Privacy and browser storage

Data stored in this browser

The site can retain your selected language, compact targets from the previous random round to avoid near-repeats, and completed Daily or Archive scores. Random practice scores do not overwrite dated records.

These records belong to this website address and browser profile. Another device or address has separate storage. Clearing site data, private browsing or a browser restriction may remove or prevent saved information.

Audio and page loading

Tempo generates sound through browser audio and measures your input timing. It does not record sound or request microphone access. The game has no sign-in, cloud synchronization or advertising.

The browser requests pages and files from the server that hosts this website. Gameplay and score calculation run in the browser, and dated results are stored on the device.

Usage measurement and links to MellowCade

Usage analytics is disabled in this version. It does not send page-view or game-usage events to Vercel Web Analytics.

The language settings, previous random targets and dated results described above can still be stored in this browser. Disabling analytics does not remove those local records.

The link parameters do not contain your answers, puzzle seeds or scores. Once you open MellowCade, its own privacy information applies to your visit there.
