Privacy Policy

Effective: 2026-05-07 · Last updated: 2026-05-13

Ki is a web browser for iPhone, made by Blake Crosley. This policy describes what data Ki collects from you. The short version: Ki collects nothing from you and sends nothing about you anywhere.

            Summary: Ki collects no personal data. There is no Ki account, no telemetry, no analytics SDK, and no advertising SDK. Bookmarks, history, tabs, and per-site permissions stay on your iPhone.
        

What Ki collects

Nothing about you, your device, or your behavior is collected, transmitted, or stored on a server we control.

There is no Ki account. There is no Ki backend. There is no analytics SDK, no crash-reporting SDK that captures content, no advertising SDK, no attribution SDK, and no third-party tracking SDK in the app. We have not embedded any code that reports your activity to us or to a partner.

What stays on your iPhone

Some information is stored only on your iPhone, in the app's protected sandbox, and is never transmitted to us:

Your bookmarks
Your browsing history
Open tabs
Per-site privacy decisions you make in the address-bar shield
Privacy profile preferences
Default search engine choice

If you delete the app, all of this data is removed by iOS along with the app.

Network traffic Ki initiates

Ki is a web browser, so it makes network requests that you direct it to make:

Web pages. When you navigate to a URL, Ki requests that URL. The request is sent directly from your iPhone to that website. We are not in the middle. The site you visit will see your IP address and any information their page collects, the same as in any other browser. Their privacy policy applies to that traffic.
Search. When you type a search query, Ki sends it to whatever search engine you have chosen in Settings. We are not in the middle. The search engine's privacy policy applies.
Optional Mac pairing. If you opt in to Mac pairing in Settings, your iPhone advertises itself on your local Wi-Fi network using Bonjour and accepts connections from a paired Mac running the Ki Mac-side tool. This traffic stays on your local network. It does not go to us. It does not go to the internet.
Optional bring-your-own-key (BYOK) AI providers. If you paste your own API key for a third-party AI provider in Settings, requests originated by features that use it go directly from your device to the provider you chose, using your key. We do not proxy or store the request, and we cannot read the key — it is held in your iPhone's Keychain. The provider's privacy policy applies to that traffic.

Permissions Ki may request

Ki uses the iPhone's standard permission prompts when, and only when, the page you are browsing needs them, and only when you have first enabled that permission for that site through the address-bar shield. We currently use:

Local Network. Requested only if you opt in to Mac pairing in Settings. Used to advertise the iPhone over Bonjour on your local Wi-Fi.
Camera. Requested only when a web page calls getUserMedia for video AND you have enabled Camera for that site in the address-bar shield. Default is block, so the iOS prompt does not appear until you explicitly enable the toggle. Flipping the toggle off while a camera stream is active immediately stops the stream.
Microphone. Same posture as Camera, for getUserMedia audio requests.

Permission requests come from web pages, not from Ki itself. Ki gates each request based on your per-site policy in the shield.

Ki does not request the following: Location, Contacts, Photos, HealthKit, Bluetooth, Motion, Reminders, Calendar, or the iOS advertising identifier (IDFA).

AI assistance

Ki has an on-device assistant you reach by long-pressing the URL bar. It plans the next browser action based on the goal you typed and a small snapshot of the current page (URL, title, visible elements). Where that information goes depends on which "brain" you pick in Settings → Assistant brain:

Apple Intelligence (default on supported iPhones). Runs on this iPhone. Nothing is sent off-device. The Apple Foundation Models framework processes your prompt locally.
Anthropic / OpenAI / a custom OpenAI-compatible host (BYOK). You paste your own API key in Settings. The first time you use the brain Ki shows a consent modal naming the exact destination (e.g. api.anthropic.com) and what is sent. Traffic goes directly from your iPhone to the provider you chose, using your key. Ki does not proxy, log, or store the request body. The provider's privacy policy applies. You can revoke consent any time in Settings → Assistant brain.
Paired Mac. If you've paired a Mac via the optional Mac companion, you can let it act as the brain. Traffic stays on your local Wi-Fi between the iPhone and the paired Mac — never to the internet.

In every case, only your typed prompt, the current page's URL + title, a compact list of visible elements (selectors + labels), and the running action history are sent. No cookies, no browsing history, no full DOM, and no Keychain keys other than the one you provided. Per-brain consent state is stored locally on your iPhone.

Cookies and trackers in the browser itself

Ki blocks known cross-site trackers by default using iOS's built-in content-blocker mechanism (WKContentRuleList). You can adjust the policy per site by tapping the shield icon in the address bar.

Cookies a site sets are stored in the system web view's data store, scoped to that site, and isolated to the privacy profile you are using. You can clear them at any time from Settings.

Data we sell or share

None. We have no data to sell, because we collect none.

Children

Ki is rated 17+ on the App Store because it offers unrestricted access to the web. It is not intended for users under 17.

Changes to this policy

If this policy changes, the "Last updated" date at the top will change and the new version will be published at this URL.
