withdrawn in the phone settings — the other modes work without them.

In the iPhone app, the "Nearby" mode works via Apple’s device-to-device connectivity built into iOS (Multipeer Connectivity) over Bluetooth and Wi-Fi; the app asks for access to the local network and does not ask for location. Game moves travel only between the two devices and do not reach the Operator. Access can be revoked in the iPhone settings (Privacy & Security → Local Network). The app does not use push notifications: reminders are created and shown by the device itself, without sending any data. If the User attaches a screenshot or photo to a support request, the file is sent to the Operator only with that request and is used only to answer it.

The app requests permission for notifications after the first game played. Without it the game works; notifications simply do not arrive. The app may remind the user about itself if they have not opened it for a long time: the phone shows such reminders itself on a schedule, and information about them is not transmitted to anyone. Notifications can be disabled in "Settings" → "Notifications" or in the phone settings.

9. Data protection

The Operator takes legal, organizational and technical measures to protect personal data against unauthorized access, alteration, dissemination and destruction: the connection to the Service is encrypted (HTTPS), passwords are stored as a hash, access to data is restricted, and protection against password guessing is applied.

10. Changes to the policy

The Operator may change this policy. A new version takes effect when published unless it states otherwise. The current version is always available in the app and at nardy.duelio-game.com.
