Detect and kill zombie subscriptions, free trials, and hidden charges before they drain your wallet. Are you part of the average that loses $412 a year to subscriptions you don't even use? Sub-Zero isn't just a tracker -- it's an active defense system. Key Operations: The Kill Switch: Found a subscription you don't want? One click and our AI agent navigates the cancellation flow for you. No menus, no "Are you sure?" loops, no stress. Zombie Protection: We detect trial signups in real-time. We start a countdown. When it hits zero, we kill the trial so you don't get hit with that first $15, $50, or $100 charge. The Negotiator: Our agents chat with support bots 24/7 to find hidden discounts on your internet, phone, and streaming bills. Privacy First: We use 256-bit bank-level encryption. We never see your passwords, and we never sell your data. We only make money when you save money. Why install Sub-Zero? Because you shouldn't have to work a second job just to pay for apps you forgot you downloaded. Deploy your agent today.
