This policy explains what information the Hjónakapall card game app uses and why. Questions and requests: hjonakapall@gmail.com.
Playing against the phone
Nothing is sent anywhere. Your game in progress, statistics and settings (language, sound) are kept only on your device and are removed when you uninstall the app.
Playing with a friend or online
To connect two players, the app uses Google Firebase (Firebase Authentication and Cloud Firestore). When you open the app with an internet connection it receives:
- An anonymous ID, a random identifier created for your copy of the app. It is not linked to your name, email address, phone number or Google account.
- Game data: the cards, moves, game code and times of each online game you play.
- Chat messages you send in an online game.
- Reports: if you report another player, their last chat messages in that game (up to 10), the game code and both players’ anonymous IDs are sent to us so we can review them. Blocking a player is only stored on your own device.
The game data and chat messages are visible to the other player in that game. They are stored by Google on our behalf in Firebase, in London (United Kingdom).
What we do not collect
The app does not ask for your name or email address and does not access your contacts, location, photos or microphone. The game itself contains no analytics. We do not sell your information. The app has no ads and no purchases.
Older versions
Android versions before 0.6.0 showed ads from Google AdMob between games. If you still use one of them, Google receives information from your device to deliver and measure ads and prevent fraud, such as its advertising ID, IP address (used for an approximate location), device type and how you interact with the ad. How Google uses this information: policies.google.com/technologies/partner-sites. Updating the app stops this. You can also reset or delete your advertising ID in your phone's settings.
How long data is kept
Online game data and chat messages are only needed while a game is played. Finished and abandoned games may be deleted at any time, and we aim to delete them within 12 months. Reports are deleted once they have been reviewed, and within 12 months at the latest.
Your rights and deleting your data
You can ask us to see or delete the data connected to a game you played. Email hjonakapall@gmail.com with the game code and roughly when you played. You can also complain to the Icelandic Data Protection Authority, Persónuvernd.
Children
The app is not aimed at children under 13. Online chat is with other players, so younger children should play against the phone.
Changes
If this policy changes, the new version will be published on this page with a new date.
