Privacy Policy

BrainArena is a free puzzle and word-game site. We try to collect as little personal data as possible. Your game progress and streaks live on your own device. The only data that leaves your browser is the score you submit to the global leaderboard, plus standard server logs and advertising cookies.

The following lives in your browser's localStorage and is never sent to us:

• Your selected language and preferred name.
• Daily streak, total games played, time played, and play history (used by /achievements).
• Per-game records (best Wordle guesses, top TileDrop score, etc.).
• A daily player-count seed (cosmetic).

You can clear it any time from your browser's site-data settings.

When you finish a game and tap Submit, the following is sent to our server and saved alongside other players' entries:

• The display name you typed (24-character limit, anything goes — use a nickname).
• Your score, time, and game-specific metadata (e.g. difficulty, accuracy).
• The selected language and, if your browser provides it, a 2-letter country code.
• The submission timestamp.

We never collect your email, phone, address or any government identifier with these submissions. To request removal of an entry, see Contact.

Our hosting provider records standard request logs (IP address, user agent, requested path, timestamp) for security and abuse-prevention. These are retained for a short period and not combined with any personal profile.

BrainArena displays ads through Google AdSense. AdSense and its partners may set cookies and use device identifiers to personalise ads, measure performance, and prevent fraud. You can manage these via your browser settings or Google's ad settings.

We use a single first-party storage area (browser localStorage), not cookies, for game state. Third-party cookies are limited to the AdSense script described above.

BrainArena is suitable for all ages, but we don't knowingly collect personal data from children under 13. If you believe a child has submitted personal information, contact us and we'll delete it.

You can erase all on-device data by clearing site data in your browser. For leaderboard removal or any data-protection question (access, deletion, correction), email us at the address below.
