TL;DR Peek — Privacy Policy

Last updated: 20 August 2026

TL;DR Peek is a Chrome extension that previews a link’s article when you hover it. This policy describes what it does with data. The short version: it collects nothing, sends nothing anywhere, and has no server.

What the extension stores

On your own machine only, via Chrome’s extension storage:

  • the list of domains where you have switched previews on
  • your preferences: hover delay, summary length, description length, thumbnail on/off, Alt-only mode, and the master switch

If you are signed into Chrome, Chrome may sync these settings between your own devices using your Google account, exactly as it does for your bookmarks. The developer has no access to them.

Nothing else is stored. The extension keeps no history of the pages you visit or the links you hover.

What the extension requests from the network

When you hover a link on a site you have enabled, the extension makes a single anonymous GET request to that link’s URL — the same request your browser would make if you clicked it, with these restrictions:

  • it is sent from your browser directly to that website; it does not pass through any server belonging to the developer, because none exists
  • no cookies or credentials are sent (credentials: 'omit'), so the site sees an anonymous visitor and cannot connect the request to your account there
  • at most the first 1 MB of the page’s HTML is read, then the transfer is cancelled
  • the response is used only to build the balloon shown at that moment

The page’s description and text are processed entirely inside the extension on your computer. Summaries are produced locally by bundled code (Mozilla’s Readability, Apache-2.0, plus a sentence-ranking summarizer). No artificial-intelligence service, API, or third party is involved.

Results are cached in memory for 30 minutes so that re-hovering the same link is instant. The cache is discarded when the browser closes or when you press Clear cache in the popup.

What is not collected

The extension does not collect, transmit, sell, or share:

  • personally identifiable information
  • authentication information, passwords, or credentials
  • financial or payment information
  • health information
  • personal communications
  • location data
  • browsing history or web activity
  • website content

There is no analytics, telemetry, crash reporting, advertising, or tracking of any kind in this extension.

Where previews are active

Previews are off by default on every site. They run only on domains you switch on yourself in the extension’s popup, and only while the master switch is on. Turning a domain off, or using the master switch, stops all requests immediately.

Permissions and why they exist

  • Storage — to remember your settings and your list of enabled domains.
  • Access to websites you visit (http://*/*, https://*/*) — a link on any site can point to any other site, so the extension cannot know in advance which host it will need to read. This permission is used solely to fetch a page you hovered, on a site you enabled.
  • Offscreen — the extension creates a hidden document to parse fetched HTML, because summarising requires a DOM and Chrome’s extension service workers do not have one. It displays nothing and cannot see your tabs.

Children

The extension is not directed at children and collects no data from anyone.

Changes

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