Dragoncoil: Snake Dungeon works offline. Progress and audio preferences stay on this device; platform services handle ads and purchases, and the game does not profile players.
Data stored on your device
The game writes local JSON files inside the device sandbox. user://ouroboros_save.json stores highest floor, best records by difficulty, expedition/floor/boss totals, tutorial state, Dragon Crystals, unlocks, and upgrade state; user://ouroboros_save.bak.json keeps the previous progress save so a damaged file can be recovered. The Crystal product is consumable: purchased Crystals and progress are stored only on this device and cannot be restored as a purchase. After deleting the app, clearing app data, or changing devices, unused Crystals may not be recoverable. user://audio_settings.json stores mute state plus volume values for Master, Music, SFX, and UI. These files do not contain a name, email address, account, contacts, precise location, advertising identifier, or payment information.
Developer backend and network requests
This version has no developer backend, account system, or game-data sync. Its code does not use HTTP, WebSockets, cloud databases, or remote telemetry services; if the native platform bridge is enabled, only platform ad and store services connect under their own rules. Gameplay, saved progress, and audio settings are handled on the device.
Cloud sync, backups, account links, and Google Drive
The game does not implement its own cloud sync, developer-managed backup, or account-linking feature. There is no Google Drive integration, OAuth sign-in, or OAuth scope. It therefore cannot access an app data folder and cannot read, list, create, or modify any other Google Drive files. Because there is no account link, there is no linked cloud data to retain after unlinking. The device operating system may back up the app sandbox under the user's Apple or Google backup settings; that is not cloud sync managed by this game, and the developer cannot read that backup.
Third-party services and data they receive
The developer does not receive gameplay progress, unlocks or statistics. Mobile builds use Google Mobile Ads (AdMob) for banner and rewarded ads. The SDK may process IP-derived approximate location, device or app identifiers, ad/product interactions, crash, performance and other diagnostic data for ad delivery, frequency capping, aggregate reporting, SDK analytics and fraud prevention. Some SDK data may be linked to a device or identifier; it is not an upload of game saves to the developer. Apple StoreKit and Google Play Billing process purchase transactions under their own terms; the game receives display or verified transaction results. Public pages use Firebase Hosting, which processes IP, browser/device and request-time data. The app has no Firebase SDK. Gmail processes support senders, messages, attachments and headers only for support.
Advertising, analytics, and tracking
The iOS build requests non-personalized ads only: all banner (including resumed/reloaded) and rewarded requests send npa=1, publisher first-party ID is disabled, and the app does not request ATT authorization or use IDFA for cross-app/site advertising tracking. Non-personalized does not mean no data processing: AdMob may still use approximate location, identifiers, interactions and diagnostics for ad delivery, frequency capping and aggregate reporting as described above. UMP consent and privacy options remain required; ads stay blocked until necessary consent is resolved. Existing Android releases still follow UMP choices and Google's policies; the iOS setting does not silently change published Android builds. The developer operates no gameplay analytics or crash-reporting backend. Public pages have no analytics pixels or remarketing tags.
Retention and deletion
Local progress, Crystals and audio settings remain until the user chooses Delete local game data on this page, removes the app, or clears app data. The deletion control removes the two files above and resets the current in-memory settings; it cannot be undone. Consumable Crystal purchases cannot be restored; after deleting the app, clearing app data, or changing devices, unused Crystals may not be recoverable. Removing the app normally removes the active device sandbox, but device backups may retain a copy under Apple/Google settings and must be managed there by the user. The developer has no copy of game data. Support emails remain in the support mailbox until they are no longer needed to handle the request or the user asks for deletion; there is currently no fixed automatic deletion period. A user may email us to request deletion of support correspondence, subject to legal duties or backup limits.
Children's privacy
The game does not require an account or personal information and contains no child behavioural analytics or social features. The game does not build its own advertising profile; whether platform ads are personalised is controlled by the user's UMP privacy choice and Google's policies. If a child voluntarily contacts us by email, a parent or guardian may use the email below to ask about or request deletion of that support correspondence.
