Lanterna Grid · last updated 25 July 2026
Lanterna Grid is a single-player puzzle game. It has no accounts, no sign-in and no servers of its own.
What Lanterna Grid stores
Your puzzle progress, best times, saved boards and settings are stored in a database on your own device. This data is never transmitted anywhere. Deleting the app, or using Settings → Erase all progress, removes it.
Lanterna Grid does not ask for your name, email address, contacts, photos, location or any other personal information, and it contains no analytics, tracking or crash-reporting SDKs of its own.
Advertising
Lanterna Grid is free and supported by advertising through Google AdMob. To serve ads, the Google Mobile Ads SDK may process:
- device and advertising identifiers,
- approximate location derived from your IP address,
- ad interactions (views, clicks) and technical device information.
Where required by law (the EEA, the UK and other regulated regions) you are asked for consent before any personalised advertising is requested. If you decline, or if consent cannot be obtained, ads are served non-personalised. You can review or change those choices at any time via Settings → Ad privacy options.
Google's use of this data is described in Google's Privacy & Terms.
Ad content in Lanterna Grid is limited to a general-audience (G) content rating.
Children
Lanterna Grid is suitable for all ages and knowingly collects no personal information from anyone, including children.
