Unfold
Privacy Policy
Unfold is a browser extension that helps you get an AI summary of the article you're reading. This policy explains what it reads, what it stores and what it shares.
- Unfold has no server, no account and no analytics or tracking.
- Unfold never sells your data and never uses it for advertising.
- Page information leaves your browser only when you click an AI button, and only goes to the AI service you picked.
What Unfold reads
On pages that look like articles, Unfold reads the following in your browser:
- the page title, description, section (breadcrumb) and URL
- the article text, to estimate reading time, to build Markdown when you use Copy page or View as Markdown, and (only if you turn on Include article text) to include it in the prompt
Unfold doesn't read form fields, passwords, cookies, your browsing history or other tabs.
What Unfold shares, and with whom
When you click an AI button, Unfold opens that service in a new tab with a prompt about the page. The prompt contains the title, section, description and URL, and the article text if you turned that option on. That service's own privacy policy then applies:
- ChatGPT (OpenAI): openai.com/policies/privacy-policy
- Claude (Anthropic): anthropic.com/legal/privacy
- Gemini (Google): policies.google.com/privacy
- Perplexity: perplexity.ai/hub/legal/privacy-policy
- Grok (xAI): x.ai/legal/privacy-policy
Unfold doesn't send data to any other party, including its developer.
What Unfold stores
- Settings (on/off, position, sites you turned it off on, which AI buttons to show, and the "Include article text" option) are saved in your browser's extension storage. If browser sync is on, your browser syncs them across your devices.
- Temporary data: for Gemini, the prompt is kept in local extension storage for up to a minute so it can be typed into Gemini. For View as Markdown, the page's Markdown is kept in session storage until the viewer tab opens. Session storage is cleared when you close the browser.
Removing the extension deletes all of this.
Permissions
- Access to websites: to detect articles and show the summary box.
- Storage: to save your settings.
- Clipboard write: for Copy page, and to copy the Gemini prompt.
- Active tab: so the toolbar popup can show and toggle the current site.
Changes and contact
If this policy changes, the new version will be posted on this page with a new effective date.
