Mecha-Ku is a free browser game operated by Extended Study, LLC. Core puzzles run in your browser. Optional advertising supports free access.
We store game progress locally (e.g. high scores, settings) using browser storage such as localStorage. This data stays on your device unless you clear site data.
If ads are enabled, third parties (for example Google AdSense or similar networks) may use cookies or advertising IDs to deliver and measure ads, prevent fraud, and (where allowed) personalize ads. See Google’s policies: policies.google.com/privacy.
You can use browser controls, Google Ad Settings, or our consent banner (where shown) to limit non-essential ads.
When live ad units are connected, this policy may be reviewed again for network-specific disclosures; no other changes are expected solely from enabling ads if the practices above still apply.
You do not create a Mecha-Ku account to play the web version.
The game is intended for a general audience. Configure ad networks appropriately for your audience; we do not knowingly collect personal information from children for our own profiles.
Questions about this policy or the web game: see Support or email mechasquare-support@gmail.com.
