Tuhi runs on your Mac

Tuhi answers your questions on your Mac. When Apple Intelligence writes an answer, it uses Apple's on-device model, and everything else Tuhi does — understanding your question, finding the right help, choosing a screen — also happens on this Mac. Your questions and Tuhi's replies aren't sent to Storage Studio's servers or to Apple.

What Tuhi reads

To answer well, Tuhi reads things that are already on your Mac:

• Live storage facts — free space on your Mac and your external drive, whether automatic actions are paused, your schedule, memory and processor load, and your Mac's name, model and macOS version.
• Storage Studio's own records — what you've moved or offloaded, your backups, connected accounts and paired devices, recent background activity, and what's in the Recycle Vault.
• Where a file is — when you ask where something is, Tuhi looks it up with your Mac's own search.
• Help — Storage Studio's built-in answers and its help library, both stored on your Mac.

Tuhi doesn't open your documents to read what's inside them.

What stays on your Mac

• Your questions and Tuhi's answers. They're saved on this Mac so the conversation is there next time. Click the trash button in the conversation header (Clear conversation history) to delete it. Like Storage Studio's other records, the saved conversation is also included in the settings backups Storage Studio keeps on your own external drive, and clearing it doesn't change backups already made. See Backing up Storage Studio's own settings.
• What Tuhi learns about you. Tuhi keeps a small count of which suggestions it offered and which you used, so it can put the most useful ones first. It doesn't keep the words of your questions for this.
• Your conversation, even when you share logs. If you turn on diagnostic log sharing for support, your conversation with Tuhi is left out. Tuhi's entries in Storage Studio's logs note how long a question was, not what it said.

The few times Tuhi uses the internet

None of these send your question anywhere:

• Refreshing its help. At most once a day, Storage Studio downloads the latest public help pages — the same download for everyone.
• Downloading a link you give it. If you ask Tuhi to download a link, Storage Studio fetches that link into your Downloads folder.
• Support. If you ask to contact support, Tuhi opens a ticket form. Nothing is sent until you choose what to include and click send. See Getting help.
• "Learn more" links. Some answers end with a link to a help page. It opens in your web browser only if you click it.

Other assistants are different

If you turn on AI access so another AI assistant can read your storage status, that assistant follows its own privacy rules, and it may send what it reads to its own online service. Tuhi itself never does.
