In the apps
The apps create transfer information on your devices; they do not send it to us. They periodically clean up temporary data, while saved files and some local records may remain until you remove them. Uninstalling may leave files or local keys behind. You can revoke file access in your device settings; we cannot delete anything from your devices remotely. Apple handles Mac purchases, so we do not receive your payment-card details. Files in your own cloud services follow those services' settings.
