If you unpair your device from the Monolith app your private key will be removed and you will no longer have access to your Contract Wallet. Please keep a backup of your Seed somewhere safe (not on your device, in case your device is lost or stolen).
You will need your Seed to reactivate both your Monolith account and your Contract Wallet.
Monolith never sees your Seed, or keeps a copy of it, therefore we will not be able to assist if you lose it.
