Privacy Policy
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. 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 game does not send progress, unlocks, or statistics to the developer. If a native platform bridge is enabled, Apple/Google and the relevant ad service process ad requests, rewarded-ad results, and purchases under their own terms; the game receives only display or transaction results and does not send save data. The public privacy and support site is served by Firebase Hosting. When a user opens that site in a browser, Firebase/Google processes ordinary web-request data, such as IP address, browser/device information, and request time, to serve the page. The app contains no Firebase SDK and does not connect to Firebase. If a user emails support, Gmail processes the sender's email address, message content, attachments, and email headers; we use that correspondence only to handle support.
Advertising, analytics, and tracking
The game can show banner and rewarded ads; when a native platform bridge is enabled, the platform or ad service may process device and request data needed to serve them. The game does not use ad attribution, analytics, crash reporting, behavioural profiling, personalised ads, cross-app or cross-site tracking, or its own tracking domains. The iOS export configuration disables App Tracking Transparency tracking. The public website uses no cookie banner, analytics pixels, advertising tags, or remarketing tags.
Retention and deletion
Local progress 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. 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, personalised advertising, or social features. If platform ads are enabled, they are non-personalised. 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.
