Taobao Companion · 1.1.3 · 15 October 2026

The extension reads text, price labels, and the current product URL on
supported Taobao/Tmall shopping pages. It translates text and adds optional
currency estimates and an affiliate purchase button. It does not read or
change entered form values or contenteditable text.

Translation runs locally using the bundled OPUS-MT model and ONNX runtime.
Text is passed between extension contexts on the same device and is not
sent to a translation server. No remote executable code is loaded. Original
text, translated text, and model caches stay in browser memory.

Preferences and currency reference rates are stored locally. The publisher
referral code is fixed in the extension and cannot be edited in settings.
There is no analytics, telemetry, credential access, or history collection.

For currency conversion the extension requests a fixed public CNY rate feed
from api.frankfurter.dev at most once a day after successful caching. A
failed request can be retried later. This request contains no page text,
product link, price, selected currency, account details, or cookies. Like
any network request, the receiving infrastructure can observe connection
metadata such as the IP address. Rates are applied locally to prices.

Clicking Buy with KakoBuy opens kakobuy.com with the current canonical
product URL and the publisher’s fixed referral code. KakoBuy handles that visit and
any cookies under its own policies. The extension does not read, set, or
replace cookies, and performs no background affiliate redirects.
Qualifying affiliate purchases may earn commission. Welcome coupons, where
available, follow KakoBuy eligibility and redemption terms; savings are not
guaranteed by this extension.

Permissions: storage for preferences/rates; the local translation worker runs
in the extension background page; api.frankfurter.dev access for currency reference data. Content
scripts only run on supported HTTPS Taobao/Tmall domains. Recognized account,
cart, and checkout pages are excluded. On Taobao/Tmall sign-in pages fixed
page text is translated with the built-in dictionary only (the model does not
run there); entered values and submitted form values are never read or
changed. No access to all websites.

After installation a local welcome page opens once. It can save a display
currency, preset from the browser's language region on the device, and it
links to KakoBuy registration with the publisher's referral code. Nothing
from it is sent anywhere except the same rate request described above.

Use the extension popup to switch features off. Remove the extension from
your browser's extensions page to remove its settings. The installed files remain
in the local folder until you delete them yourself.

Limited Use: Information accessed by this extension is used only to provide
the disclosed translation, currency, and user-requested product-opening
features, consistent with Mozilla's add-on policies. It is not sold, used for personalized advertising,
or provided to the developer for human review.
