Acceptable use
Do not interfere with the site, attempt unauthorized access, or use automated traffic in a way that degrades access for others. Ordinary search-engine crawling and personal reference use are welcome.
Privacy
This site has no accounts, comments, advertising trackers, or third-party analytics. Food matching is performed in your browser after the reviewed data file loads.
Aggregate search statistics
When you submit a search, the browser drops queries that look like an email address, URL, or phone number, as well as queries containing control characters. Never enter personal information in the food search. Other searches send a normalized term to a same-origin endpoint so aggregate counts can identify no-match searches that may belong on the content roadmap.
The Cloudflare Analytics Engine data point contains only the normalized term and a server-derived hit-or-miss label. It does not explicitly include an IP address, user agent, cookie, or device ID. Analytics Engine currently retains data points for three months.
