While Play counts is on, Droplis counts:

• that the game opened, and your furthest level
• how many new or made over levels an update brought you
• levels started, cleared, cleared with a hint, or missed, with the stars and how many Droplis popped
• hints, and the daily board
• the size of your screen
• whether the sound started
• that the game hit an error, and where in its code
• on an iPhone or iPad in a browser: when the game said it is an app, and a tap on the App Store badge
• in the playable Droplis square on other websites, which has no settings: a board shown, its first tap, a board cleared, the last card, and a tap on its button

Each count is a name, a few small numbers and one word for where the visit came from, such as the website that linked here. No cookies, no ID, nothing that tells players apart. Cloudflare delivers the counts, like every page of this site, and they are never linked to you.

Your progress stays on this device. Turn the switch off and counting stops at once.
