Brimfall Privacy Policy
Brimfall ("the game") is a real-time strategy game published by Martin Kral ("I", "me"). This policy explains what data the game handles. The short version: I do not collect, store or sell your personal data, and the game has no accounts, ads, analytics or in-app purchases.
Data stored on your device
The game saves your display name, settings and campaign progress in the app's local storage on your device. This data never leaves your device and is removed when you uninstall the app or clear its data.
Online play
Single-player modes (campaign, daily challenge, games against bots) work without sending anything anywhere. If you use Host online or Join online, the game connects over an encrypted WebSocket (wss) to a free public message relay (currently HiveMQ, with EMQX as a fallback). Through that relay the game sends:
- the display name you typed,
- your in-game commands and the game state, so other players in the same game see the match,
- for hosted games, a four-letter game code and basic game details so the game can appear in the public game list.
Please note:
- These relays are operated by third parties. I do not run them and do not receive or keep this data. They may log connection information (such as IP addresses) under their own privacy policies.
- Online games are not private. Anyone who knows or guesses a game code can join, and the relay operators can technically see the traffic.
- There is no chat. Other players in your game only see your display name and your actions.
- Please do not use your real name or any personal information as your display name.
What the game does not do
- No accounts or sign-in.
- No advertising and no advertising identifiers.
- No analytics, tracking or crash-reporting services.
- No access to your location, contacts, photos, camera or microphone.
- No in-app purchases or payment data.
- No sale or sharing of personal data with anyone for marketing.
Children
The game does not knowingly collect personal information from anyone, including children. Because online play shows a free-text display name to other players, parents may prefer to keep younger children to the offline modes.
Changes
If the game's data handling changes, for example if I move to my own server, I will update this page and the date above.
