Card Adventurers Privacy Policy
PLAYSEED ("we") processes the personal information of players of the mobile game Card Adventurers ("the game") in accordance with the Personal Information Protection Act of Korea and other applicable laws, and discloses this policy to protect your rights.
Effective date: October 29, 2026
1. What we process and why
The game has no sign-up. On first launch an anonymous account is created, and we process only what is needed to provide the game. This information is processed to perform our agreement with you, so it is explained here rather than asked for as separate consent.
| Data | Purpose | Kept until |
|---|---|---|
| Account identifier (anonymous account ID issued by Firebase) | Telling players apart, cloud save, rankings | Account deletion |
| Guest identifier (device identifier, or a random value made by the app) | Telling guest players apart | Account deletion. A guest account that is not linked to Google or Apple is deleted, with its save, 90 days after its last sign-in |
| Game progress (save: progress, deck, records, settings) | Saving and restoring progress, continuing on a new device, statistics for balancing and improving the game | Account deletion |
| Nickname | Shown in the game and on the rankings | Account deletion |
| Ranking records (score, turns, hero used, time, the deck and relics of that run, chosen title) | Rankings, daily challenge prizes, statistics for balancing and improving the game | Account deletion |
| Reports (the reporting player's account ID, the reported player's account ID and nickname, the reason, the ranking board, the time, the app version, the outcome) | Reviewing and acting on objectionable nicknames and records, handling objections | One year after handling (to see repeat offences). The reporter's account ID is removed if they delete their account |
| Hidden players list (account IDs of players you hid) | Keeping those players' records out of your rankings | Until you unhide them or delete your account |
| With Sign in with Apple: the user identifier Apple provides | Linking and signing in | Account deletion or unlinking |
| With Google sign-in (Android): Google Play Games user identifier and display name | Linking and signing in | Account deletion or unlinking |
- We do not collect your name, email address, phone number, location, contacts or photos. Sign in with Apple does not ask for your name or email.
- Your nickname, account tag, title and ranking records (including that run's deck and relics) are visible to other players on the ranking screen. Please do not use your real name or other identifying information as a nickname.
- Statistics for improving the game are only totals across many players (win rate per hero, how often cards and relics are used, and so on). They are not used to identify anyone and are not given to third parties.
- Access records (time of access, app version) may be created automatically while you use the service.
2. Advertising
The game shows rewarded ads (ads that give an in-game reward when watched to the end), provided by Google LLC's AdMob.
- Data processed: device identifiers such as the advertising identifier (IDFA on iOS, advertising ID on Android), approximate location estimated from the IP address, ad views and clicks, app crash and performance data
- Purpose: showing ads, measuring ad performance, preventing invalid clicks
- On iOS the game first asks whether you allow tracking. If you do not, ads are shown without the advertising identifier. On Android you can reset or delete the advertising ID in the device's ad settings.
- Ads are optional; you can play the whole game without watching any.
- How Google uses this data: https://policies.google.com/technologies/partner-sites
3. Sharing with third parties
We do not provide your personal information to third parties. The advertising data in section 2 is sent through the ad SDK to Google LLC (United States and elsewhere) when ads are shown and is processed under Google's policies; a public authority may also request data through lawful procedures.
4. Service providers and transfers abroad
We do not run our own servers; accounts, cloud saves and rankings use Google's Firebase. Your information is therefore transferred abroad and processed as follows.
| Item | Details |
|---|---|
| Recipient | Google LLC (Firebase) / privacy contact: https://support.google.com/policies |
| Countries | The United States and other countries where Google runs data centers |
| When and how | Sent over encrypted network connections when the game runs and saves |
| Data | The account identifier, guest identifier, game progress, nickname, ranking records and linked sign-in information in section 1 |
| Purpose | Account authentication, cloud save, rankings |
| Kept until | Account deletion |
- If you do not want your information transferred abroad, you can delete your account. Online features such as cloud save and rankings will then be unavailable.
- Sign in with Apple is handled by Apple Inc. and Google sign-in by Google LLC, under their own privacy policies.
5. Deletion
- When you use Settings > Delete Account in the game, your cloud save, ranking records and account are deleted without delay, together with the data on your device.
- Uninstalling the app removes the data on your device but not your account on the server. To remove server data, delete your account in the game or contact us below.
- A guest account that is not linked to a Google or Apple account is deleted automatically, together with its cloud save and ranking records, 90 days after its last sign-in. Sign in once within 90 days, or link an account, to keep it.
- Electronic files are deleted so that they cannot be recovered. We currently keep no data under any legal retention obligation.
6. Your rights
You may at any time ask to access, correct or delete your personal information, or to stop its processing.
- Account and data deletion: Settings > Delete Account in the game, or email us (please include your nickname and in-game player ID).
- Other requests: email us and we will reply within 10 days.
- You may also exercise these rights through a legal representative or an authorized person.
7. Children
We do not knowingly collect personal information from children under 14 (under 13 in the United States). If we learn that a child is using the game, or a parent or guardian asks, we delete that information without delay.
8. Security
- All communication is encrypted (HTTPS/TLS).
- Server security rules let each player access only their own saved data.
- We process only the minimum information needed and keep access to it to a minimum.
9. Cookies
The game does not use cookies. It stores only a value on your device to tell guest players apart.
