What the game does
A lantern slides back and forth above your growing tower. You tap to drop it, trying to keep each new layer aligned with the one below. Overhanging portions get trimmed away, and the tower topples if a drop misses entirely.
Data involved
Your tower's best height is saved in your browser's local storage under a single key, purely so it persists between visits on the same device. This value never travels to any server — it's handled entirely within your browser.
- Your personal best tower height, stored only in your browser
- Standard web server access logs (timestamp, browser type) used to keep the page running and secure
What's deliberately absent
No accounts, no names, no contact details, no location tracking. We haven't wired in any advertising network or third-party analytics provider — there's nothing here that benefits from knowing who's building the tower.
Cookies
StackLantern does not use cookies. The local storage entry behaves differently from a cookie: it never gets sent to a server automatically and stays on your device until you clear it yourself.
Server logs
As with most web pages, our hosting setup keeps brief routine logs to catch abuse and keep things running smoothly. These aren't tied to individual visitors in any meaningful way and are cycled out after a short period.
Sharing
There's no data-sharing arrangement with advertisers or third parties connected to this game, because there's essentially nothing personal to share in the first place.
Your control
You can erase your saved best height at any time by clearing this page's site data through your browser's settings. Doing so simply resets the number back to zero.
Updates
If StackLantern's approach to data ever changes, this notice will be updated to reflect exactly what's different and why.
