Upon start of the ParcelTrack application any data contained on the global pasteboard (iOS) or clipboard (Android) will be sent to Parcel Track’s servers.
Sensitive PII such as credit card numbers and passwords often live on the global pasteboard. If any sensitive data is contained on the pasteboard when a user starts the ParcelTrack app this data would sent to ParcelTrack’s servers.
On start of the ParcelTrack application the app will grab any data contained on the global pasteboard/clipboard and send it in an HTTP GET request to ParcelTrack’s server.
Consider not sending any pasteboard to ParcelTrack’s servers. If the pasteboard is needed, then provide users with the ability to deny the ParcelTrack app access to data on their clipboard. If clipboard access is granted, implement functionality that determines what type of carrier is contained on the pasteboard on the device before sending to ParcelTrack’s servers.
