When people ask if a trading tool is “safe,” the deepest concern is usually about their money. NoVo's most important safety feature is structural: it's non-custodial — it never holds, touches, or has access to withdraw your funds. That single fact removes the biggest risk in the whole category.
How non-custodial works
Your money stays in your own broker account (Tradier or Alpaca) — a regulated brokerage you opened and control. NoVo connects to it through a broker API with permission only to place trades on your behalf, not to move money out. There's no NoVo wallet, no deposit to NoVo, no pooling of customer funds. The tool can trade in your account; it cannot withdraw from it. This is the opposite of the custodial arrangements where you hand your money to a third party and hope.
Why this matters so much
The catastrophic failures in this space almost always involve custody — a service that holds your funds absconds, gets hacked at the wallet level, or freezes withdrawals. Non-custody makes that class of disaster structurally impossible: there's no pot of your money for anyone to take, because it never leaves your broker. Your worst case with NoVo is the normal trading risk (you can lose money on trades) plus the tool not working — not losing your capital to a custody failure.
The safest place for your money is somewhere a tool can't take it. Non-custodial means your funds never leave your own regulated broker — NoVo can trade, never withdraw.
The other layers of safety
Beyond custody: you set the risk boundaries NoVo can't trade outside of, a protective stop protects each position, and you can revoke the broker connection at any time. On the security side, see can NoVo be hacked for how the non-custodial model limits the damage even in a worst case. “Safe” is never absolute in trading — you can still lose money on trades — but on the dimension that ruins people, non-custody is the right architecture.
