Game Master Privacy Policy

1. About This Policy

Game Master is a tabletop role-playing game app developed and published by Frozen Dungeon Studios ("Frozen Dungeon", "we", "us"). This policy explains what information the Game Master app accesses, stores and sends, and who can see it. It applies to Game Master on Windows (including copies distributed through Steam) and on Android (including copies distributed through Google Play).

This policy covers the app. Stores and platforms you use to get the app, such as Steam and Google Play, have their own privacy policies, described in Third-Party Services.

2. Information Game Master Handles

Game Master works with the following kinds of information. The table shows where each one goes.

Game Master does not access your location, contacts, microphone, calendar, phone or SMS data, advertising ID, or other device identifiers such as IMEI or serial numbers.

Device permissions (Android)

• Internet / network access (INTERNET): required by Android for any network connection, including connections between devices on your local network. Game Master does not connect to internet servers.
• View network and Wi-Fi state (ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE): used to find this device's local address and to help with reconnecting during LAN play.
• Wi-Fi multicast (CHANGE_WIFI_MULTICAST_STATE): lets the app hear session announcements on your local network so hosted sessions appear in the Join list.

Game Master does not request camera or storage permissions. When you import a picture, Android's own photo picker lets you choose a single image. "Take Photo" opens your device's camera app, and only the photo you take and accept is returned to Game Master. Importing a sound uses Android's document picker in the same way.

Windows

On Windows, importing images or sounds uses the standard Windows file dialog. The first time a PC hosts a LAN session, Windows Firewall may ask whether Game Master may accept connections on your network.

3. Information Stored on Your Device

Everything you create in Game Master is saved locally in the app's private storage on your device:

• campaigns, story, locations and maps;
• characters, NPCs, monsters, items and encounters;
• sessions, including positions, HP, turn order, messages and the Session Log;
• imported images (portraits, tiles, backgrounds) and imported sounds (converted to WAV);
• settings such as UI colors, theme, sound preferences, editor preferences and which tips you have seen;
• your LAN player identity: a randomly generated ID, the name you play under, and which character you last used in each session, so you can rejoin as yourself.

On Windows these files are kept in %APPDATA%\com.gamemaster\game_master in your user profile. On Android they are kept in the app's private storage, which other apps cannot read.

While LAN Multiplayer is running, Game Master keeps a short connection log in memory (for example "connected", "reconnecting") to help diagnose network problems. It is also written to the device's standard system log, like most apps. It is not saved to a file by Game Master and is never sent to us.

On Android, if you have turned on device backup in your Android settings, Android may include Game Master's app data in your device backup to your Google account. That backup is handled by Google under your Google account settings and Google's privacy policy; Frozen Dungeon cannot access it.

4. Local Network Multiplayer

LAN Multiplayer lets players join a GM's session from other devices on the same local network (the same Wi-Fi or wired network). It does not use the internet or any Frozen Dungeon server. Data goes directly from one device to another on your network, and Frozen Dungeon never receives it.

What the host announces

When a GM opens a session, the host device announces it on the local network about once a second so players can find it. Any device on the same network can receive this announcement. It contains:

• the session name;
• the host device's network name (for example, the computer name set in Windows);
• the port number, the number of connected players, the app's network version, and whether a password is required.

It contains no campaign content. If you would rather not broadcast your device's name, you can change the device name in your operating system settings.

What is sent when a player joins

• Player to host: the player's name, a random player ID generated by the app, the chosen character, the session password if one is set, and the player's actions (such as moves, attacks and dice roll requests).
• Host to player: the list of characters available to pick and the game state that player is allowed to see: the map, visible creatures, their own character, messages meant for them, dice results and the Session Log. Hidden information (unrevealed creatures, GM notes, other players' private messages) is removed on the host before anything is sent.

The host device is in charge: it checks each action, applies results and saves the session. Players' devices hold the game information they receive in memory while the session is open, so they can catch up after a short disconnection; it is not saved to their storage. The only LAN information a player's device saves is its own player identity (random ID, name and last character).

Encryption

LAN traffic between Game Master devices is not encrypted, and the optional session password is sent as plain text. Other devices on the same network could, with the right tools, observe it. Use LAN Multiplayer on networks you trust, such as your home network, and don't use a password you use anywhere else.

5. Information Frozen Dungeon Collects

Frozen Dungeon does not collect any personal information or game data through the Game Master app. The app has no analytics, no crash reporting, no telemetry and no account system, and it does not connect to any Frozen Dungeon server. We never receive your campaigns, maps, characters, sessions, messages, imported files or LAN traffic.

If you contact us (see Contact), we will receive whatever you choose to send us, such as your forum username and message, and use it only to respond.

Store platforms may give us aggregated reports, as described below.

6. Third-Party Services

Game Master does not include any third-party SDKs for advertising, analytics, crash reporting, social login or cloud storage. It uses the open-source Flutter framework and standard platform features (for example the Android photo picker), which run on your device.

Steam (Windows)

If you get Game Master through Steam, Valve operates the Steam client, your Steam account, purchases, downloads and updates. Steam handles that information under the Valve Privacy Policy. Game Master does not currently use Steamworks features such as Steam Cloud, achievements, Steam networking or Steam friends, and it does not read your Steam account information. Valve may provide us with aggregated sales and usage statistics, which do not identify you.

Google Play (Android)

If you get Game Master through Google Play, Google operates the Play Store, your Google account, purchases, downloads and updates under the Google Privacy Policy. Depending on your device settings, Google may share aggregated statistics and anonymous crash or performance reports with developers through the Google Play Console. Frozen Dungeon does not receive your payment details.

7. Advertising and Tracking

Game Master contains no advertising and no advertising SDKs. It does not use your advertising ID, does not track you across apps or websites, does not build profiles, and does not sell or share personal information.

8. Data Storage and Retention

• Data on your device: kept until you delete it in the app, clear the app's data, or uninstall the app. Game Master does not upload it anywhere.
• Data received over LAN: the host saves the session (what each character did, the messages and the Session Log) until the GM deletes the campaign. Players' names and player IDs are held by the host in memory only and are forgotten when it stops hosting. A player's device discards the game information it received when the player leaves the session or closes the app.
• Data collected by Frozen Dungeon: none through the app. Messages you send us through the forum are kept as long as needed to respond or as the forum keeps posts.
• Third-party platforms: Steam and Google Play keep information under their own retention policies.

9. Data Deletion

• Inside the app: delete characters, monsters, maps, items, encounters and imported images from their screens. Deleting a campaign also deletes its sessions and Session Logs.
• All app data on Android: Settings › Apps › Game Master › Storage › Clear storage, or uninstall the app.
• All app data on Windows: uninstall the app and delete the folder %APPDATA%\com.gamemaster\game_master.
• LAN data on other devices: the host forgets players' names and IDs when it stops hosting. Your character's actions are part of the GM's saved session; ask the GM to delete the campaign on their device if you want them removed. Players' devices don't save game information they receive.
• Data held by Frozen Dungeon: we hold no app data about you, so there is nothing to request. To remove something you posted on our forum, contact us as described below.
• Steam or Google Play data: use the tools Valve and Google provide for your account.

Uninstalling the app removes your campaigns permanently unless you have a backup. Game Master has no cloud saves.

10. Security

Your Game Master data lives in the app's private storage on your device, protected by your operating system. Keep your device secure with a screen lock and up-to-date software. The app does not send your data to us, which limits where it can be exposed.

For LAN Multiplayer, the host removes hidden information before sending game state to each player, and you can require a session password. LAN traffic is not encrypted (see section 4), so play on networks you trust. No method of storing or sending data is completely secure, and we cannot guarantee absolute security.

11. Children's Privacy / Intended Audience

Game Master is a tabletop role-playing game tool intended for the audience and age rating shown on its Steam and Google Play store pages. Frozen Dungeon does not knowingly collect personal information from children, and the app does not collect personal information from any user. If you believe a child has sent us personal information through our forum, contact us and we will delete it.

12. Changes to This Policy

We will update this policy when Game Master's features or data practices change. If we add features that handle data differently, such as cloud saves, internet multiplayer, accounts, analytics or crash reporting, we will update this policy and the store disclosures before those features are released, and describe what is collected, why, who receives it and how to delete it.

The current version is always at this address. The effective date at the top shows when it last changed.
