Siftlume privacy policy

Last updated: November 8, 2026

Siftlume is a browser extension that summarizes the page you are reading, text you paste, or a file you choose, using an AI provider that you configure with your own API key. Siftlume has no server of its own. This page explains what data the extension handles and where it goes.

Summary

Siftlume does not collect, sell or share your data, and it has no analytics or tracking.
Content is sent only to the AI provider you configured, and only when you ask for a summary or ask a question.
Your API keys, settings and history stay in your browser.

What Siftlume handles

Data	When	Where it goes
Text of the page you summarize (or the selection, pasted text, or file)	Only when you click Summarize, use the context menu, refine a summary or ask a question	Sent directly from your browser to the AI provider you selected (for example OpenAI, Anthropic, Google, OpenRouter, or a local server such as Ollama). Not sent anywhere else.
Your questions about the content	When you ask them	Sent to the same AI provider, together with the content they refer to.
API keys and settings	When you save Settings	Stored only in your browser (`chrome.storage.local`). Never synced to your Google account and never sent anywhere except as authentication to the provider you selected.
Summary history	After each summary	Stored only in your browser (`chrome.storage.local`). You can delete items at any time; uninstalling the extension removes them.

Siftlume does not read pages in the background. It reads a page only after you click the extension icon or use its context menu on that page.

Third-party AI providers

When you summarize content, it is processed by the AI provider you chose, under that provider’s own terms and privacy policy. Review your provider’s policies to understand how they handle requests. If you use a local model (for example Ollama or LM Studio), the content never leaves your computer.

Permissions

Permission	Why Siftlume needs it
`activeTab`, `scripting`	Read the text of the tab where you clicked the icon or used the context menu, and highlight a quoted passage in it when you ask.
`sidePanel`	Show summaries in the side panel next to the page.
`contextMenus`	Add “Summarize this page” and “Summarize selection” to the right-click menu.
`storage`, `unlimitedStorage`	Keep your settings and summary history in your browser, including data from CSV files you summarize.
`declarativeNetRequestWithHostAccess`	Let requests from the extension reach a local AI server (such as Ollama) that would otherwise reject the extension’s origin. It only applies to the extension’s own requests to servers you granted.
`favicon`	Show the website’s icon next to a summary.
`clipboardWrite`	Copy a summary or a quote when you click Copy.
Optional host access	Requested only when you save Settings, for the domain of the AI provider you configured, so the extension can call its API.

Children

Siftlume is not directed to children under 13 and does not knowingly collect information from them.

Changes

If this policy changes, the new version will be published at this address with a new date.
