Privacy and safety

Saiki has no account and no server of its own: what you search, copy and say stays on your Mac, and anything that deletes or changes things asks you first and can be undone.

This page is the detail for the app. The short version, which also covers the website, is Saiki's privacy policy.

What stays on your Mac

What goes over the network

Only these, and each belongs to a feature you can turn off:

WhatWhen, and where it goes
Web search suggestionsOnly in web search mode (search then ⇥): what you type goes to your search engine for suggestions. Turn off Settings → Search → Web search suggestions to stop it.
Exchange ratesWith the Calculator on, Saiki downloads current rates about every 6 hours from Coinbase and checks them against the European Central Bank. Nothing you type is sent.
Site iconsFor a site search shortcut whose icon Chrome doesn't have, Saiki fetches the icon once from that site itself, never from an icon service.
Dictation modelsDownloaded once, the first time you dictate or when you pick a model in Settings → Dictation. Each download is checked against a fixed fingerprint before it's used.
AIYour questions go through your own claude or codex tool to Anthropic or OpenAI, under your own plan. With AI on, Saiki also checks whether a newer Claude Code is out. See Set up AI.
Saiki updatesOnce a day Saiki asks GitHub, where its releases are, whether there's a new version. Nothing installs until you choose to. Turn off Settings → About → Check for updates automatically to stop it. See Updates.
App UpdatesHomebrew apps are checked with Homebrew on your Mac. Only if you turn them on: App Store apps are checked against Apple's lookup, which sends Apple the ids of those apps, and other apps against their developers' own update feeds and then Homebrew's public catalog (formulae.brew.sh), so each developer learns you have their app. See App Updates.
HomebrewThe commands you run (search, install, update) reach Homebrew's servers, as they do in Terminal. Search results are sorted by Homebrew's public install counts from formulae.brew.sh; turn off Show how popular search results are to stop that. Nothing about you is sent. See Homebrew.
Network Speed TestOnly when you run it: macOS's own networkQuality test against Apple's servers. See Monitors.

Turning a feature off in Settings stops all of its work, network included.

Clipboard History

Clipboard History is built to keep passwords and secrets out. See Clipboard History for the rest of it.

When Saiki pastes something of its own into another app (an emoji, an AI answer, a calculator result), it puts your own clipboard back right after, unless you've copied something new in the meantime. What you type for the developer text tools is never stored.

Nothing changes without you
