Privacy policy
Last updated: October 16, 2026
Djeuns Cards is a collectible card game for mobile, published by Narfedome. The game is free and funded by advertising. This page explains what the app does with data about you and your device, what stays on your phone, what is shared, and with whom.
In short
- No account, no sign-in: we never ask for your name, email address or password.
- Your collection, progress and settings stay on your phone. We run no game server.
- Ads are provided by partner ad networks (Unity LevelPlay and Unity Ads), which collect some device data to show and measure ads.
- Ads are only personalised if you agree, and you can change your mind at any time in the game settings.
Data stored on your device
The game saves locally, on your phone: your card collection and its variants, your showcase, your energy and progress, your interface style, your sound settings and your choice about personalised ads. This data is not sent to Narfedome and does not leave your device (apart from Android's system backup, if you turned it on). Uninstalling the app deletes it.
Data collected by ad networks
To show ads (rewarded videos you choose to watch to earn energy or a perk, and ads between two actions), the game includes the Unity LevelPlay SDK and the Unity Ads network, provided by Unity Technologies. When an ad is requested or shown, these partners may collect:
| Data | Purpose |
|---|---|
| Android advertising ID (when available) | Limit repeated ads, measure their results and, if you agree, personalise them |
| Device information: model, operating system, language, settings, carrier and connection type | Pick a compatible ad and display it correctly |
| IP address and the approximate location derived from it (country, city) | Serve ads suited to your region, comply with local rules, prevent fraud |
| Interactions with ads (impression, click, video watched to the end) | Grant the reward, measure performance, prevent fraud |
| Technical crash data from the ad components | Diagnostics and stability |
This data is processed by Unity Technologies and, depending on the ad shown, by the advertisers and ad networks working with Unity. Their processing is described in Unity's privacy policy for game players and app users. Narfedome only receives aggregate statistics from these partners (number of ads shown, revenue), never data that identifies you.
Your consent
On first launch, the game asks whether you agree that ad partners use your data to show you ads tailored to your interests. If you decline, you will see non-personalised ads just as often: the game stays fully playable. You can change this choice at any time in the game: Réglages › Publicités › Pubs personnalisées (Settings › Ads › Personalised ads).
You can also reset or delete your advertising ID in Android's settings (Settings › Privacy › Ads, depending on the device).
Purchases
If the "Sans pub" (no ads) purchase is offered in the game, payment is handled entirely by Google Play. Narfedome never receives your payment details: only the confirmation that the purchase took place.
Age of players
Djeuns Cards is meant for players aged 13 and over. The game is not designed for children under 13 and does not knowingly collect data about them.
Your rights
Depending on where you live (in particular in the European Union, under the GDPR), you have rights of access, rectification, erasure, objection and withdrawal of consent. Since Narfedome holds no data that identifies you, requests about advertising data are handled by Unity, through its privacy policy above. You can also write to us and we will help you exercise your rights. You may lodge a complaint with your country's data protection authority (in France, the CNIL).
Security and retention
Game data stays on your device for as long as the app is installed. Exchanges with ad partners are encrypted (HTTPS). Retention of advertising data is set by Unity and described in its privacy policy.

For any question about this policy or your data, write to narfedome.support@gmail.com.
Changes to this policy
If the game changes (new ad partner, online feature, purchases…), this page will be updated before the release of the version concerned, with a new date at the top.
