Privacy Policy

Last updated: August 9, 2026

This policy explains what ClassicWorks stores in your browser for Minesweeper, 2048, and Four in a Row, what is sent to the shared numbered-game record service, and how Cloudflare helps deliver and measure the site.

No account required

ClassicWorks does not require registration, a player name, or a login. You can play Minesweeper, 2048, and Four in a Row without creating a profile.

Data stored in your browser

The site uses browser local storage for your selected difficulty, custom board dimensions and mine count, reveal or flag input mode, random or numbered game mode, most recently selected game number, and aggregate Minesweeper statistics. Statistics include games started, wins, losses, best local completion time, and win streaks for each standard difficulty. Custom games are not added to these statistics because different board configurations are not directly comparable.

For 2048, local storage contains the current board, score, move count, whether 2048 has been reached and play continued, and undo history so the session can resume after a reload. It also contains the local best score and aggregate statistics: games started, games over, times 2048 was reached, highest tile, and total moves. ClassicWorks does not upload this 2048 data or use it for a public leaderboard.

For Four in a Row, local storage contains the current board, player turn, move count, completed-result state, and undo history so the local two-player round can resume after a reload. Aggregate results count rounds started and completed, Player 1 and Player 2 wins, draws, and total moves. ClassicWorks does not upload this data or use it for matchmaking or a public leaderboard.

This information remains on your device. Minesweeper preferences and statistics persist, but an unfinished Minesweeper board is not restored; valid 2048 and Four in a Row sessions are restored locally. You can remove local data by clearing site data for ClassicWorks in your browser. Doing so resets the affected preferences, sessions, best scores, and local statistics.

Numbered-game records

When you finish a numbered Minesweeper game, ClassicWorks sends the game number, difficulty, board-generator version, and completion time to its record API. The record database stores the fastest submitted time for that combination and the date the record was updated. It does not store your name, email address, local statistics, or the complete game board. Playing 2048 or Four in a Row does not submit a score, session, move, or statistic to this record service.

A slower completion does not replace an existing record. Record data is retained while the shared record feature operates, or until it is replaced or removed. The current system accepts completion times reported by the browser and should be treated as a lightweight community record rather than independently verified competition data.

Cloudflare hosting and aggregate measurements

ClassicWorks uses Cloudflare Pages, Pages Functions, and D1 to host the site and numbered-game records. Cloudflare processes the ordinary technical information needed to deliver and protect web requests, such as the requested URL, IP address, browser information, and security signals, under its own privacy terms.

Cloudflare provides aggregate measurements from requests handled at its edge. Cloudflare Web Analytics is enabled for aggregate page-visit and performance measurements using automatic setup. Its current configuration excludes visitor data in the EU, where Cloudflare does not inject the browser beacon. Cloudflare describes Web Analytics as cookie-free and says it does not track individual visitors across its customers' sites. Read the Cloudflare Privacy Policy for information about Cloudflare's processing.

Advertising

The game layout contains reserved advertising spaces, but ClassicWorks does not currently load an advertising network or advertising cookies. This policy and any required privacy controls will be updated before advertising or additional tracking technology is activated.
