Privacy policy

How EauIndex handles your information. Last updated September 30, 2026.

What we collect

  • Anonymous, cookie-free page analytics (page views, referring site, country, device type) through a self-hosted analytics tool. No advertising trackers.
  • When you click a retailer link we record the listing, the page it came from and the referring site, without personal identifiers, to count clicks.
  • When you use EauIndex inside an AI assistant, the assistant sends us only what the answer needs. See AI assistant integrations below.
  • If we launch email price alerts, the email address you give us, used only to send the alerts you ask for, with an unsubscribe link in every email.

AI assistant integrations

You can use EauIndex inside ChatGPT, Claude, Perplexity and other assistants that support MCP (our server at eauindex.com/mcp), or through our public API. In both cases the assistant's servers, not your device, contact ours.

  • What a request carries: the tool the assistant chose and its inputs, such as a fragrance name or id, a price, a bottle size, a store name or a gift budget. It does not carry your name, email address, account, chat history or location, and we never ask the assistant for them.
  • What we keep: nothing from the request itself. Inputs are used to answer that one request and are not stored in our database. Our server writes an ordinary access log line for each request (the time, the network address that connected, which is the assistant provider's or our own proxy's rather than yours, the address path such as /mcp, and the response status). For MCP requests the log does not include what was asked. The public API's assistant endpoints keep a per-address request count in memory for one minute to limit abuse.
  • Why: to answer the request, keep the service secure and fix errors. We do not use these logs for advertising, do not sell or share them, and do not link them to anything else.
  • How long: access logs stay on our server only, are not copied to backups, are overwritten as they fill and are deleted whenever the server software is updated, which usually happens within a few days.
  • Links in answers go to eauindex.com pages and carry a tag (such as utm_source=mcp) so our cookie-free analytics can count visits that came from an assistant. They are not affiliate links.
  • Your conversation itself is covered by your assistant provider's privacy policy (OpenAI, Anthropic, Perplexity or another).

Your choices

  • You can stop using EauIndex in an assistant at any time by removing or turning off the connector in that assistant's settings.
  • Every email we send has an unsubscribe link. To see or delete the email address we hold for you, write to the address below.

What we do not do

We do not sell personal information, and we do not share it except with service providers that run the site for us. Retailers you visit through our links have their own privacy policies.
