The Sylo Smart Wallet is non-custodial, which means that users' funds are stored on the blockchain. As long as you have your secret phrase/private key, you will always be able to access your funds, whether it is through the Sylo Smart Wallet app or another digital wallet. 

If you deleted the Sylo Smart Wallet app or we ceased to exist, you would still have your assets. Holding on to your secret phrase/private key and keeping it secure is the key to always having access to your funds.
