The browser extension

The BottleLens extension reads wine product information from online wine shops you use it on, rates those wines and shows the results in its popup and side panel.

When you use it on a wine shop, it sends BottleLens:

• the wines it finds: names, vintages, prices, stock, product page addresses, product photos and their addresses, and the product details the shop publishes;
• the searches it makes to match each wine to its rating, and any match you correct;
• for a shop BottleLens hasn’t learned yet, or one whose layout changed, a copy of the page’s HTML with scripts, styles and inline images removed, so it can learn the layout. These copies are deleted after 90 days.
• while it learns a shop’s layout, it may also open the shop’s next catalog page, scroll or press “load more” in that tab, and send copies of those pages, and the requests the shop’s own page made for its catalog (their addresses and answers, such as the next batch of products). Cookies, sign-in and authorization headers and anything that looks like a token, session, key, email address or phone number are removed in your browser before anything is sent; it never does this on cart, checkout, account or sign-in pages, never types, and never leaves the shop.

To find ratings, the extension looks wines up on third-party wine rating websites straight from your browser. It sends them the wine names and vintages it searches for and nothing else from BottleLens. Because these lookups come from your browser, the rating websites see your IP address and, for some lookups, the cookies they have already set in your browser, just as when you visit them yourself; their own privacy policies apply.

The extension sends BottleLens what these lookups find (the matching wines, their ratings and the addresses of their rating pages), so it can match them to the wines on the shop’s page.

Requests carry an anonymous installation token, not an account or anything that identifies you. The addresses of the wine shop pages it reads are sent with them. BottleLens does not read pages on sites that aren’t wine shops, unless you ask it to scan one, and collects no other browsing history. Sharing wine data is how the extension works, so it can’t be turned off; the product database keeps past prices to show price history.

Unless you turn it off in the extension’s settings, the extension also sends anonymous usage statistics to Google Analytics: that it was installed or updated, opened, read a shop’s page (the shop’s domain and how many wines it found and rated), scanned a store, had a match corrected, or followed a link to a shop or to a wine rating website. They carry a random ID made for this purpose, not your installation token, and no page addresses beyond a shop’s domain. The language you choose in its settings stays in your browser.

This website

bottlelens.com has no accounts. It shows the wines of the country you’re in, worked out from your connection, in your browser’s language; if you pick another country or language, a cookie remembers that choice.

We measure how the site is used with Google Analytics: the pages visited, searches, and clicks on links to shops and to the extension. It sets Google Analytics cookies, which tell repeat visits apart. In the European Economic Area, the United Kingdom and Switzerland it runs only if you accept it when we ask; nothing is sent to Google before that, and you can change your choice under “Cookie settings” at the bottom of every page. Your choice is kept in your browser for a year. Google’s advertising features are turned off. Our hosting provider keeps standard server logs for security.

Shops and their data

Prices, stock and product details on this site come from each shop’s public website. Links to shops go to their own product pages, where their own privacy policies apply.
