Contacts should be synced to a supported application on the computer or cloud service.
If you are really concerned about the possibility of losing contacts, use the device as designed.
Solely keeping contacts (or any important data) on a device that is easly lost/stolen, damaged, or destroyed like a portable device is simply not smart.
