Privacy Policy

Effective 9 November 2026

This privacy policy applies to the AR-TD app for iPhone and iPad (the “Application”). The Application is made by Daniel Ridzoň, a sole trader in the Czech Republic trading as Ridzon Games (the “Service Provider”), who is the controller of the personal data described here. You can reach the Service Provider at support@ridzongames.com.

In short

• The Application has no accounts and asks for no email, age or gender.
• Your game, your camera image and your recordings stay on your device, except what you share with nearby players in a local multiplayer match.
• The Application sends anonymous usage statistics and crash reports to Google’s Firebase, so the Service Provider can see how the game is played and fix what crashes.

What stays on your device

Camera. The camera is used only to place the battlefield in augmented reality on your table. No image or video is sent anywhere.

Recordings and Photos. If you choose to record a gameplay clip, the Application saves it to your photo library. It only adds to your photo library and never reads it.

Your game. Your progress, high scores, saved matches and player name are stored on your device. The Service Provider never receives them.

Local multiplayer

When you play with friends nearby, the Application connects directly to their devices over Wi-Fi, Bluetooth or your local network, using Apple’s Multipeer Connectivity. Nothing passes through a server. The devices in the match exchange:

• your player name and a short random code that tells players apart. Unless you change it in Settings, the player name is your device’s name, which may contain your real name.
• the game state of the match.
• AR mapping data that lets everyone see the battlefield in the same place. This is a map of the surfaces and visual features around the table, built by the device from the camera. It is not a photo or video.

This data is shared only with the devices taking part in the match, and is not kept after the match ends, except in a saved match on your own device. Other players can see the player name you choose, so do not use one you would not want them to see.

What is sent to third parties

The Application uses two Google services:

• Google Analytics for Firebase collects anonymous usage information: a random identifier for this installation of the Application, when it is opened, which screens are used, game events (for example, a match starting or ending, its mode, score and duration, and how smoothly the game ran), the device model, operating system and app version, your language, and the country and region derived from your IP address. Google does not store your IP address.
• Firebase Crashlytics collects crash reports: what the Application was doing when it crashed, the device model, operating system and app version, and a random identifier for this installation.

Neither service receives your name, player name, contact details, location, camera image or recordings. Both are operated by Google, which processes this data on the Service Provider’s behalf, and may process it outside the European Economic Area under Standard Contractual Clauses. Their privacy terms:

• Firebase privacy and security
• Google Privacy Policy

The legal basis for this processing is the Service Provider’s legitimate interest in keeping the Application working and learning how it is used (Article 6(1)(f) GDPR). Where the law requires your consent for analytics, the Application will ask for it before collecting.

The Application shows no ads and does not track you across other apps or websites.

Information you choose to send

If you email the Service Provider, for example with a question, feedback or a bug report, the Service Provider receives what you send, including your email address. This information is used only to answer you and to improve the Application, and is deleted when it is no longer needed for that.

How long data is kept

• Analytics data tied to an installation identifier is kept for 2 months, the retention period set in Google Analytics. Aggregated statistics, which do not identify you, may be kept longer.
• Crash reports are kept by Crashlytics for 90 days.
• Emails you send are kept only as long as needed to deal with them, and at most 12 months after the last message.
• Your game data stays on your device until you delete the Application. Clips you saved to Photos stay there until you delete them.

Your rights

Under the GDPR you have the right to access, correct and delete your personal data, to restrict or object to its processing, and to data portability. To exercise any of these rights, email support@ridzongames.com. You also have the right to complain to a data protection authority; in the Czech Republic this is the Office for Personal Data Protection (Úřad pro ochranu osobních údajů, uoou.gov.cz).

If you are a California resident, you have the right to know what personal information is collected, to have it deleted, and not to be discriminated against for exercising these rights. The Service Provider does not sell or share personal information.

Deleting your data

• Game data: delete the Application. Everything it stored on your device is deleted with it.
• Analytics and crash data: email support@ridzongames.com. Because this data is tied to a random identifier rather than to you, the Service Provider may need your help to find it; if it cannot be found, you will be told. It is also deleted automatically after the retention periods above.

Uninstalling the Application stops all further collection.

Children

The Application is a strategy game suitable for children and adults. It does not ask anyone for personal information, and collects only the anonymous usage and crash data described above. In local multiplayer, a child’s player name is visible to the other players nearby. If you are a parent or guardian and want data about your child’s device deleted, email support@ridzongames.com.

Security

Data sent to Firebase is encrypted in transit, and so is data exchanged between devices in a local multiplayer match. The Service Provider has no servers of its own and keeps no copy of your game.

Changes to this policy

The Service Provider may update this policy, for example when the Application gains new features. The updated policy will be posted on this page with a new effective date. Material changes will be announced in the Application where the law requires it. Previous versions are available on request.
