Supplies does not collect any data about you or how you use the app.
If you have chosen to share analytics about your app usage with developers, some limited information (e.g. how often you use Supplies) will be collected by Apple. You can opt in or out of that at any time from the Settings app on your device.
Your app settings, checklists and any custom statuses or locations you create are stored on your device and optionally synced to iCloud. Data regarding your supplies and shopping list items is stored in Reminders lists that are synced to iCloud. You can inspect these lists and what kind of information is stored there at any time via the Reminders app.
