Your puzzles stay close to home

Last updated: 15 October 2026. GridMew provides browser-based logic puzzles. Core play does not require an account, paid API or cloud game storage. This page describes this version’s actual data paths; optional analytics and advertising are off.

Local progress and settings

GridMew uses this browser’s localStorage for the current practice and daily games, cat placements, × notes, active play time, hint use, completed records, lesson-reading flags, and display/control preferences. The data stays in this browser and is not synchronized to another device or browser.

Use My progress to export a JSON backup, import compatible records or clear progress. Clear progress keeps display and control settings; Restore default settings keeps puzzle history. Clearing browser site data can remove both. If storage is blocked or full, play can continue without reliable saving. Backups remain files on your device until you choose to share them.

Screenshots and custom boards

A screenshot you choose is decoded and sampled in this browser. The image, crop, extracted regions and custom board are not uploaded, added to a URL or sent to analytics. Cats and × marks are checked and added manually. Image buffers are released when you leave the workflow; a custom board is temporary and is not a cloud save.

Solving runs in a browser computation thread. This is local device work, not a Cloudflare server function. The site limits images to PNG/JPEG/WebP, 10 MiB and 20 million decoded pixels. Do not rely on this workflow as an archive of a file or custom board.

Hosting and ordinary requests

Loading GridMew requests static pages and assets from its hosting provider, Cloudflare. As with ordinary web hosting, the provider can receive request information such as IP address, requested path, browser headers and request time to deliver and protect the service. This is separate from GridMew uploading game positions or screenshot contents.

See Cloudflare’s privacy policy for the provider’s practices. We do not claim to control the provider’s own retention settings or policies.

Optional services and external links

No analytics beacon, GA4 tag, advertising script or third-party font loads in this release. Optional analytics or advertising require later service configuration, a matching privacy update and consent setup before activation. Core play must remain available without them.

External links navigate to another provider when you choose to open them. Emailing hello@gridmew.com sends the information you choose through your mail provider to the contact mailbox. The local screenshot workflow itself does not send email.

Your choices and contact

You can export or clear progress in My progress and change preferences in Settings. For a question about this page or information you intentionally emailed, contact hello@gridmew.com. Please identify the relevant message without sending unnecessary sensitive information.
