Your funds are not stored in Phantom. Your balances and transaction history are recorded on the blockchain, and access to them is controlled by cryptographic keys that only you hold. Phantom stores those keys locally on your device and uses them to sign transactions on your behalf. You access them using your Secret Recovery Phrase, individual private keys, or a Google or Apple account.

Because your keys never leave your device, no one, including Phantom, can access or move your funds without them.
