UNO – Multiplayer Card Game

Last updated: 1 July 2026 · Effective immediately.

1. Overview

This Privacy Policy explains how UNO – Multiplayer Card Game ("we", "our", "the app") handles your information. We have built the app to be privacy-friendly by default: we do not collect personal data from you to play the game.

By installing or using the app you agree to the practices described below. If you do not agree, please uninstall the app.

Personal data collected

None

Account required

Third-party SDKs

Ads only

Data encrypted in transit

Yes (HTTPS / TLS)

2. Information We Collect

2.1 Information you provide

The app does not require an account, email, phone number, or any other personal identifier to play. You may optionally enter a nickname/avatar for display in multiplayer rooms, but this information never leaves your device.

2.2 Information collected automatically

No usage analytics or crash logs are collected by the app.
No advertising identifiers are read or shared with us.

2.3 Information stored locally on your device

Your in-game preferences (sound, last avatar).
The deck state during an active single-player match.

You can erase all locally stored data at any time by clearing the app's data in your device's system settings.

3. Third-Party Services

The app uses a small number of third-party services to operate. Each is documented below.

3.1 Google Mobile Ads (AdMob)

We display banner, interstitial, and rewarded video ads through Google Mobile Ads SDK. To deliver and measure these ads, Google's SDK may receive the following on your device:

Device advertising identifier (IDFA / GAID)
Coarse location (country / region, not GPS)
Device model and OS version
Ad interaction events (impressions, clicks)

You can opt out of personalized ads at any time via your device's Settings → Privacy → Ads. Google does not share this data with us.

See Google's privacy practices here: policies.google.com/privacy.

3.2 Firebase (optional multiplayer backend)

Multiplayer rooms can optionally be synchronized through Firebase Firestore. If you choose to host or join a multiplayer match, the room's pseudo-random room code, your self-chosen nickname, and the in-game state are stored in Firebase while the room is open. The data is removed automatically when the room closes.

Firebase is governed by Google's Firebase Privacy notice.

4. Children's Privacy (COPPA / GDPR-K)

The app is designed to be safe for players of all ages, including children under 13 (COPPA) and under 16 (GDPR-K). We:

Never collect personal information from any user.
Configure all third-party ad SDKs to serve child-directed / non-personalized ads by default.
Do not include social features, chat, or third-party login.

Parents who wish to limit ad personalization entirely can reset the device's advertising ID from system settings or enable device-wide restricted ad tracking.

5. Your Rights

Depending on your jurisdiction, you may have the right to:

Request access to any personal data we hold about you (we hold none).
Request deletion of any personal data we hold about you (we hold none).
Opt out of personalized advertising.
Withdraw consent and uninstall the app at any time.

Since we do not collect personal data, there is generally no further action for us to take. If you have a specific request, please contact us at factictionary@gmail.com.

6. Data Retention

In-game state: kept only while a multiplayer room is open; deleted automatically when the room closes.
Local preferences: kept until you clear the app's data.
Ad data: governed by Google's retention policies.

7. International Data Transfers

Because we do not collect personal data, there are no cross-border transfers of personal data to disclose. Third-party services (Google) may transfer data across borders as part of their normal operation; their policies apply to those transfers.

8. Security

We use industry-standard HTTPS / TLS for all network traffic. The app does not transmit unencrypted personal data because it does not collect any. Local data is stored using the device's standard secure storage APIs.

9. Changes to This Policy

We may update this policy from time to time. We will post the updated version here and update the "Last updated" date at the top. Material changes will be highlighted inside the app for at least 30 days before they take effect.
