This privacy policy applies to the Planets vs Black Holes: Duel app for Android and iOS, together with its online game server and any related services operated by Hlib Chornenkyi (collectively, the "Application"). Hlib Chornenkyi is the developer of the Application and the controller of your personal data, and is hereby referred to as the "Service Provider". Contact: 4037637@gmail.com.

Single-player games against the computer work without an account and without sending any personal information. No registration is required to play. Your settings (sound, vibration, language and similar) are saved only on your device.

When you open the online part of the Application (online duels, slots, profile), the Application connects to the Service Provider's game server and creates a game account. The following information is processed:

• Game account identifiers. A random identifier generated on your device and the account identifier on the game server. Used to keep your game profile between sessions.
• Nickname. A randomly generated nickname, or, if you sign in with Google or Apple, your first name. Shown to other players.
• Google or Apple sign-in (optional). If you choose to link your Google or Apple account, the server stores the account identifier, your first name and (for Google) your profile photo. Your last name and e-mail address are not stored: the server deletes them immediately after sign-in. Your first name and photo are shown to other players.
• Profile photo (optional). If you choose your own photo from the camera or gallery, only that photo is uploaded to the game server and shown to other players; the Application does not read your other photos. Before it is accepted, the photo is checked for nudity by an automated model running on the Service Provider's own server; the photo is not sent to any third party for this check. Other players can report a photo; a photo reported several times is hidden until it is reviewed by the Service Provider.
• Game activity. Online duels you play (moves, scores and results), rating and rank, experience, statistics, friends and blocked players. Your rating, rank and statistics are shown to other players.
• Fair-play and moderation records. Cancelled matches, wrong room codes and refused or reported photos. Used to apply temporary restrictions against abuse.
• Diagnostic logs (optional). Only when you press the button to send a log, a technical log of the game session is sent to the server to investigate a problem. It contains the app version, device model and operating system version (as reported by the device's web view), screen size, performance figures and, if you played online recently, that duel's technical data. It does not contain your name or photo.
• Country. Once a day, when you go online, the server looks up the country of your IP address in a local database (IP Geolocation by DB-IP) on the Service Provider's own server; the IP address itself is not stored. The server keeps one country per day for the last 90 days, and the most frequent one is shown as a flag next to your name. You can hide it from other players in the profile (SHOW COUNTRY).
• Technical data. Your IP address is used to deliver network traffic, to determine your country (see above) and to protect the server. It is not used to identify or track you. It may appear in the server's technical logs, which are kept for a limited time for security and troubleshooting and then deleted. When the game cannot reach our server, it checks whether the device itself is online by requesting the standard connectivity-check pages of Google and Apple (the same ones Android and iOS use); nothing is sent with that request beyond what any web request carries.

This information is used only to provide the online game: matchmaking, duels, profiles, rating, friends, moderation of profile photos, protection against abuse and fixing problems. The Application contains no advertising and no third-party analytics or tracking tools, does not use the advertising ID, and does not sell your information or use it for profiling.

The Application uses the Internet connection (online play) and vibration (game effects; can be turned off in the settings). The camera and photo gallery are opened through the system picker only when you choose to set a profile photo. The Application does not access your contacts, location, microphone or files.

Game account, game activity and diagnostic logs you send are processed to provide the online game you requested (performance of a contract). Google or Apple sign-in and a profile photo are processed on the basis of your consent, which you can withdraw at any time by removing them in the Application. Fair-play records and technical logs are processed on the basis of the Service Provider's legitimate interest in keeping the game fair and the server secure.

The game server is hosted in the European Union (Germany) by the hosting provider Hetzner Online GmbH, which stores the data on behalf of the Service Provider and does not use it for its own purposes. Data is encrypted in transit (TLS). Access to the server is limited to the Service Provider.

Your game account and its data are kept until you delete the account. Records of played duels are kept to ensure fair play; after your account is deleted they no longer contain anything that links them to you. Diagnostic logs are kept only as long as needed to investigate the problem. Technical server logs are kept for a limited time and then deleted.

You can delete your account at any time in the Application: PROFILE → DELETE ACCOUNT. This deletes your game account, nickname, linked Google or Apple account, profile photo, rating, statistics, friends and all other data tied to the account. You can also request deletion without the Application: see how to delete your account.

No. The Application does not collect precise or approximate location of your device.

No information is shared with or sold to third parties. Other players see your nickname or first name, profile photo, country (unless you hide it), rating, rank and statistics. The hosting provider stores data only on behalf of the Service Provider. If you use Google or Apple sign-in, Google or Apple processes that sign-in under their own privacy policies. Information may be disclosed if required by law.

The Application is not intended for children under 13 years of age, or such higher age as required by applicable law. The Service Provider does not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information, contact the Service Provider and it will be deleted.

No security system is completely secure. If a breach occurs involving your personal data, the Service Provider will notify you and the authorities as required by applicable law.

You can access, correct, export or delete your data, object to its processing, and withdraw consent for optional features (Google or Apple sign-in, profile photo) at any time by removing them in the Application or by contacting the Service Provider at 4037637@gmail.com. The Service Provider replies within 30 days. If you are in the EEA or the UK, you also have the right to lodge a complaint with your data protection authority.

The Service Provider may update this Privacy Policy from time to time. The Service Provider will notify you of material changes by posting the updated Privacy Policy with an effective date. Where required by law, the Service Provider will seek your consent to material changes before they take effect.

Previous versions of this Privacy Policy will be maintained and made available upon request by contacting the Service Provider at 4037637@gmail.com.

This privacy policy is effective as of 2026-10-04

If you have any questions regarding privacy while using the Application, or have questions about the practices, please contact the Service Provider via email at 4037637@gmail.com.
