Abyss Survivor: Cyber Rogue Privacy Policy
Effective: September 23, 2026 · last updated: September 25, 2026
1. Scope
This policy applies to GYUFORGE's Android app Abyss Survivor: Cyber Rogue (심연의 생존자: 사이버 로그), package com.abyss.survivor. It is separate from GYUFORGE's general website privacy policy.
2. Information processed
- Account: When you connect Google, we process its unique account identifier, a credential used for verification, the provided email address, display name and profile photo, an internal user ID, and session information. We do not receive your Google password.
- Game progress: The device or signed-in account's server profile may store credits, ships and parts owned/upgraded/equipped, stage, achievement and story progress, attendance and rewards, gacha pity state, language and audio settings, and purchase-related state. Attendance records are also stored on the server.
- Guest play: Progress without sign-in is stored in the app's local device storage. Android automatic backup is currently disabled, so guest progress may not be recoverable after uninstalling the app or clearing its data.
- Payments: Google Play processes in-app purchases and subscriptions. When a signed-in account makes a purchase, GYUFORGE's server receives product IDs, purchase status and identifiers, and grant, spending, subscription and refund records to verify purchases, deliver rewards, prevent duplicate grants and process refunds. GYUFORGE does not directly receive or store card numbers or other payment-method details.
- Ads: Google Mobile Ads (AdMob) and UMP SDKs are included, but ad requests are disabled in the current release build. Internal testing uses sample ads and UMP consent/privacy choices. If ad requests are enabled, Google may process IP addresses, device/account identifiers such as advertising ID, app interactions, and diagnostics for ads, analytics, and fraud prevention.
- Technical data: The account API temporarily uses request IP addresses for rate limiting. Technical information needed to handle errors, security incidents and support requests may be processed. This does not claim use of a separate analytics SDK.
3. Purposes
We use data as needed to provide the game, authenticate Google accounts, save and restore progress, grant attendance rewards without duplicates, verify purchases and subscriptions, manage entitlements and refunds, manage ad testing and privacy choices, prevent abuse, provide support, and meet applicable legal obligations.
4. Third-party services
Google Sign-In/Identity and Google Play Services support sign-in; Google Play Billing supports purchases and subscriptions; Google Mobile Ads and User Messaging Platform support internal-test ads and consent choices. Each service may process data under its own policy.
5. Retention
- Guest game data is stored on the device and may be erased by clearing app data or uninstalling the app.
- Account identifiers, profile and attendance data are retained while the account is needed. The scope and duration of any retention after deletion are listed below.
The following describes what GYUFORGE may retain after account deletion and for how long. If a record does not exist, there is nothing to retain.
- Game account identifiers, server profile, progress and settings, attendance and rewards, sessions, and internal-test purchase records not subject to a legal retention duty: deleted upon a verified full-account deletion request, with no additional retention period.
- If a paid transaction actually occurs and Korean e-commerce record-retention law applies, contract, withdrawal, payment and delivery records: 5 years from creation of the record. Only the minimum legally required transaction record is kept separately, not the entire game account or progress.
- Consumer complaint and dispute records subject to Korean e-commerce record-retention law: 3 years from creation of the record. Deletion-request emails and ownership-check materials outside that category are deleted after processing and reply, with no additional retention period.
Legally retained records are kept separately from other account data, used only for that purpose, and erased when the retention period ends. Google Play may separately retain its own purchase history, which GYUFORGE cannot delete.
6. Account and data deletion
You may request deletion of your app account and server-stored game data by email. The app does not currently have a direct deletion function. The steps, ownership check and possible retained records are explained here:
7. Children and age
Please check the app's Google Play listing for its applicable audience and age information. For questions about a child's data or a parent/guardian request, contact us below.
8. Security
The account API applies authentication and access controls and requires HTTPS for remote account traffic. Session tokens are stored as hashes on the server. We design the service to process necessary information, although no transfer or storage method is perfectly secure.
9. International processing
Google services and account-server infrastructure may process information outside your country. This policy does not name an unverified storage region.
10. Changes
If the game's data practices change, we will update this page and its last-updated date. We will also review it before enabling ads in a general release build.
