Lamplit is a Mac app. Lamplit for Chrome is its Chrome extension. This page says what they read, where it goes, and what we never do. Updated 9 November 2026.
Only the page you are on, and only at the moment you press Keep or ask, or choose Keep in Lamplit from the right-click menu. Then it reads what you chose: the page as text, a part of it with its fonts and colours, a picture of what you see, the words you selected, or a post with who wrote it. It never reads a page on its own, never watches what you browse and keeps no history of where you went. It never clicks, types, posts, likes or sends anything.
What you keep goes to the Lamplit app on your own Mac, at a local address (127.0.0.1) only that Mac can reach, and is saved there as a file you own. It does not go to us. We run no server that receives what you keep.
When you drop or paste a link on the notch, Lamplit on your Mac reads that page from its own site, the way your browser would, so your agent gets the real words, and for a video its captions and chapters. It goes only to the address you handed it and that same site (a video page asks its own site for the captions); never to us, and never to any other service. You can turn this off in Settings › Privacy › Read links on this Mac; then the link goes to your agent as its address, and your agent fetches it.
When you ask your own AI agent (for example Claude Code or Codex) to work on something you kept, Lamplit hands it to that agent on your Mac, and the agent may send it to its own company (Anthropic, OpenAI) to do the work, under that company's terms. Keeping alone sends nothing to any agent.
When you keep from a site, Bun may ask Chrome's permission to read that site again later, so your agent can read a page there when you ask it to. You can forget any site on Bun's options page, and Chrome asks again next time. Your open tabs' titles are shared with your agent only if you turn that on.
No analytics, no tracking, no advertising, no selling or sharing of data, no accounts. The app checks this address about once a day for a new version of Lamplit; that request carries no information about you or your files.
Remove Bun from Chrome's extensions page at any time; what you kept stays in Lamplit on your Mac until you delete it there.
