Description from store
Previewer.app Tooltip is a lightweight, privacy-respecting browser extension that helps you explore the web more safely and efficiently. When you hover over a link that points outside the current website, the extension shows you a quick preview of the destination - so you can decide whether it’s worth clicking.
Perfect for everyday browsing or simply avoiding sketchy or misleading links.
How It Works
When you hover over an external link, the extension sends a request to our secure proxy server. That server fetches the destination page, follows redirects, extracts key metadata (like title, description, thumbnail, and social media preview tags), and returns a compact preview back to your browser - all within a styled tooltip.
Under the Hood
Redirects followed: You’ll see the final destination, not just the raw href.
Global caching: URLs are hashed and previews are cached for 7 days. If someone has recently previewed the same link, you’ll get the result instantly from cache.
Sanitized previews: We clean and normalize all returned data.
No background crawling: We only fetch a page when you hover over a real link.
Privacy by Design
Removes common tracking parameters from URLs
Doesn’t access or store your browser history
Doesn’t open or request any link you haven’t explicitly hovered
All previews are fetched anonymously and securely via our proxy
We do not collect any personally identifiable information (PII)
The extension requires access to all sites you visit in order to detect links on the page - but no content or browsing data ever leaves your browser.

We strongly encourage all users to read our Privacy Policy and Terms of Use before installing the extension, to fully understand how it works and what to expect.
