GRAILS Companion Privacy Policy

Last updated: 20 October 2026

What the extension sends, and where

GRAILS Companion talks to exactly one server: grails.fit, operated by the same people who publish the extension. It sends only what is needed to answer the request you are making:

WhatWhenWhy
The product link of the page you are viewing When the panel is open on a Kakobuy product page To look up QC photos for that item and identify the seller
Parcel weight and destination country When you press “Check” in the shipping section To return shipping estimates
The text of a question you type When you submit a question to the assistant To answer it
A seller’s name, the item link and the shop link Only if you turn on “Help GRAILS grow” in the options (off by default), only for sellers GRAILS does not know yet, once per seller So GRAILS can add the seller to its catalogue

That is the complete list.

What the extension does not collect

What is stored on your device

The settings you choose, and a cache of GRAILS’ public catalogue data and previous QC lookups. These live in your browser’s local extension storage, are never synced off-device, and are removed when you uninstall the extension.

Referral codes

On Kakobuy visits that arrive with no referral code, the extension sets GRAILS’ referral code in Kakobuy’s own AFFCODE cookie, and GRAILS may earn a commission on resulting orders at no additional cost to you.

If a referral code is already present, it is left untouched. If a creator referred you, the extension never changes their code. It only ever fills in a blank. You can disable this entirely in the extension’s options, and it keeps working.

That cookie is Kakobuy’s own, is read by Kakobuy, and contains no information about you.
