There is no account, no login and no server that stores anything about you. Your puzzle progress is saved in your own browser and never leaves your device. If ads are running, the ad provider sets cookies and sees your IP address — and you can decline that and still play the entire game.
The game uses your browser's local storage — not cookies — to remember:
This never leaves your browser and is not transmitted anywhere. Clearing your browser data removes it, and the Reset saved progress button in the footer of the game deletes it on demand.
This game is free and always will be. There is nothing to buy, no premium version and no paywall. It may carry advertising to cover its costs.
When ads are enabled, an advertising provider's code runs in your browser. That provider may set or read cookies and similar identifiers, and necessarily receives your IP address, approximate location, device and browser details, and which pages you viewed, in order to select and measure ads. Depending on which provider is active, that is Google and its advertising partners, or GameMonetize and theirs. Their own privacy policies govern what they do with it.
You can say no. Choosing "No ads" when asked means no advertising code is ever loaded, and the game — including every level and every hint — works exactly the same. That choice is remembered in your browser.
You can also opt out of personalised advertising generally at Google My Ad Center or optout.aboutads.info.
The site is served as static files. The host processes standard web-server information — your IP address, the time of the request, the page requested, your user agent — to deliver the page and to protect the site from abuse. No analytics or tracking scripts are used.
This game is suitable for all ages, but it is not directed at children under 13 and no information is knowingly collected from them. If ads are shown, the provider is instructed to serve only ads appropriate for a general audience where that setting is available.
Because nothing about you is stored on any server here, there is no account to access, correct or delete — clearing your browser data removes everything this site holds. For data the advertising provider may hold, contact them using the links above, or write to us and we will point you in the right direction.
If this policy changes materially, the date below changes with it. Ads being switched on or off, or the provider changing, counts as material.
