Let’s get right to the important part: Luyện Ngục does not collect any personally identifiable information.
I use data collected from Luyện Ngục’s players to do things such as fix bugs, improve game mechanics, and measure audience size. None of these purposes require any of your personal data, or for me to track you in any way.
You can opt-out of all data collection the game performs via the game’s settings screen. Note that data collection is only present in the Google Play and App Store versions of Luyện Ngục.
Feel free to read on if you want more specific details about what data I collect, and how it is used.
Key Terms and Entities
Luyện Ngục, which is developed by Lãng Khách, based by Pixel Dungeon & Luyện Ngục Dungeon. This policy applies to the Google Play and App Store versions of Luyện Ngục; other versions do not collect any data.
Luyện Ngục can be contacted via email if you have any questions about this policy: email@example.com.
Firebase refers to the Firebase family of services offered by Google LLC. Google is the data processor for all data collected via Firebase, and I am the data controller. For more information on Google’s role as data processor, including data security and storage duration, consult Google’s Firebase Privacy and Security Information. Luyen Nguc uses the ‘Google Analytics for Firebase’ and ‘Crashlytics’ services, has disabled all features which collect personal information, and has set user-level data retention at 180 days.
Data Collection and Use
Luyện Ngục does not collect any personally identifiable information. We uses Firebase to collect a variety of data relating to gameplay activity, but no data which could be used to identify individual players. Firebase does include functionality to collect tracking IDs and similar personally identifiable data, but this functionality is unused or disabled in Luyen Nguc.
You may opt-out of data collection via Firebase at any time by disabling “share gameplay data” in Luyện Ngục’s settings menu. Opting out disables all the data collection described below.
Luyện Ngục includes the Firebase SDK in its code, which collects and reports information whenever an ‘event’ occurs. Events are points within user interaction or gameplay that are of interest to Luyện Ngục. Luyện Ngục receives data from the following events:
- A game session starts, continues, or ends.
- The player dies within the game, or completes the game.
- The player defeats a boss within the game.
- The game crashes, or encounters an internal error.
- The game is uninstalled, updates, or its data is cleared.
- An in-app-purchase is made or refunded.
- The device the game is installed on is updated.
When an event is triggered, the following data may be recorded and transmitted via Firebase:
What Data is Collected & How it is Used
e.g. crash details, cause of player death, etc.
This data is needed to provide context or detail for the event being recorded. Without this data the event is meaningless. For example, a crash event requires information about the crash to be useful.
Data relating to the player character, game items, etc.
This data is used to make game design decisions relating to the performance and popularity of various game elements. For example, the success rate of the game’s playable characters can be found by using player character information over all the different game end events.
Selected options from the game’s settings menu.
This data is used to determine how often players choose various game settings options. For example, I can plan future additions or changes to the settings menu based on the popularity of existing settings.
Game version, platform, and installation source.
This data is used to determine which version of Luyện Ngục an event comes from, and where the game was acquired. For example, this data is used to detect if an event is from an old version of Luyện Ngục and is therefore no longer relevant.
Device model, OS version, language, and timezone.
This data is used to produce statistical information about what devices play Luyện Ngục, and to contextualize certain events. For example a particular crash may only occur on one type of device, or one OS version.
Location data based on anonymized IP address.
This data is used to produce statistical information about the general location of Luyện Ngục’s playerbase. For example, I can track the game’s popularity in one country versus another.
IP address information is anonymized before it is transmitted.
A unique ID randomly generated when the game is first played
This data is used to connect events that come from the same instance of Luyện Ngục. For example, the instance ID can be used to tell the difference between 1 instance of the game crashing 10 times, or 10 crashes from 10 different instances.
This is not a tracking ID! It can only be used to group events together, not to tell what specific user or device they came from.
I do not share this data with any third parties. However, I do occasionally share aggregated data with the public if it relates to an announcement or blog post. An example of this sort of data sharing is this figure, which was shared in this blog post, to illustrate that the Rogue was significantly weaker than other characters in the early stages of the game.
