The Veriloot extension runs only on the sixteen marketplace sites listed at https://veriloot.gg/en/privacy#extension. On a listing page, it reads what names the item on screen and sends two things to veriloot.gg over HTTPS: the item name and the page's marketplace. It sends no cookie, no account identifier and not the page address. Like any request, it carries your IP address and the extension's origin (on Firefox, a random identifier drawn at install time), which the server checks without recording. Requests are counted per IP address in memory only, to limit abuse. The response is kept for one minute in the extension's memory; the list of paused marketplaces is kept for one hour in session storage, cleared when the browser closes. Since version 0.5.2, two values are written to the extension's local storage and never sent: how many cards have shown a cheaper price elsewhere (counted up to five) and whether you clicked the "Rate the extension" link or removed it. The extension sets no cookie, contains no analytics and changes no link on the page. No data is sold or passed on to third parties. Full policy: https://veriloot.gg/en/privacy#extension.
