KING — PRIVACY POLICY

• Account data: e-mail address, your password (stored only in encrypted/hashed form by our identity provider Supabase), your chosen username and avatar.
• Game data: rating (MMR), match results and rankings, achievements, in-game diamond/ruby balance, cosmetics you own, game statistics.
• Match records: cards played, contracts, round scores and decision times; recorded together with the identities of the players in the match. Used solely for cheat/error detection and to improve game balance and bot artificial intelligence.
• Social data: friend requests and your friend list, party invitations, your online/in-match status.
• Technical data: connection events (disconnection/reconnection, app version, platform, device identifier) and application errors (the error message and the screen where it occurred). This data is kept only to diagnose connection problems and errors.
• Usage data: in-game events such as opening the shop, purchase and ad results, and match start and end. Used to improve the game; this data is kept on our own infrastructure and is not sent to any third-party analytics service.
• Purchase data: for in-app purchases, payment is processed by Apple; your card and payment details never reach us. We record only the transaction identifier, the product purchased and the date.
• Advertising data: ads are shown only when you choose to watch one (to earn diamonds). When you watch an ad, our advertising provider Google AdMob processes data such as device information, IP address and ad interaction under its own privacy policy. The App does not ask for tracking permission and does not use your advertising identifier (IDFA). Only your random account identifier is passed to the advertising provider so that the reward can be credited to your account.
• If you play as a guest, no account data is collected; your progress is stored only on your device.

• To create your account and identify you.
• To match you in online games and calculate rankings.
• To preserve your progress across devices.
• To provide friend features.
• To find and fix connection errors and application errors.
• To verify your purchases, credit diamonds to your account and handle refunds.
• To serve the rewarded ads you choose to watch and credit the reward to your account.

Your data is not sold. Data is shared only with the following providers, and only so that the service can be delivered:

• Supabase: authentication, database, real-time connection.
• Apple: in-app purchases and Sign in with Apple.
• Google: Sign in with Google and — only when you choose to watch an ad — AdMob rewarded ads.

The App contains no other third-party analytics or tracking SDKs. Other players see only your username, avatar, rating and game statistics.

Your account and progress data is kept as long as your account exists; match records for at most 24 months; connection, error and usage records for at most 12 months. Purchase records are kept for as long as required by legal obligations and refund handling. When you delete your account, your account, profile, friendship, invitation and queue data are permanently deleted; the personal link in match records and connection records is severed (anonymised). Result records in other players' match history remain in a form that cannot be associated with your identity (only with a random identifier).

You have the right to access, correct and delete your data. You can permanently delete your account at any time via Settings → Delete account. For other requests you can reach us at the address below.

The App is not directed at users under the age of 13 and does not knowingly collect data from them.

Data is transmitted over an encrypted connection (TLS). Passwords are not stored in plain text. Row-level access rules ensure that each user can access only their own data.

When this policy is updated the date is changed and significant changes are announced within the App.
