Data stored on your device
Official daily scores, practice runs, streak history, personal bests, recent standalone-test results and sound preferences are stored in your browser using local storage. They are not automatically transmitted to a Human Precision server. Clearing browser data can remove them.
Sharing and backups
Share buttons create a casual challenge link containing the score and result type. They do not include your name or complete score history. Exporting progress downloads a JSON file to your device. Importing a backup replaces the local Human Precision progress file on that browser.
Analytics
No analytics service is included in this source package. Before adding analytics, disclose the provider, events collected, retention period and available consent controls.
Advertising and cookies
No advertising positions or ad-network code are active in this launch package. Before activation, update this policy to explain third-party cookies, device identifiers, IP-address processing, personalized-ad choices and regional consent requirements.
Your choices
Use the Progress page to export, import or delete Human Precision progress. You can also clear site data through browser settings. Progress does not automatically follow you to another browser or device.
