What data we collect

When you sign in and play online matches, we process the following data:

— Sign-in data: the identity token (ID token) of your Google or Apple account, the email address your sign-in provider passes along, and a Firebase user ID (UID) that identifies your game account.

— Profile data: the player name, team name and motto you enter yourself, plus game preferences synced to your profile (for example settings, calibration and unlocked boules).

— Game data: wins, losses, ELO rating, throw statistics (for example best and average throw and hit accuracy) and online match turn data (for example throw results).

We do not collect location data, contacts, photos or other data from your device. The game contains no analytics, no ads, no tracking and no purchases.

Why we process data

The data is used only to run the game: finding opponents in online play (matchmaking), showing leaderboards, and storing your profile and progression. The legal basis for processing is providing the game service to you (contract, Article 6(1)(b) of the EU General Data Protection Regulation).

Where data is processed

Online play data is stored in Google's Firebase service (project kokuky-alpha-staging) on servers located in the EU (Google Cloud, europe-west1, Belgium). Google acts as a data processor on behalf of the controller.

Public data

Please note that your player name, team name and statistics (wins, losses, rating and throw statistics such as best and average throw and hit accuracy) are visible to other players on the leaderboard and in matches. Do not use a player or team name containing information you do not want to show to others.

Data stored only on your device

Practice progression and the local save file stay on your own device and are removed when you delete the game. If you are signed in, the profile and game data described above are additionally synced to the Firebase service.

Retention

We keep your data for as long as your game account exists. When your account is deleted, your profile, leaderboard row and matchmaking data are deleted from the Firebase service without undue delay. Completed matches remain in your opponents' match history as match records showing your player name at the time of play and the course of the match; you can request anonymization of these records by contacting the address above.

Your rights

Under the EU General Data Protection Regulation (GDPR) you have the right to access your data, the right to have inaccurate data rectified, and the right to request erasure of your data.

You can delete your game account and its online data directly in the game settings via POISTA TILI (Delete account). You can also send any data requests to antikainen.m@gmail.com.

You also have the right to lodge a complaint with a supervisory authority. In Finland the supervisory authority is the Office of the Data Protection Ombudsman (tietosuoja.fi).

No tracking, no ads, no sale of data

We do not use analytics or tracking tools, we do not show ads, and we do not sell or share your data with third parties for marketing.

Changes to this policy

If this policy changes, the updated version is shown in the game. Material changes will be announced separately.
