Built for the
Money Leak

The average person has 7+ active subscriptions but only consciously remembers 3. The gap — forgotten trials, silent price hikes, annual plans you meant to cancel — costs real money, month after month.

NinjaX was built to close that gap. Your financial data stays on-device, encrypted with SQLCipher. No account required. No server ever sees your subscription list.

When it's time to cut, our AI writes the email — professional, firm, sent from your own inbox. The service has to comply.

Stay stealthy. Save money. Go ninja.
