Privacy Policy

The app «Durak Online & Offline Cards» (package ru.durak.app, developer NT Vibe Studios / NTSAUTOSIGA LLC). Last updated: October 2, 2026. Русская версия

What data we process

• An anonymous account identifier. On first launch an anonymous Firebase Authentication (Google) account is created. It contains no name, e-mail, phone number or password and is used only for online play and the leaderboard.
• The nickname and avatar you choose yourself. Other players see them on the leaderboard and at the online table.
• Online game statistics: rating, games played and won, points, winning streak, moves in online games. Stored in Firebase Cloud Firestore (Google).
• Anonymous analytics (Firebase Analytics): events such as «game started» and «game finished», device model and Android version — not linked to your identity.
• Crash reports (the Tracer service by VK LLC): if the app crashes or freezes, a technical record is sent — where in the code the error happened, device model, OS and app version. It contains no name, nickname or game content.

Microphone and voice at the online table

• Microphone permission is requested when you sit down at an online table, not at launch. Declining breaks nothing: the game simply goes on in silence.
• Voice can be switched off entirely in Settings («Voice at the online table»). The microphone is then never turned on.
• The conversation is not recorded or stored — neither on the device nor on our servers. Speech is encrypted between the players' devices (DTLS-SRTP) and passes through our relay server, which sees only the encrypted stream and stores nothing. The relay is used on purpose, so that players do not see each other's IP addresses.
• There is no speech recognition, transcription or analysis of what is said.
• The microphone works only while an online game is running and the app is open.

Camera and the face circle

• The camera is off by default and is turned on with a separate button at the online table. Permission is requested when you press that button. Declining breaks nothing.
• Turning it off really stops the camera; sending the app to the background also turns it off.
• Video is not recorded or stored — neither on the device nor on our servers. Frames are encrypted between the players' devices (DTLS-SRTP) and pass through our relay server, which stores nothing.
• There is no face recognition or image analysis.
• Any opponent can be hidden: one button removes both their sound and their picture on your screen.

Reports about an opponent

If you report an opponent, we store the fact of the report: who reported whom, in which match and when. This is needed to restrict the microphone of a player reported by three different people; the restriction is lifted automatically after a week. The content of the conversation is not stored. You can also hide an opponent locally and ask never to be matched with them again; that list is visible only to the server.

What we do not collect

We do not request or store your name, e-mail, phone number, contacts, location, photos or payment details. Payment details are handled by the app store and never reach us.

Advertising

The RuStore and App Store versions contain no ads.

The Google Play version has one kind of advertising — a video you start yourself with the «Try it for a day» button in the Collection. There are no banners and no ads between games; until you press that button the ad service is not contacted.

• The videos are served by Google AdMob. To select and count ads it receives the device advertising ID, device information and an approximate region derived from the IP address — see how Google uses data.
• Where the law requires it (EEA, UK, Switzerland), a consent window is shown before the first video. Without consent the video may not be shown; this does not affect the game.
• You can reset or delete the advertising ID in Android settings: Privacy → Ads.

Purchases

«Full Collection» is a one-time purchase made through Google Play or the App Store. The store processes the payment; we receive only the fact of the purchase in order to unlock the collection, and see neither the card nor the payer's name.

Local data

Settings, the saved game, achievements and story progress are stored only on your device and are removed together with the app.

Sharing with third parties

Data is processed by Google Firebase services (Authentication, Cloud Firestore, Cloud Functions, Analytics) under the Firebase privacy policy, by the Tracer crash-reporting service and, in the Google Play version, by Google AdMob (see «Advertising»). Data is not sold.

Deleting your data and account

Uninstalling the app removes all local data. To delete your online profile (anonymous account, nickname, rating, statistics), e-mail tsyrenovnik@gmail.com with your nickname; the profile is deleted within 14 days.

Children

The app is not directed at children under 13 and does not knowingly collect their personal data.

Changes

When this policy changes, the new version is published at this address with an updated date.
