When it does anything

The extension is request scoped. It reads the one product page you invoke it on, and invoked means you clicked its button on that page. There is no background collection, no page load beacon and no browsing history. Closing the popup ends it.

What leaves your browser

Sent to our server

  • the shop's origin, meaning https://host on its own
  • which item you asked about, as a product path or id
  • only if our server could not read the product from the shop's page itself (some shops block servers; some show the product only in the browser): the product's name, price, currency, brand, category and up to four photo addresses, as the page's own product data states them

Never sent

  • the full URL including query and tracking parameters
  • anything else from the page: its title, headings, descriptions, reviews or other text beyond the product fields listed above
  • the referring page
  • any user, account or install identifier
  • cookies, site storage or credentials
  • any page you did not invoke it on

What our server keeps, and for how long

Kept for 30 days, then deleted automatically

  • the shop's origin
  • whether a cheaper listing was found
  • the hour of the request, with minutes and seconds dropped

Not kept

  • your IP address is not written to any log or database on our server
  • the product you asked about
  • any identifier for you, because none is ever created

Nothing kept is enough to reconstruct what one person looked at. The server removes records older than 30 days by itself, as part of normal operation, not by hand.

Who else is involved

Our website and the extension's requests reach our server through Cloudflare, which delivers the traffic to us. Cloudflare sees the request and your IP address, as it does for any site it serves, under its own privacy terms. Our server is set not to receive or keep your IP address, and our server limits how fast it answers overall without looking at who is asking.

To find a listing, our server sends search words taken from the product's public title to the AliExpress affiliate service, and reads the product's public photo from the shop. It does not send AliExpress anything about you.

When the popup shows a match, your browser loads that photo directly from AliExpress, without telling it which page you came from. If you press "View on AliExpress", AliExpress opens in a new tab and its own privacy terms apply from there. The link carries our affiliate code, which is how we are paid; see "What it costs" on the main page.

Limited use of data

Data received is used only to perform the lookup you asked for. That is the extension's single purpose: showing you a cheaper listing that may be the item on the page you clicked.
