What we store

This website stores one thing on your device. That’s it.

Your preferences: twistcal.preferences (localStorage)

When you pick a theme (Light / Dark / System) or toggle High Contrast mode, we save your choice to your browser’s localStorage under the key twistcal.preferences. This data never leaves your device. No server ever sees it.

What we don’t do

  • No analytics, tracking scripts, or telemetry.
  • No third-party cookies, pixels, or beacons.
  • Nothing sent to any server, and no account required.
  • No personal data collected.

The playground

The playground at /play/ runs TwistCal locally — it’s bundled with the site, no third-party requests. All configuration happens in your browser. No data is sent to any server.
