Abyssborn Privacy Policy

Abyssborn ("the Game" or "the Service") values your privacy and complies with applicable laws. This policy explains what information the Game (iOS & Android apps and the web version) collects, and how it is used, stored, and deleted.

1. Information We Collect and Why

• Auto-generated identifier and nickname: A random unique identifier (UUID) created on first launch, and the nickname you enter (default e.g. Guest1234). Used to display leaderboard rankings, process feedback, and prevent duplicates. Stored on your device and sent to the server when submitting scores or feedback.
• Game records: Your play results — survival time, level reached, kills, and the phase reached. Stored on the server at the end of a run to provide the online leaderboard.
• Feedback data: When you send feedback in-game, the message, category (bug · improvement · other), nickname, identifier (UUID), originating screen, game version, screen resolution, browser information (User-Agent), and the connecting IP address are stored on the server. This is used to reproduce bugs and classify suggestions. Please avoid including personally identifiable information in your message.
• On-device settings (local storage): Language, audio (music/effects) volume, restart count, and the timestamps of your last feedback/ad. Stored only on your device (localStorage) and never transmitted externally.
• Advertising identifier: An advertising identifier — the IDFA on iOS and the Android Advertising ID (AAID) on Android — may be used for personalized ads (see Section 6).

2. Data Retention and Disposal

Category	Retention period
On-device data (settings, identifier, etc.)	Until you delete the app or clear the data
Server-stored game records (ranking)	Kept as needed for operation; deleted upon request
Server-stored feedback	Discarded after the issue/improvement is addressed; deleted upon request

Once the retention period expires or the purpose is fulfilled, the data is disposed of without delay. Electronic files are deleted using methods that make recovery impossible.

3. Provision to Third Parties

As a rule, we do not provide your personal information to third parties, except in the following cases:

• When you have given prior consent
• When required by law or a lawful request from an investigative authority

4. Processing Entrustment

We entrust processing for advertising as follows. Game records and feedback are stored on a server operated directly by the operator.

Processor	Entrusted task
Google LLC (Google AdMob)	In-app ad delivery and ad performance measurement

5. Your Rights and Data Deletion Requests

You may at any time request access to, correction, deletion, or suspension of processing of your personal information. The Game has no login accounts and uses only a random identifier (UUID) and a nickname.

• On-device data: Removed immediately when you delete the app.
• Server data (ranking · feedback): To request deletion, email us the nickname or identifier (UUID) shown in the app at the contact address below.

6. Advertising and Tracking

• The mobile app displays Google AdMob interstitial ads.
• App Tracking Transparency (ATT): On iOS 14.5+, the app requests tracking permission. You can decline and still use all features of the app; in that case non-personalized ads are shown.
• In some regions (e.g. the EU), an ad personalization consent (UMP) screen may be shown.
• You can limit ad tracking in your device settings (iOS: Settings > Privacy & Security > Tracking, Android: Settings > Google > Ads).
• Data processing through AdMob is governed by Google's advertising policies. You can review how Google uses data from sites and apps that use its services at Google's partner policy.

7. Children's Privacy

The Game does not collect login accounts, real names, contact details, or other sensitive or personally identifying information, and uses only a randomly generated identifier.

8. Security

We apply reasonable technical and administrative safeguards to protect personal information, including transport encryption (HTTPS) and restricted server access.

9. Changes to This Policy

This policy may be revised in response to changes in law or the service. Significant changes will be announced on this page.
