Privacy Policy

The short version

• You never give us an email, password, phone number, or real name.
• No ads, no tracking, no third-party analytics, and we never sell your data.
• Your display name, avatar, country, and game results are shown to other players on leaderboards and player cards.
• You can permanently delete your online account at any time in Settings.

Your account

Online features (ranked games, the Daily puzzle leaderboard, and player profiles) run on Supabase, a hosted Postgres database service. When you use the app, you are given an anonymous account automatically. We never ask for an email address, password, phone number, or real name.

A random account ID and a session token are stored on your device so the app can keep you signed in to that anonymous account.

Information stored on our server

• Display name. Chosen by you and unique across all players. Names are filtered for offensive words. A starter name (for example, "Sergeant48213") is assigned by default.
• Avatar. The avatar style and color you pick.
• Country (optional). Only if you choose one. If you don't, your profile shows Earth.
• Ranked games. Mode, track, win or loss, time, ELO change, and ELO.
• Daily puzzle results. Date, whether you won, and your time.
• Infinite mode total. The total number of mines you have swept.
• Medals and badges. Medals you have unlocked, up to 3 pinned medals, and daily leaderboard badges.
• Name reports. If you report a name, or someone reports yours, we store which account made the report, which name was reported, and when.

What other players can see

Your display name, avatar, country, ELO and division, ranks, stats, medals, and the month you joined appear on global leaderboards and on your player card, which other players can open.

Information stored only on your device

Your gameplay settings, board themes, local stats and history, and your Infinite world are kept on your phone and are not sent to our server.

What we don't do

• No ads and no advertising identifiers.
• No tracking and no third-party analytics.
• We do not sell your data or share it for marketing.
• The app does not access your location, contacts, photos, microphone, or camera.

Name moderation

Any player can report a display name from a player card. The developer may reset a reported name, and a name that receives 3 reports is reset automatically.

Deleting your data

In the app, go to Settings > Delete my online account. This permanently deletes your online account and everything linked to it on our server: your profile, results, badges, medals, and reports.

Data stored on your phone stays there until you delete the app. You can also email us at minesweeperchallenge0@gmail.com to ask us to delete your account.

Children

Minesweeper Challenge is not directed at children under 13.
