Frequently asked
Does SpinCat send my data anywhere?
No. System metrics are read with local macOS APIs and never leave your Mac. The only network access is the optional AI usage feature, which stays off until you enable it.
Why a cat?
Because a spinning cat is a friendlier load gauge than a number. When your Mac is calm, the cat rests; when it's working hard, it spins fast — you feel the state without reading anything.
Does it slow down my Mac?
SpinCat samples on a light interval (three seconds by default), caches expensive reads, respects Reduce Motion, and eases the animation under thermal pressure.
Which AI providers are supported?
ChatGPT, Claude, Cursor, Antigravity, and Copilot. AI usage is opt-in, per provider, and never required.
Is it accessible?
Yes. The interface is fully keyboard navigable and every slider, stepper, picker, and status value carries a VoiceOver label.
