Does Mac Ninja close my apps or tabs?

Mac Ninja never closes your apps. Idle browser tabs are unloaded but stay in your tab bar and reload instantly when clicked. Background apps simply get lower priority but keep running. With the free Chrome helper, it closes only tabs that AI agents like Claude opened and then abandoned for 8 hours.

Will it really make my slow Mac faster?

Mac Ninja targets the most common causes of slowness: many browser tabs and background apps hogging resources. It works if your Mac slows down because of these factors. It cannot speed up an old processor and packs away unused apps rather than photos and videos when disk is full. There is a 7-day free trial to test it on your own Mac.

Is it a subscription?

No, you have a choice. The yearly plan costs $9.99/year and you can cancel anytime. The lifetime plan costs $24.99 one-time and includes all future updates. Both plans include every feature and work on up to 3 Macs.

Mac Ninja only uses standard macOS and browser features such as the browser's own tab unloading and macOS's low-priority lane used by Time Machine and Spotlight. It requires no kernel extensions, system file changes, or admin password for normal use.

What happens if I cancel the yearly plan?

Mac Ninja keeps working until the end of the year you paid for, then switches itself off. Your apps aren't affected. You can cancel, update your card or see receipts anytime at app.link.com, and you can switch to Lifetime whenever you like.
