FAQ
Short answers for the obvious questions.
Will it accidentally delete or overwrite something?
Never. Stark has a zero-deletion policy — it only moves files. Every single move is logged with source and destination, so you can reverse anything with one click.
Does my data leave my Mac?
No. There's no server, no cloud sync, no account. Everything runs locally using on-device AI. Your files never leave your machine.
What happens to my Git repos and Xcode projects?
They're automatically protected. Stark detects .git, node_modules, Pods, .xcodeproj, Cargo.toml and other project markers, and excludes those folders from any operation.
Can I undo an entire session?
Yes. Stark logs every batch as a separate session in the History view. You can undo a single session or roll back multiple sessions at once with "Undo to Here".
Is the $14.99 really a one-time price?
Yes. Pay once through the Mac App Store and own Stark Pro forever. No renewals, no hidden fees, no subscription.
Does it work on older macOS versions?
Stark requires macOS 26.0 or later. The full AI pipeline uses Apple Foundation Models which is available on macOS 26+.
