Concern — Privacy Policy

Version 2026-10-17

Concern is a board game played on a physical board; the Concern app is its controller. This policy covers the app and the concerngame.com website. The developer is the one named on the app's Google Play or TestFlight page. Questions and requests: hello@concerngame.com.

What the app handles

• Your nickname, and the names you give towers and consortia. The app sends them, with your moves, to the game board you join on your local Wi-Fi; everyone in the game sees them.
• Your moves in the game, sent to the same board.
• On your phone the app keeps its settings, the board you last played on, and your nickname and seat so you can rejoin that game. NEW GAME forgets the nickname and seat; uninstalling deletes everything.

The app has no accounts, analytics, advertising, tracking or crash reporting of its own, and it does not connect to us over the internet: it talks only to the board on your local network. That is what its network permission is for.

What the board keeps

The board holds the nicknames and moves of the game being played until it is reset for a new game.

What we keep

We keep records of games, nicknames included, to analyse and improve the game.

Through Google Play and TestFlight

• If you join the test through a Google Group or an email invitation, we see the email address you joined with. Through the TestFlight public link, Apple shows us neither your name nor your email.
• Google and Apple pass us crash reports and usage counts with your device model and system version, and any feedback you choose to send, screenshots included. What they do with your data themselves is covered by their own privacy policies.

If you are invited to download test builds, we keep your email address with when you were invited, when you first visited and what you downloaded. Cloudflare runs the sign-in and holds the invitation list, under its data processing terms, and may process it outside the EU. A download from the home network is logged with the device's local network address only.

Why, and how long

We use this data only to run the game and the test, to fix the app and to analyse games (GDPR Art. 6(1)(b) and (f)). Nothing is sold or shared with anyone else.

• On your phone: until NEW GAME or uninstalling.
• On the board: until it is reset for a new game.
• Game records: as long as they help develop the game.
• Email addresses, invitations and download records: until the test ends, or sooner if you ask.

Security

The app talks to the board over your Wi-Fi without encryption, so someone on the same network could read the game's traffic — don't type anything private into it.

Your rights

You can ask what we hold about you, and have it corrected or deleted, or object to its use: write to hello@concerngame.com. You can also complain to a data protection authority — in Poland, the President of the Personal Data Protection Office (UODO).

Changes

When the app or the test changes, this page changes with it; the version date at the top says which one you are reading.
