Privacy
Nothing leaves your Mac.
Notchjack is designed to work without an account, a server, or a network connection.
Effective July 28, 2026
No data collection
Notchjack does not collect analytics, telemetry, identifiers, gameplay history, or personal information.
No network access
The app does not make network requests. There is no cloud service, advertising service, or third-party analytics service attached to gameplay.
Local app data
App Preferences, Presets, Session Saves, Counting Practice progress, and optional custom card-back artwork are stored locally in Notchjack’s sandboxed app container. This information is used only to provide app features on your Mac.
Retention and deletion
Local data remains on your Mac until you remove it. Notchjack lets you end a saved Session, delete Presets, and remove custom card-back artwork from within the app. For help locating or removing any remaining local app data, use the support page.
This website
This marketing site does not require an account and does not use advertising trackers. If hosting-level operational logs are enabled by the hosting provider, they are used only to operate and secure the site.
Updates
If the app’s data practices change, this page will be updated before the change applies.
