Your ball stays
on your Mac.

No account or telemetry

Tether does not create an account, send analytics, display advertising or upload your activity.

Local settings only

Your selected ball, physics settings and lifetime bounce count are stored locally using macOS preferences.

Window geometry

When “Land on windows” is enabled, Tether reads the position and size of visible windows so the ball can use stationary windows as surfaces. Window titles and contents are not collected or stored.

Screen sharing

When “Invisible on screen share” is enabled, Tether asks macOS to exclude its overlay and settings panel from supported captures. Tether does not inspect or record your screen.

Optional feedback submissions

If you deliberately submit the feature-request form, its category, message and any email address you choose to provide are sent through Formspree to PaperCloud Studios. This information is used only to read and respond to your request or improve Tether. Nothing is submitted in the background, and the form is not used for tracking, advertising or analytics.
