Privacy notice

Puzzle progress

The game stores your puzzle, moves and preferences in the app on your device. We do not receive your puzzle boards or provide cloud accounts or cloud saves. Clearing the app's data or uninstalling it removes that local progress.

Advertising and privacy choices

The Android build includes Google's Mobile Ads and User Messaging Platform SDKs. When advertising is activated, Google may collect and share IP addresses (which can indicate approximate location), app and ad interactions, diagnostic information, advertising IDs, app set IDs and other applicable device or account identifiers. Google uses this information for advertising, analytics and fraud prevention and encrypts it in transit.

Where required, the app presents Google's consent choices before requesting ads. A Privacy choices entry is shown when Google requires it, so you can revisit your selection. Android also provides controls for resetting or deleting your advertising ID. Choosing Ad concern in the game pauses further ad requests on that device; an optional email is sent only if you choose to send it.

Google's handling and retention of its data are described in its Privacy Policy and information about partner apps. We do not have access to an individual player's advertising identifier through the game.

Support messages

If you email us, we receive your address, message and any attachments you choose to send. We use them to answer your request and investigate the issue, and retain them as needed for that purpose. Email is handled through Proton Mail. Do not include sensitive personal information that is unnecessary for your request.

To request access to or deletion of support information you sent, email independentworkflowlab@proton.me. Local game data can be removed through Android's app storage settings. Requests concerning data controlled by Google should also be directed to Google.

This website

This website has no sign-up form, advertising, analytics script or purchase flow added by Independent Workflow Lab. Its hosting providers process ordinary request information, such as IP addresses and browser details, to deliver and protect the service.

Audience and changes

The Android release is intended for adult puzzle players and is not directed to children. We do not knowingly ask children to submit personal information. Contact us if you believe a child has sent information to us.

We will update this notice when the app's data practices change. The date above identifies the current version.
