Privacy Policy

Effective July 14, 2026

Lochan collects nothing. There are no accounts, no analytics, no tracking, and no advertising identifiers. Lochan runs AI models directly on your iPhone and iPad, and your conversations stay on your device by default.

What stays on your device

Your conversations, your settings, and any models you download live only on your device. We never receive them, and there is no Lochan account or server that stores them. Chat with Apple's on-device model or a downloaded open model does not send your messages to Lochan or to any third-party AI service.

What touches the network, and only when you act

• Sharing a conversation. If you choose Share as link, Lochan shows what will be included (message text, timestamps, model names, and any images or files in the share), names the recipient service (share.lochan.app), and only uploads after you tap Create link. Content is encrypted on your device before it leaves. The share service stores only encrypted data that we cannot read. The decryption key travels in the link fragment and never reaches our server. Links expire automatically (within about an hour). Nothing is shared unless you initiate it and confirm.
• Web Search. Optional. If you enter your own Brave Search API key and turn on Web Search for a message (after an in-app permission that explains this), search queries derived from that chat are sent to Brave Search (api.search.brave.com) using your key. Your conversation otherwise stays on device. Lochan does not receive those queries.
• Downloading models or voice assets. When you choose to download an open model or the read-aloud voice pack, that download comes from the model's host or our CDN. This is a normal file download and involves no Lochan account and no upload of your chat content.

No analytics or tracking

Lochan contains no third-party analytics, advertising SDKs, tracking pixels, or usage telemetry. We do not build a profile of you because we do not receive any data about you.

Third parties

When you use an optional network feature above, data goes only to the party named in the app at the moment you grant permission (Brave Search for web search queries; share.lochan.app for encrypted share payloads). Those parties process the data under their own terms for the purpose of providing the service you requested. Lochan does not sell personal data and does not use third-party AI services for default chat.

Children's privacy

Lochan does not collect personal information from anyone, including children. Because there is no account and no data collection by Lochan, there is nothing for us to gather regardless of a user's age.

Changes to this policy

If this policy changes, we will update this page and revise the effective date above.
