Privacy Policy

Last updated: August 29, 2026 — applies to version 1.2.0 and later.

What the extension reads

When you open the popup, the extension reads the following information about your currently open tabs, using Chrome's/Firefox's/Safari's built-in tabs permission:

• URL and page title
• Tab position (index) and window ID
• Tab ID and the ID of the tab that opened it, if applicable
• Numeric tab group ID, if the tab is part of a group
• Last-accessed timestamp
• Whether the tab belongs to an incognito/private window

Each of these fields only appears in the extension's output if you explicitly check its corresponding option in the popup. With every option unchecked, only the URL is included.

What the extension does with that data

It formats the data you asked for (as plain text, Markdown, JSON, CSV, or TSV) and copies it to your clipboard when you click "Copy." That's it. The data is held in memory only, for as long as the popup is open, and is discarded — not stored, not cached, not written to disk — the moment the popup closes.

What the extension does not do

• No network requests of any kind — the extension has no server to send data to, and doesn't talk to one
• No analytics, telemetry, or crash reporting
• No cookies, no storage permission, nothing persisted between sessions
• No host_permissions — the extension cannot read the content of any web page
• No background service worker — it only runs while its popup is open
• No third-party or CDN-hosted scripts
• No accounts, sign-in, or user identifiers of any kind

Permissions

The extension requests exactly one permission: tabs. This is required to read the list of open tabs described above. No other permission is requested on any supported browser (Chrome, Firefox, or Safari).

Open source

The full source code is public and MIT-licensed, so this policy can be verified directly against the code rather than taken on faith: github.com/muminkoykiran/safe-tab-url-lister.

Changes to this policy

If this policy ever changes, the "Last updated" date above will change and the update will be noted in the project's changelog.

Questions about this policy or the extension's data handling can be raised as a GitHub issue, or privately via GitHub's private vulnerability reporting for security-sensitive matters.
